Traumatic pharyngeal perforation secondary to a syndesmophyte. / Perforación faríngea traumática secundaria a sindesmofito.

We report the case of a 57-year-old man who presented at the emergency department with injuries to his face and head after falling down the stairs. A head computed tomography examination done because he complained of an intense headache revealed air bubbles in the retropharyngeal space. Given this finding, a computed tomography of the neck was done to evaluate the possibility of pharyngeal perforation. Traumatic pharyngeal perforations are uncommon, but those caused by the calcification of the anterior longitudinal ligament, as in our case, are even more uncommon.

LwPTL: a novel classification for upper airway collapse in sleep endoscopies.

INTRODUCTION: There is no consensus on a single classification system for the obstructive findings in drug-induced sleep endoscopy. Previous classification systems have neglected to address the upper retropalatal obstruction, the segmental division of the lateral pharyngeal wall and the primary or secondary nature of laryngeal collapse. OBJECTIVE: To propose, illustrate and evaluate a more comprehensive and yet simple classification for drug-induced sleep endoscopy findings. METHODS: Cross sectional study in a tertiary sleep surgery unit. A total of 30 patients with obstructive sleep apnea underwent drug-induced sleep endoscopy according to a new classification system called LwPTL, and its findings were analyzed according to obstructive sleep apnea severity and body mass index. LwPTL incorporates the description of upper retropalatal collapse, distinguishes the lateral pharyngeal wall collapse into three levels and clarify when laryngeal collapses are primary or secondary. RESULTS: 93.3% of the patients presented lateral pharyngeal wall collapse, usually at the level of the velum (73.3%). 80% presented multilevel collapse. Regarding the upper retropalatal region, LwPTL identified 10% of the cases presenting lateral salpingopharyngeal obstruction and 6.6% with high palatal collapse. 3.3% presented epiglottic collapse. Patients presenting lower levels of collapse, either from the lateral wall and/or tongue and/or larynx, represented 30% of the cases and had significantly more severe obstructive sleep apnea, without significant differences in body mass indexes. CONCLUSION: LwPTL seems a simple and straightforward staging system for classifying drug-induced sleep endoscopy, distinguishing the important upper retopalatal obstruction and the primary and secondary laryngeal collapses, providing more information for appropriate treatment selection.

Relationship between the Volume of the Upper Airways and the Mandibular Angle Analyzed in Computed Tomography Scans / Relação do Volume das Vias Aéreas Superiores com o Ângulo Mandibular Analisadas em Tomografias Computadorizadas

Several variables can influence the treatment and outcome of orthognathic surgery, one of which is the angle of the mandibular ramus. The objective of this study is to analyze the upper airways (UA) of patients prior to orthognathic surgery, using cone-beam computed tomography (CBCT) and to correlate their volume with the angle of the mandibular ramus. DICOM (Digital Image Communication in Medicine) images of a radiology clinic were used, with a survey of 124 full face CBCT scans, from 2015 to 2018, and the measurement of the total volume in mm³ through software. To obtain the values of the angle of the mandibular ramus, images obtained from medical reports were used, through morphological evaluation. The values were tabulated and subsequently statistical analysis was performed using the ANOVA test to assess the differences between the mean airway volumes (mm³) according to gender, age and mandibular ramus angle. However, the angle of the ramus did not influence the volume of the UA, but a greater average of UA volume was observed in male individuals and in individuals over 34 years of age. There is no evidence that it is possible to measure or predict the volume of the UA by evaluating the angle of the mandibular ramus. (AU)

Diversas as variáveis podem influenciar no tratamento e resultado de uma cirurgia ortognática, uma delas é o ângulo do ramo mandibular. O objetivo deste trabalho é analisar as vias aéreas superiores (VAS) de pacientes previamente à cirurgia ortognática, por meio de tomografia computadorizada de feixe cônico (TCFC) e correlacionar o seu volume com o ângulo do ramo mandibular. Foram utilizadas imagens DICOM (Comunicação de Imagens Digitais em Medicina) de uma clínica radiológica, com o levantamento de 124 exames de TCFC de face total, do ano de 2015 até 2018 e feita a mensuração do volume total em mm³ através de um software. Para a obtenção dos valores do ângulo do ramo mandibular foram utilizadas imagens obtidas através dos laudos médicos, mediante avaliação morfológica. Os valores foram tabulados e posteriormente feita a análise estatística com o teste ANOVA para avaliar as diferenças entre as médias de volume das vias aéreas (mm³) de acordo com o gênero, a idade e o ângulo do ramo mandibular. Contudo, o ângulo do ramo não influenciou no volume das VAS, mas uma maior média de volume de VAS foi observada nos indivíduos do gênero masculino e nos indivíduos acima de 34 anos. Não há evidências de que se é possível mensurar ou ter previsibilidade do volume de VAS, avaliando o ângulo do ramo mandibular. (AU)

Repair of post-laryngectomy pharyngocutaneous fistulas using a pectoralis major flap.

INTRODUCTION: The pectoralis major flap is a reconstructive option to consider in the treatment of pharyngocutaneous fistula after a total laryngectomy. There are not large studies assessing variables related to pharyngocutaneous fistula recurrence after removal of the larynx. Our objectives were to review the results obtained with this type of treatment when pharyngocutaneous fistula appears in laryngectomized patients, and to evaluate variables related to the results. METHODS: We retrospectively reviewed our results using either a myocutaneous or fasciomuscular pectoralis major flap to repair pharyngocutaneous fistula in 50 patients. RESULTS: There were no cases of flap necrosis. Oral intake after fistula repair with a pectoralis major flap was restored in 94% of cases. Fistula recurrence occurred in 22 cases (44%), and it was associated with a lengthening of the hospital stay. Performing the flap as an emergency procedure was associated with a significantly higher risk of fistula recurrence. Hospital stay was significantly shorter when a salivary tube was placed. CONCLUSIONS: The pectoralis major flap is a useful approach to repair pharyngocutaneous fistula. Placing salivary tubes during fistula repair significantly reduces hospital stay and complication severity in case of pharyngocutaneous fistula recurrence.

