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)

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.

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.

Objective:To investigate the clinical effect of anterior cervical release and posterior fixation in the treatment of irreducible atlantoaxial dislocation with retropharyngeal internal carotid artery.Methods:Thirteen patients with irreducible atlantoaxial dislocation of retropharyngeal internal carotid artery from January 2015 to July 2019 were treated with anterior cervical release and posterior fixation. There were 8 males and 5 females, aged from 34 to 65 years with an average of 46.1±12.6 years. Positive, lateral and dynamic X-ray films, MR and CTA were performed before operation. There were 4 cases with bilateral retropharyngeal internal carotid artery and 9 cases with unilateral retropharyngeal internal pharyngeal artery. The time of operation, the amount of bleeding and intraoperative and postoperative complications were recorded. The main observations were Japanese Orthopaedic Association (JOA) score, atlantodental interval (ADI), Chamberlain line (CL), and changes in the morphology of the retropharyngeal internal carotid artery and implant fusion.Results:All the operations completed successfully. The operation time was 210-260 min, the average was 245±21 min; the blood loss was 350-600 ml, the average blood loss was 490±107 ml. There was no injury of internal carotid artery, vertebral artery, spinal cord or nerve root during the operation. All patients were followed up for 9 to 24 months, with an average of 15.1±6.2 months. Preoperative JOA score was 6.9±2.3 points, 1 month after operation was 13.5±2.5 points, and the last follow-up was 14.3±2.1 points. The difference was statistically significant ( F=30.91, P<0.001). The difference between 1 month after operation and before operation was statistically significant ( P<0.001), and the improvement rate of JOA score was 75.6%±15.2%. There was no significant difference between the last follow-up and 1 month after operation ( P>0.05). The preoperative ADI was 8.9±2.2 mm, 1 month after operation was 1.1±0.8 mm, and the last follow-up was 1.2±0.9 mm. The difference was statistically significant ( F=114.69, P<0.001). The difference between 1 month after operation and before operation was statistically significant ( P<0.001), and ADI had returned to normal level. There was no significant difference between the last follow-up and 1 month after operation ( P>0.05). The preoperative CL was 11.7±4.8 mm, 1 month after operation was 1.6±2.1 mm, and the last follow-up was 1.8±2.3 mm. The difference was statistically significant ( F=34.19, P<0.001). The difference between 1 month after operation and before operation was statistically significant ( P<0.001), and the position of odontoid process returned to normal level. There was no significant difference between the last follow-up and 1 month after operation ( P>0.05). Bone graft fusion was received at 6 to 12 months after operation, with an average of 10.2 months. Conclusion:CTA examination should be performed before anterior release of atlantoaxial dislocation to understand the position and shape of internal carotid artery. Anterior cervical release combined with posterior bone graft fusion is an effective method for the treatment of irreducible atlantoaxial dislocation with retropharyngeal internal carotid artery without increasing the risk of internal carotid artery injury.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Abstract Introduction The number of pressure measurements that need to be recorded using high-resolution manometry (HRM) for the accurate evaluation of pharyngeal function is not well established. Objective The purpose of this study is to clarify the number of swallows required to obtain an accurate pharyngeal manometric profile of a person. Methods Forty healthy adults performed a dry swallow and bolus swallows using 3-, 5-, or 10 ml of water and underwent measurements using the Starlet HRM system. Each subject underwent 10 swallows for each of the four bolus volume conditions. Results The mean of up to seven measurements of maximum pre-swallow upper esophageal sphincter pressure with 10 ml of swallow was close to the mean of up to eight measurements in 95% of the subjects. Similarly, the rate of change of the average for the eighth and ninth measurements and the rate of change for the average of the ninth and tenth measurements were less than 5 %. When the other parameters were similarly measured up to the sixth measurement, no major change in the average value was observed even if more measurements were taken. Conclusion A minimum of six measurements are required, and seven swallows are sufficient for evaluating the pharyngeal manometric profile of a single person. This number of measurements can be a useful criterion when performing HRM measurements on individual subjects.

ABSTRACT Objective: to survey the Brazilian participation in original and review articles published in the Dysphagia journal. Methods: original and review articles in volumes 1 to 35, quantifying all those developed in Brazil, the diseases researched, the places where the investigations were conducted, and the number of citations they received, were analyzed. The categorical variables are presented in relative and absolute frequencies. Literature Review: a total of 35 Brazilian manuscripts were published. The most researched disease was Parkinson's, followed by Chagas disease, stroke, and the physiology of swallowing. The highest number of publications was carried out at the Universidade de São Paulo, campus at Ribeirão Preto, SP, and the Universidade Federal de São Paulo, capital city. Between 2001 and 2010, 14 manuscripts were published (3.7% of the journal), and between 2011 and 2020, 20 were published (2.9% of the journal). By 2019, the manuscripts had received 481 citations - 17 citations per article between 1998 and 2009, and 14, between 2010 and 2019. Conclusion: Brazilian manuscripts are regularly published in the Dysphagia journal and have a scientific impact. However, there has not been a progressive increase in the number of published articles.