Disfagia orofaríngea na malformação de Chiari tipo I: série de casos clínicos / Oropharyngeal dysphagia in type I Chiari malformation: a clinical case series

RESUMO A malformação de Chiari tipo I é uma condição geralmente congênita de herniação das tonsilas cerebelares abaixo do forame magno, que pode levar à compressão das estruturas próximas da fossa craniana posterior ou à obstrução do fluxo do líquido cefalorraquidiano ventril. O tipo I, apesar de raro, é o mais comumente encontrado na população. Este estudo teve como objetivo relatar os achados da videoendoscopia da deglutição, avaliação fonoaudiológica, nível de ingestão oral, risco nutricional e o planejamento terapêutico em três casos de malformação de Chiari tipo I na fase adulta. Foram coletados dados com relação à avaliação fonoaudiológica de mobilidade e força de língua, Tempo Máximo de Fonação, eficiência da tosse e o Índice de Eichner. Foram analisados o nível de ingestão oral e os sinais faríngeos de disfagia em quatro consistências alimentares, de acordo com a classificação da International Dysphagia Diet Standartisation Initiative), por meio da videoendoscopia da deglutição. Para análise e classificação dos resíduos faríngeos, foi utilizado o Yale Pharyngeal Residue Severity Rating Scale, enquanto que, para rastrear o risco nutricional, foi utilizado o Malnutrition Screening Tool. Observou-se redução mobilidade e força de língua e no Tempo Máximo de Fonação, enquanto que os sinais faríngeos variaram entre os casos, com presença de fechamento glótico incompleto, escape oral posterior, deglutições múltiplas, resíduos faríngeos e penetração laríngea.

ABSTRACT Type I Chiari malformation (MCI) is a generally congenital condition of herniation of the cerebellar tonsils below the foramen magnum, which can lead to compression of structures close to the posterior cranial fossa or obstruction of the flow of ventral cerebrospinal fluid. Type I, although rare, is the most commonly found in the population. This study aimed to report the findings of video endoscopy of swallowing, speech assessment, level of oral intake, nutritional risk and therapeutic planning in three cases of Type I Chiari malformation. Data were collected regarding the assessment of mobility and strength of tongue, Maximum Phonation Time (MPT), cough efficiency and the Eichner Index. The level of oral intake and pharyngeal signs of dysphagia were analyzed in four food consistencies, according to the International Dysphagia Diet Standardization Initiative (IDDSI) classification, using swallowing video endoscopy. For analysis and classification of pharyngeal residues, the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS) was used, while the Malnutrition Screening Tool (MST) was used to track nutritional risk. Reduced tongue mobility and strength and reduced MPT were observed, while pharyngeal signs varied between cases, with the presence of incomplete glottic closure, posterior oral escape, multiple swallows, pharyngeal residues and laryngeal penetration.

Translation and adaptation of the Radiotherapy Edema Rating Scale to Brazilian Portuguese.

INTRODUCTION: Internal lymphedema is one of the sequelae of head and neck cancer treatment that can lead to varying degrees of swallowing, speech, and respiration alterations. The Radiotherapy Edema Rating Scale, developed by Patterson et al., is a tool used to evaluate pharyngeal and laryngeal edema. OBJECTIVE: To translate into Brazilian Portuguese, to culturally adapt and test this scale in patients undergoing treatment for head and neck cancer. METHODS: The process followed the international guidelines and translation steps by two head and neck surgeons and back-translation performed independently by two North-American natives. The final version of the test was evaluated based on the assessment of 18 patients by two head and neck surgeons and two speech therapists using the scales in Brazilian Portuguese. RESULTS: The translation and cultural adaptation were satisfactorily performed by the members of the committee in charge. CONCLUSION: The translation and adaptation into Brazilian Portuguese of the Radiotherapy Edema Rating Scale was successfully performed and showed to be easy to apply.

High-Resolution Manometry Contributions to the Physiology of Phonation

High-resolution manometry (HRM) is a motility diagnostic system that measures intraluminal pressure of the gastrointestinal tract using a series of closely spaced pressure sensors. The topographic plot generated by HRM software makes it possible to visualize phonation pressures at the pharynx, UES, and body of the esophagus in real time, indicating pressure intensity by color, which permits easy data interpretation. It has been largely used for swallowing study and dysphagia diagnosis. Due to the proximity of the pharyngoesophageal and laryngeal structures, this technology instigated voice researchers. Despite the few studies published so far, high-resolution manometry has yet proven to be an extremely useful tool in obtaining entire pharyngoesophageal segment pressure measurements during phonation. It also allows natural voice production not interfering with the mouth area. HRM data already brought light to subglottic pressure, vertical laryngeal excursion, cricopharyngeal muscle activation, air flow, muscle tension associated with vocalization and pressure variations associated with different phonatory stimuli.

La manometría de alta resolución (HRM, por sus siglas en inglés) es un sistema de diagnóstico de motilidad que mide la presión intraluminal del tracto gastrointestinal mediante una serie de sensores de presión dispuestos de manera cercana. El gráfico topográfico generado por el software de HRM permite visualizar las presiones de fonación en la faringe, el EEI y el cuerpo del esófago en tiempo real, indicando la intensidad de la presión mediante colores que facilitan la interpretación de los datos. Ha sido ampliamente utilizado para el estudio de la deglución y el diagnóstico de la disfagia. Debido a la proximidad de las estructuras faringoesofágicas y laríngeas, esta tecnología ha despertado el interés de los investigadores en voz. A pesar de los pocos estudios publicados hasta ahora, la manometría de alta resolución ha demostrado ser una herramienta extremadamente útil para obtener mediciones de presión de todo el segmento faringoesofágico durante la fonación. Además, permite la producción natural de la voz sin interferir en el área de la boca. Los datos de HRM ya han arrojado luz sobre la presión subglótica, la excursión laríngea vertical, la activación del músculo cricofaríngeo, el flujo de aire, la tensión muscular asociada con la vocalización y las variaciones de presión asociadas con diferentes estímulos fonatorios.

Impacto na deglutição e manejo da mucosite hipofaríngea em pacientes submetidos à quimiorradioterapia na região de cabeça e pescoço: uma revisão integrativa da literatura / Management of hypopharyngeal mucositis in patients undergoing chemoradiotherapy in the head and neck region and its impact on swallowing: an integrative literature review

RESUMO Objetivo Investigar o impacto da mucosite hipofaríngea quimiorradioinduzida na deglutição e o seu manejo, a partir de uma revisão integrativa de literatura. Estratégia de pesquisa A busca e a seleção dos artigos foram realizadas nas seguintes bases de dados: PubMed, Embase, Scopus, ScienceDirect e LILACS. Critérios de seleção Os termos de busca utilizados foram ''Pharyngeal Mucositis", ''Radiotherapy" e ''Esophagitis", com auxílio do operador booleano (AND). A equação de busca utilizada foi: ''Pharyngeal Mucositis" AND "Radiotherapy" AND "Esophagitis". A seguinte questão central orientou o estudo: "Qual a forma de avaliação e manejo da mucosite hipofaríngea induzida pela radiação na região de cabeça e pescoço e seu impacto na deglutição?". Resultados Foram identificados 75 estudos, sendo que 6 foram excluídos devido à duplicidade e 60 foram excluídos por não se encaixarem nos critérios de inclusão; os artigos restantes foram lidos na íntegra e 4 foram selecionados para fazerem parte desta revisão integrativa da literatura. Conclusão Apesar da escassa literatura e das poucas informações sobre os métodos de avaliação da mucosite hipofaríngea, os artigos apontam que, independentemente da dose de radiação, a radioterapia na região cervical causa mucosite hipofaríngea. A mucosite hipofaríngea provoca grande impacto na deglutição, resultando na necessidade de uso de via alternativa de alimentação. Além da ausência de informações quanto à avaliação e graduação da mucosite hipofaríngea, os estudos não discutem o tratamento direto ou a prevenção desse tipo de doença.

ABSTRACT Purpose To investigate the impact of chemoradiation-induced hypopharyngeal mucositis on swallowing and its management, based on an integrative literature review. Research strategy Two researchers were responsible for the search and selection of articles, within the following databases: PubMed, Embase, Scopus, Science Direct, and Lilacs. Selection criteria The search terms used were "Pharyngeal Mucositis", "Radiotherapy" and "Esophagitis", with the aid of the Boolean operator (AND). The search equation used was "Pharyngeal Mucositis" AND Radiotherapy AND Esophagitis. The following central question guided the study: "What is the assessment and management of radiation-induced hypopharyngeal mucositis in the head and neck region and its impact on swallowing?" Results 75 studies were identified, of which 6 were excluded due to duplicity and 60 were excluded for not meeting the inclusion criteria; the remaining articles were read in full and 4 were selected to be part of the integrative literature review. Conclusion Despite the scarce literature and little information on methods for evaluating hypopharyngeal mucositis, the articles point out that, regardless of the radiation dose, radiotherapy in the cervical region causes hypopharyngeal mucositis. Hypopharyngeal mucositis causes a great impact on swallowing, resulting in the need to use an alternative feeding route. In addition to the lack of information regarding the assessment and grading of hypopharyngeal mucositis, the studies do not discussitsdirect treatment or prevention.

Cuerpo extraño faríngeo migratriz. A propósito de un caso

RESUMEN Introducción: la faringe es el sitio más común de alojamiento de cuerpos extraños dentro del área otorrinolaringológica. Usualmente su diagnóstico y extracción resultan fáciles. Sin embargo, y afortunadamente, unos pocos se encarnan profundamente y causan infecciones en el cuello, o más raro aún, logran migrar y se sitúan inmediatamente por debajo de la piel. Presentación del caso: presentamos el caso de un paciente masculino de 27 años que fue atendido durante nuestra misión en Namibia en el 2018, quien se tragó una espina de pescado, la cual se alojó inicialmente en el espacio retrofaríngeo para luego migrar hasta el tejido celular subcutáneo del cuello. Discusión: el mecanismo por el cual un cuerpo extraño migra puede estar dado por la combinación del peristaltismo del esófago y los movimientos del cuello u otros factores como la configuración lineal y afilada del cuerpo extraño, la deglución forzada de alimentos de consistencia dura inmediatamente a la impactación del cuerpo extraño y la asistencia tardía del paciente a los servicios de salud. Conclusiones: la migración de un cuerpo extraño ingerido es una rara forma de evolución. Su tratamiento depende fundamentalmente de potenciales complicaciones que podrían poner en riesgo la vida del paciente.

ABSTRACT Introduction: the pharynx is the most common site of lodging of foreign bodies within the otorhinolaryngological area. Diagnosis and removal are usually easy. Fortunately, however, a few become deeply ingrown and cause neck infections, or more rarely, manage to migrate and lie just under the skin. Case presentation: we present the case of a 27-year-old male patient who was treated during our mission in Namibia in 2018, who swallowed a fish bone, which initially lodged in the retropharyngeal space and then migrated to the cellular tissue. subcutaneous neck. Discussion: the mechanism by which a foreign body migrates may be due to the combination of peristalsis of the esophagus and movements of the neck or other factors such as the linear and sharp configuration of the foreign body, the forced swallowing of food with a hard consistency immediately after impaction of the foreign body and late attendance of the patient to health services. Conclusions: the migration of an ingested foreign body is a rare form of evolution. Its treatment fundamentally depends on potential complications that could put the patient's life at risk.

RESUMO Introdução: a faringe é o local mais comum de alojamento de corpos estranhos na área otorrinolaringológica. O diagnóstico e a remoção geralmente são fáceis. Felizmente, no entanto, alguns ficam profundamente encravados e causam infecções no pescoço ou, mais raramente, conseguem migrar e ficam logo abaixo da pele. Apresentação do caso: apresentamos o caso de um paciente do sexo masculino de 27 anos que foi atendido durante nossa missão na Namíbia em 2018, que engoliu uma espinha de peixe, que inicialmente se alojou no espaço retrofaríngeo e depois migrou para o tecido celular. Discussão: o mecanismo pelo qual um corpo estranho migra pode ser devido à combinação de peristaltismo do esôfago e movimentos do pescoço ou outros fatores como a configuração linear e aguda do corpo estranho, a deglutição forçada de alimentos de consistência dura imediatamente após a impactação do corpo estranho e comparecimento tardio do paciente aos serviços de saúde. Conclusões: a migração de um corpo estranho ingerido é uma forma rara de evolução. Seu tratamento depende fundamentalmente de potenciais complicações que podem colocar em risco a vida do paciente.

Pólipo Nasofaríngeo Primário: Apresentação Incomum / Primary Nasopharyngeal Polyp: Uncommon Presentation

Os pólipos inflamatórios não neoplásicos da nasofaringe são patologias raras e de consistência frágil, que normalmente são confundidos com outras lesões desta região. Entre essas, está o nasoangiofibroma, que possui consistência firme e sangra à manipulação. J.I.R.B., 17 anos, sexo masculino, estudante, com história de dor na faringe, com obstrução nasal noturna há 2 meses, associado à queixa de volume na garganta há 1 mês. À inspeção e oroscopia, encontrou-se uma volumosa lesão de aspecto polipoide, projetando-se da orofaringe. A ressonância magnética (RM) revelou lesão volumosa com componentes císticos, hiperintenso em T1 e hipointenso em T2, de aproximadamente 8,0 cm no seu maior diâmetro no corte sagital, que se estendia da nasofaringe até a orofaringe, chegando à região da epiglote. São descritos na literatura vários estudos relatando pólipos nasofaríngeos em felinos, mas apenas um estudo na literatura médica inglesa fala sobre as propriedades clínicas e histológicas dos pólipos inflamatórios primários da nasofaringe humana. Assim, o presente caso tem grande importância, principalmente pela sua raridade, local de acometimento do pólipo inflamatório benigno, bem como o tamanho da lesão. Na abordagem de massas naso e orofaríngeas em jovens e adultos, os pólipos inflamatórios primários fazem parte dos diagnósticos a serem considerados. Apesar do pequeno número de casos, as características radiológicas e patológicas dessa lesão devem ser lembradas, minimizando o risco de serem diagnosticados incorretamente.

Non-neoplastic inflammatory polyps of the nasopharynx are rare pathologies of fragile consistency, which are usually confused with other lesions of this region. Among these, the nasopharyngeal angiofibroma, which has firm consistency and bleeds to manipulation. J.I.R.B., 17 years old, male, student, with a history of pain pharynx, and nocturnal nasal obstruction for 2 months, associated with the complaint of volume in the throat for 1 month. Inspection and oroscopy, a polypoid lesion was found, protruding from the oropharynx. Magnetic resonance imaging (MRI) revealed a massive lesion with cystic, hyperintense components on T1-weighted images and hypointense at T2, approximately 8.0 cm in its largest diameter in the sagittal section, which was out of the nasopharynx to the oropharynx, reaching the epiglottis region. Several studies reporting nasopharyngeal polyps in felines have been described in the literature, but only one study in the English medical literature talks about the clinical and histological properties of the primary inflammatory polyps of the human nasopharynx. Thus, the present case is of great importance mainly, due to its rarity, site of involvement of benign inflammatory polyp, as well as the size of the lesion. In the approach of nasopharynx and oropharyngeal masses in young and adult, the primary inflammatory polyps are part of the diagnoses to be considered. Despite the small number of cases, the radiological and pathological characteristics of this lesion should be remembered, minimizing the risk of being misdiagnosed.

Role of transpalatal advancement pharyngoplasty in management of lateral pharyngeal wall collapse in OSA / Papel da faringoplastia com avanço transpalatino no tratamento do colapso da parede lateral da faringe na AOS

Abstract Introduction Non-response to palatal surgery for OSA is a problem. Residual lateral wall hypopharyngeal collapse is the proposed mechanism of failure. Objective This study aims to evaluate the role of transpalatal advancement pharyngoplasty in non-responders to primary palatal surgery with residual lateral wall hypopharyngeal collapse. Methods This is a retrospective study that was conducted on patients who underwent transpalatal advancement pharyngoplasty for residual lateral wall hypopharyngeal. Inclusion criteria were age greater than 18-years, OSA proved by the polysomnography with apnea hypopnea index >15, lateral wall collapse at the level of hypopharynx as proved by drug-induced sleep endoscopy and had a previous tonsillectomy or previous palatal surgery for OSA. Exclusion criteria were those with no history of tonsillectomy or any other surgery for OSA and those with a missed followup. Data of included patients were collected and included gender, age, polysomnographic data like the apnea hypopnea index, oxygen desaturation and the calculated preoperative Epworth sleepiness scale. The early outcome included symptom improvement as measured by Epworth sleepiness scale score and lateral pharyngeal wall evaluation by nasopharyngoscopic examination in the first postoperative month. Late outcome measurement was performed by the 6-month postoperative polysomnography. Data were analyzed using SPSS program. Results The study included 37 patients with a mean age of (40.43 ± 6.51). The study included 26 men and 11 women. There was a statistically significant improvement of apnea hypopnea index from 37.8 ± 9.93 to 9.9 ± 2.55. In addition, a statistically significant improvement of lowest oxygen saturation from 78.9 ± 3.39 to 83.3 ± 3.31 was encountered. The patients improved clinically, and this improvement was measured by statistically significant improvement of Epworth sleepiness scale score and snoring visual analogue scale. Conclusion Transpalatal advancement pharyngoplasty widens the retropalatal airway and has a great role in the management of the vertical palate phenotype. In addition, it can have a role in the management of lateral walls, especially lateral wall hypopharyngeal collapse.

Resumo Introdução A ausência de resposta à cirurgia palatina para AOS é um problema. O colapso residual da parede lateral da hipofaringe é um mecanismo de falha proposto. Objetivo Avaliar o papel da faringoplastia com avanço transpalatino em pacientes que não responderam à cirurgia palatina primária com colapso residual da parede lateral da hipofaringe. Método Estudo retrospectivo que será feito em casos que receberam faringoplastia com avanço transpalatino para parede lateral da hipofaringe residual. Os critérios de inclusão foram idade maior que 18 anos, AOS comprovada por polissonografia com índice de apneia e hipopneia > 15, colapso da parede lateral ao nível da hipofaringe comprovado por endoscopia do sono induzido por drogas e submetidos a amigdalectomia ou cirurgia palatina anterior para AOS. Os critérios de exclusão foram pacientes sem histórico de amigdalectomia ou qualquer outra cirurgia para AOS e aqueles com perda de seguimento. Os dados dos pacientes incluídos foram coletados e incluíram sexo, idade, dados polissonográficos, como índice de apneia e hipopneia, dessaturação de oxigênio e a escala de sonolência de Epworth calculada no pré‐operatório. O desfecho inicial incluiu melhoria dos sintomas medida pelo escore da escala de sonolência de Epworth e avaliação da parede lateral da faringe por exame nasofaringoscópico no primeiro mês do pós‐operatório. A medida do desfecho tardio foi feita pela polissonografia pós‐operatória de 6 meses. Os dados foram analisados no programa SPSS. Resultados O estudo incluiu 37 pacientes com média de 40,43 ± 6,51 anos. O estudo incluiu 26 homens e 11 mulheres. Houve uma melhoria estatisticamente significante do índice de apneia e hiponeia de 37,8 ± 9,93 para 9,9 ± 2,55. Além disso, foi encontrada uma melhoria estatisticamente significante da menor saturação de oxigênio de 78,9 ± 3,39 para 83,3 ± 3,31. Os pacientes melhoraram clinicamente e essa melhoria foi medida pela melhoria estatisticamente significante no escore da escala de sonolência de Epworth e na escala escala visual analógica do ronco. Conclusão A faringoplastia com avanço transpalatino alarga a via aérea retropalatina e tem um papel importante no manejo do fenótipo do palato vertical. Além disso, ela pode ter um papel no manejo das paredes laterais, especialmente no colapso da parede lateral da hipofaringe.

Apneia Obstrutiva do Sono: caracterização do sítio obstrutivo e tipo de colapso / Obstructive Sleep Apnea: characterization of the obstructive site and type of collapse

RESUMO A Apneia Obstrutiva do Sono caracteriza-se por episódios recorrentes de colapso parcial ou completo da faringe, seguidos de diminuição da saturação de oxihemoglobina e despertares frequentes. É considerada problema de saúde pública com importantes sintomas noturnos e diurnos, impactando qualidade de vida. Seus efeitos associam-se as áreas de competência da Fonoaudiologia. Para estabelecer diagnóstico e métodos de tratamento eficientes, profissionais devem conhecer a patogênese da obstrução da via aérea superior durante o sono. Visando contribuir para a compreensão da fisiopatologia da apneia obstrutiva do sono, elegibilidade de procedimentos terapêuticos individualizados e direcionamento para terapêutica miofuncional orofacial, o presente estudo tem como objetivo descrever e ilustrar os locais e tipos de colapso da via aérea superior durante o sono. Após processos éticos, foram analisados registros originais das sonoendoscopias de uma série de casos com diagnóstico polissonográfico de apneia obstrutiva do sono. As imagens das gravações dos exames foram analisadas por cinco profissionais com expertise na área do sono. Os locais obstrutivos e tipos de colapso foram apresentados conforme classificação vigente. Os vídeos foram divididos em capturas de tela, originando figuras de cada sítio anatômico: sem colapso e com colapso. Os resultados foram apresentados por imagens dos casos, que ilustram cada colapso, predominando colapso velofaríngeo: anteroposterior, lateral ou concêntrico; seguido por colapso orofaríngeo lateral; colapso anteroposterior na hipofaringe e colapso anteroposterior da epiglote. O entendimento dos locais de obstrução e tipos de colapso ilustrados nesse estudo pode ser um preditor de respostas terapêuticas, auxiliando a compreensão das limitações ou direcionando propostas para cada paciente.

ABSTRACT Obstructive Sleep Apnea is characterized by recurrent episodes of partial or complete collapse of the pharynx, followed by decreased oxyhemoglobin saturation and frequent arousals. It is regarded as a public health issue with important night and day symptoms that impact life quality. Its effects are associated with the areas of competence of Speech and Language Pathologists. To establish efficient diagnosis and treatment methods, professionals must know the pathogenesis of upper airway obstruction during sleep. This study seeks to enlarge the understanding of obstructive sleep apnea pathophysiology, eligibility of individualized therapeutic procedures and guidance for orofacial myofunctional therapy by describing and illustrating the locations and types of upper airway collapse during sleep. We analyzed original records of Drug Induced Sleep Endoscopy exams of a series of cases with polysomnographic diagnosis of obstructive sleep apnea following the proper ethical processes. The images of the exam recordings were analyzed by five professionals with expertise in the sleep area. Obstructive sites and types of collapse were presented according to the current classification. The videos were divided into screenshots, originating figures from each anatomical site: without collapse and collapsed. The results are visualized in the images of the cases showing a predominance of velopharyngeal collapse: anteroposterior, lateral, or concentric; oropharyngeal lateral collapse; tongue anteroposterior collapse and anteroposterior collapse of the epiglottis. Understanding the obstruction sites and types of collapse illustrated in this study may help to predict therapeutic responses and learn the limitations or direct individual proposals patient.

Introducción: Uno de los tratamientos indicados para la deficiencia maxilar transversal es la expansión maxilar rápida (REM). El presente artículo trata sobre la terapia REM y muestra, a partir de una revisión bibliográfica, los diversos beneficios que esta puede brindar al paciente y los cambios que puede generar en su anatomía. Objetivos: Abordar el efecto de la terapia REM sobre la vía aérea nasofaríngea. También describir, en base a evidencia científica, los cambios que produce en la morfología y resistencia sobre la vía aérea faríngea. Esto mediante distintos métodos de estudios disponibles actualmente. Materiales y métodos: Se realizó una búsqueda bibliográfica en las bases de datos: PubMed, Clinicalkey y Epistemonikos. Se seleccionaron trabajos publicados en los últimos 8 años en adelante. De un universo total de 77 publicaciones, fueron seleccionados 12 estudios para esta revisión. Se excluyeron estudios en los cuales se realizaban acciones clínicas que escapan al tratamiento ortopédico. También se excluyeron tratamientos realizados para mejorar la vía aérea, basados en el tratamiento ortopédico del crecimiento mandibular. Resultados: En los estudios realizados mediante radiografías cefalométricas se obtuvo un aumento significativo (p <0.05) en el espacio de la vía aérea nasofaríngea, en particular en las medidas AD2 y AD-PtV, después del tratamiento ortodóncico. Por otro lado, AD1 también aumentó, pero no significativamente (p> 0.05). Conclusión: La terapia REM, en pacientes en crecimiento, logra separar la sutura palatina media aumentando el tamaño del piso de las fosas nasales y el volumen en el territorio nasofaríngeo. Se necesitan estudios con un tamaño de muestra mayor y un seguimiento a largo plazo para establecer el éxito de esta terapia.

Introduction: One of the treatments indicated for transverse maxillary deficiency is rapid maxillary expansion (REM). This article deals with REM therapy and shows, based on a bibliographic review, the various benefits that it can generate for the patient and the changes in their anatomy. Objectives: To elucidate the effect of REM therapy on the nasopharyngeal airway. Also expose, based on scientific evidence, the changes that it produces in the morphology and resistance on the pharyngeal airway. This through different study methods currently available. Materials and methods: A bibliographic search was carried out in the databases: PubMed, Clinicalkey and Epistemonikos. From a total universe of 77 publications, 12 studies were selected for this review. Results: In the studies carried out using cephalometric radiographs, a significant increase (p < 0.05) in the nasopharyngeal airway space was obtained, particularly in the AD2 and AD-PtV measurements, after orthodontic treatment. On the other hand, AD1 also increased, but not significantly (p > 0.05). Conclusion: REM therapy, in growing patients, manages to separate the middle palatal suture by increasing the size of the floor of the nostrils and the volume in the nasopharyngeal territory. Studies with a larger sample size and long-term follow-up are needed to establish the success of this therapy.

Preescolar con divertículo de Zenker y hallazgo intraoperatorio de cuerpo extraño esofágico / Preschool-age child with Zenker's diverticulum and intraoperative finding of an esophageal foreign body

Introducción. El divertículo de Zenker es una evaginación sacular ciega que puede presentarse a nivel faringoesofágico. No se conoce exactamente su incidencia en la edad pediátrica, constituyendo una patología muy infrecuente. La sintomatología es inespecífica, lo que dificulta el diagnóstico precoz y determina un mayor riesgo de complicaciones asociadas. Caso clínico. Paciente preescolar femenina con cuadro recurrente de emesis con deshidratación, posteriormente asociado a disfagia, a quien se le diagnosticó un divertículo de Zenker. Se realizó tratamiento quirúrgico con hallazgo intraoperatorio de dilatación esofágica, un área de estenosis secundaria al hallazgo incidental de un cuerpo extraño y divertículo de Zenker en la región lateral del esófago dilatado. Discusión. Esta patología es extremadamente rara, pero se debe tener en cuenta dentro de los diagnósticos diferenciales en pacientes con sintomatología faringo-esofágica. Conclusión. Se presenta una preescolar sin antecedente de procedimientos esofágicos o malformaciones congénitas asociadas con diagnóstico de un divertículo de Zenker y dilatación esofágica por un cuerpo extraño, tratada quirúrgicamente de forma exitosa.

Introduction. Zenker's diverticulum is a blind saccular evagination that can present at the pharyngoesophageal level. Its incidence in pediatric age is not exactly known, constituting a very infrequent pathology. The symptoms are nonspecific, which makes early diagnosis difficult and determines a higher risk of associated complications.Clinical case. Female preschool patient with recurrent dehydration due to emesis, later associated with dysphagia, who was diagnosed with Zenker's diverticulum. Surgical treatment was performed with intraoperative finding of esophageal dilation, an area of stenosis secondary to the incidental finding of a foreign body, and a Zenker's diverticulum in the lateral region of the dilated esophagus. Discussion. This pathology is extremely rare, but it should be taken into account within the differential diagnoses in patients with pharyngo-esophageal symptoms. Conclusion: We present a preschool female patient with no history of esophageal procedures or congenital malformations associated with a diagnosis of Zenker's diverticulum and esophageal dilation due to a foreign body, successfully treated surgically.

Estenosis nasofaríngea: a propósito de la leishmania mucocutánea / Nasopharyngeal stenosis: about mucocutaneous leishmania

La leishmaniasis es una enfermedad protozoaria intracelular. Una de sus formas de presentación es la mucocutánea, que es secuela de la leishmania cutánea y solo se presenta en el 1 % al 5 % de quienes la padecen. Afecta la mucosa nasal, faríngea y laríngea, lo que ocasiona disnea y disfagia. Se presenta el caso de una paciente de 76 años con síntomas obstructivos nasales, en quien se evidenciaron múltiples sinequias nasales y faringolaríngeas. Ante la sospecha clínica de la enfermedad, es importante recordar que el diagnóstico se realiza a través de la intradermorreacción de Montenegro o títulos de inmunofluorescencia indirecta superiores a 1:16, y su tratamiento incluye el antimonio pentavalente, uno de los más utilizados; sin embargo, este tiene alto grado de recurrencias y efectos secundarios, por lo que la anfotericina B se convierte en el tratamiento de elección. En algunos casos, el manejo quirúrgico puede ser de gran utilidad para la mejoría de síntomas y secuelas de la enfermedad. Entonces, la leishmania mucocutánea se convierte en una enfermedad de interés para los otorrinolaringólogos, quienes con el conocimiento de la historia natural de la misma pueden realizar un manejo temprano y la adecuada corrección de secuelas para mejorar la calidad de vida de los pacientes.

Leishmaniasis is an intracellular protozoan disease. One of its forms of presentation is mucocutaneous, which is sequela of cutaneous leishmania and only occurs in 1% to 5% of those who suffer it. It affects the nasal, pharyngeal and laryngeal mucosa, causing dyspnea and dysphagia. We presented a case of a 76-year-old patient with obstructive nasal symptoms, who evidenced multiple nasal and pharyngolaryngeal synechiae. Given the clinical suspicion of the disease, it is important to remember that the diagnosis is made through the Montenegro intradermal reaction and or indirect immunofluorescence titers greater than 1:16, and the treatment includes pentavalent antimonial, one of the most used; however, it has a high degree of recurrence and side effects, so amphotericin B becomes the treatment of choice. In some cases, surgical management can be very useful for the improvement of symptoms caused by the disease. Thus, mucocutaneous leishmania becomes a disease of interest for otorhinolaryngologists, who, with knowledge of its natural history, can carry out early management and adequate correction of sequelae to improve the patients' quality of life.

Otorhinolaryngology manifestations secondary to oral sex. / Lesiones otorrinolaringológicas secundarias al sexo oral.

INTRODUCTION: Over the last few years, oral and pharyngeal signs and symptoms due to oral sex have increased significantly. However, no review articles related to this subject have been found in the medical literature. The objective of our study was to identify otorhinolaryngological manifestations associated with orogenital/oroanal contact, both in adults and children, in the context of consensual sex or sexual abuse. METHODS: We performed a review of the medical literature on otorhinolaryngological pathology associated with oral sex published in the last 20 years in the PubMed database. RESULTS: Otorhinolaryngological manifestations secondary to oral sex practice in adults can be infectious, tumoral or secondary to trauma. The more common signs and symptoms found in the literature were human papillomavirus infection (above all, condyloma acuminata and papilloma/condyloma), oral or pharyngeal syphilis, gonococcal pharyngitis, herpes simplex virus infection and pharyngitis from Chlamydia trachomatis. The incidence of human papillomavirus -induced oropharyngeal carcinoma has dramatically increased. In children past the neonatal period, the presence of condyloma acuminatus, syphilis, gonorrhoea or palatal ecchymosis (the last one, unless justified by other causes) should make us suspect sexual abuse. CONCLUSIONS: Sexual habits have changed in the last decades, resulting in the appearance of otorhinolaryngological pathology that was rarely seen previously. For this reason, it is important for primary care physicians to have knowledge about the subject to perform correct diagnosis and posterior treatment. Some sexual abuse cases in children may also be suspected based on the knowledge of the characteristic oropharyngeal manifestations secondary to them.

Pharyngeal tuberculosis: Report of 5 cases. / Tuberculosis faríngea: 5 casos clínicos.

Tuberculosis is a public health problem for many countries, whether rich or poor. Extranodal ENT locations are rare, and it prevails in the cavum in the pharyngeal region. Based on a 3-year retrospective study of 5 clinical cases, the authors aim to highlight the epidemiological, clinical, radiological, therapeutic and prognostic aspects of this disease. Clinical aspects are not specific and there is often confusion in the differential diagnosis with tumoral lesions. Positive diagnosis is guided by the clinical and the radiological findings, and confirmed by histology.

Respostas pressóricas faringeana, esofágica e do esfíncter esofagiano a tarefas vocais à luz da manometria de alta resolução / Pharyngeal, upper esophageal sphincteric and esophageal pressures responses related to vocal tasks at the light of high resolution manometry

ABSTRACT BACKGROUND: High-resolution manometry (HRM) represents a potential tool for measuring pharyngoesophageal phonation pressures. OBJECTIVE: This study aims to evaluate pharyngeal, esophageal upper sphincteric and esophageal pressures during different phonation tasks. METHODS: 12 (six males, mean age 27 years) professional singers underwent HRM and produced four different vocal tasks at low, medium and high vocal loudness: vowel /ae/, ascending five note scale, word /hey/ and word /go/. Pressures were measured at pharynx, upper esophageal sphincter (UES) and esophagus. Visual analysis of the HRM topographic plots were performed. RESULTS: Esophageal pressures are higher during vocalization than at rest. Pharyngeal and UES phonation pressures does not differ significantly from rest pressures. Visual analysis of the topographic plots showed an important UES pressure increasement during phonation. CONCLUSION: HRM is a valuable tool for measuring pharyngoesophageal pressures during phonation. Esophageal pressures are higher during phonation than at rest and tend to increase with vocal loudness increment. The topographic plot provides additional data about phonatory mechanism physiology, especially at the UES region.

RESUMO CONTEXTO: A manometria de alta resolução (MAR) é uma ferramenta de grande potencial para mensuração das pressões faringoesofágicas durante a fonação. OBJETIVO: O estudo visa avaliar pressões faringianas, do esfíncter esofagiano superior e do esôfago durante manobras fonatórias. MÉTODOS: Doze (seis homens, idade média 27 anos) cantores profissionais foram submetidos à MAR e produziram quatro tarefas vocais em intensidade baixa, média e alta: vogal / ae /, escala ascendente de cinco notas, palavras /hey/ e /go/. Pressões aos níveis da faringe, esfíncter esofagiano superior e esôfago foram aferidas além de análise visual dos traçados. RESULTADOS: Pressões esofágicas foram maiores na vocalização que no repouso. Pressões da faringe e esfíncter esofagiano superior durante a fonação não foram diferentes que no repouso. Análise visual dos traçados mostrou importante incremento da pressão do esfíncter durante a fonação. CONCLUSÃO: MAR é uma ferramenta valiosa para mensurar as pressões faringoesofágicas durante a fonação. Pressões esofágicas são maiores durante a fonação que no repouso e tendem a aumentar com maior intensidade sonora. Análise visual dos traçados mostram dados adicionais sobre a fisiologia do mecanismo da fonação, especialmente na região do esfíncter esofagiano superior.

Horse choanae are directionally asymmetric / Las coanas de los caballos son direccionalmente asimétricas

SUMMARY: Studies related to the upper respiratory pathway asymmetries are still scarce in the veterinary literature. We present here a study of choanae asymmetries of a pure horses belonging to "Cavall Pirinenc Català" (Pyrenean Horse Breed). For this goal, the palates of 23 dry skulls with no apparent pathologies were photographed and evaluated using geometric morphometrics. On each photo, we identified and digitized a total of 26 points (subset of 2 mid-sagittal, 4 paired landmarks (discrete homologous points) and 10 semilandmarks (points on an outline determined by extrinsic criteria) per side on the choana. Both fluctuating and directional asymmetries appeared statistically significant, the latter accounting more than half of the total variation. The lateral bend observed in horse choanae may be due to the asymmetrically positioned nasal passages. So detected equine choana asymmetry must rather be considered functional, with no clinical implication and presents an important consideration when equine choanae shape.

RESUMEN: Los estudios relacionados con las asimetrías de las vías respiratorias superiores aún son escasos en la literatura veterinaria. Presentamos un estudio de coanas asimetrías de un caballo puro perteneciente al "Cavall Pirinenc Català" (Raza del Caballo de los Pirineos). Para ello, se fotografiaron y evaluaron los paladares de 23 cráneos secos sin patologías aparentes mediante morfometría geométrica. En cada foto, identificamos y digitalizamos un total de 26 puntos (subconjunto de 2 puntos medio sagitales, 4 puntos de referencia emparejados (puntos homólogos discretos) y 10 puntos semillanos (puntos en un contorno determinado por criterios extrínsecos) por lado de la coana. Ambos fluctúan Las asimetrías direccionales aparecieron estadísticamente significativas, representando estas últimas más de la mitad de la variación total. La curvatura lateral observada en las coanas de caballo puede deberse a los conductos nasales asimétricamente posicionados. Por lo tanto, la asimetría de coanas equinas detectada debería considerarse funcional, sin implicación clínica y presenta una importante consideración cuando se forman coanas equinas.