A pesquisa teve como objetivo avaliar se radiografias panorâmicas de boca fechada podem ser usadas para observação dos tecidos moles e resistência do fluxo aéreo nas vias aéreas (VA), principalmente da faringe (naso, velo, oro e hipofaringe). Para averiguação do potencial obstrutivo das vias aéreas foram estudados 65 indivíduos adultos (54 do gênero feminino e 11 do gênero masculino), 45 com dores orofaciais e 20 assintomáticos. Estabeleceram-se parâmetros através de uma nova análise radiográfica para avaliação da presença de estruturas de tecido mole potencialmente obstrutoras do fluxo respiratório. Investigou-se a influência que a dor orofacial poderia exercer no fluxo aéreo destas vias respiratórias da cavidade nasal até a entrada dos pulmões. Estes parâmetros foram correlacionados à presença e localização de obstruções de vias aéreas (VA), através da técnica de oscilometria, mensurando diferenças do fluxo aéreo durante o repouso por via nasal e bucal. Secundariamente averiguou-se a possibilidade do uso das radiografias panorâmicas para a determinação da classificação de Angle dos pacientes determinada clinicamente. A classe molar de Angle foi confirmada com facilidade através das radiografias panorâmicas de boca fechada, acrescida da vantagem de visualização bilateral da mandíbula, ao invés da superposição dos lados direito e esquerdo como ocorre nas radiografias cefalométricas, comumente utilizadas para este fim. Concluiu-se que as radiografias panorâmicas de boca fechada são úteis para visualização e investigação preliminar de tecidos moles e do fluxo das vias aéreas superiores, principalmente da nasofaringe, velo e orofaringe, e a cavidade nasal, permitindo a detecção de locais com estreitamento potencialmente obstrutivos ao fluxo aéreo. A análise panorâmica facilitou a avaliação da simetria entre os lados direito e esquerdo das estruturas supracitadas. A presença de dor orofacial não influenciou o fluxo aéreo das VAS(AU)
The objective of this study was to evaluate the use of closed-mouth panoramic radiographs for visualization of soft tissues and airflow resistance of upper airways, especially the pharynx (naso, velo, oro, and hipopharynx regions). This study analyzed 65 adult individuals (54 of the feminine gender and 11 of the masculine gender), 45 with orofacial pain and 20 with no symptoms. Parameters were stablished using a new radiographic analysis for evaluation of the potentially obstructive soft tissues in the airways from the nasal cavity to the lungs. The influence of orofacial pain on the respiratory airflow was investigated. These parameters were correlated to the presence and level of the airway obstruction (VA), using forced oscillation technique or oscillometry were measured by the nose and mouth. The Angle's classes previously determined on the clinical way were verified. The results demonstrated that the closed-mouth panoramic radiographs can be used to soft tissues visualization and initial investigation of airways, mostly at nasopharynx and oropharynx, their potentially obstructive sites, nasal cavity, symmetry between right and left sides of these structures. The analysis of the results also demonstrated, as a specific objective, that the closed-mouth panoramic radiographs could be used easily to the confirmation of the Angle's clinical classification. The closed mouth panoramic radiography showed an advantage of maxillar and mandibular bilateral visualization, instead of the right and left sides overlapping as it occurs in the usually used cephalometric radiography. The closed mouth panoramic radiography showed an advantage of maxillar and mandibular bilateral visualization, instead of the right and left sides overlapping as it occurs in the usually used cephalometric radiography. The orofacial pain did not influence the upper airways

Leopard attacks on humans are reported most often from the Indian subcontinent. The bite wounds are complex injuries infected with polymicrobial inoculum and may present as punctures, abrasions, lacerations or avulsions. The presentation and acceptable treatment of these injuries vary according to the wound. We hereby describe the clinical presentation and treatment of a male victim with leopard bite injuries on the head and neck region. As bite injuries are commonly found on and around the face, maxillofacial surgeons should be familiar with the therapy. Through thorough clinical and radiological examination, it is essential to prevent missing any hidden injuries, which can easily turn lethal. To benefit the rural population, more health facilities need to be established in remote areas.

Objective:To explore the effect of the pharyngeal pressure feedback training on pharyngeal constriction in persons with swallowing disorders caused by brainstem lesions.Methods:Twenty patients with disordered swallowing caused by a brainstem lesion were randomly divided into a control group and an intervention group, each of 10. Both groups received routine swallowing training including oral sensorimotor training, neuromuscular stimulation and balloon catheter dilation, while the intervention group was additionally provided with two weeks of pharyngeal pressure feedback training. Before and after the treatment, both groups were evaluated in terms of the peak pressure of superior and inferior pharyngeal constriction, endoscopically and also using the functional oral intake scale.Results:There was no significant difference between the two groups in any measure before the intervention. Afterward, both groups had improved significantly by all of the measurements, but the average peak upper pharyngeal pressure, the average intake scale score and the endoscopy results of the intervention group were all significantly better than the control group′s averages.Conclusions:Pharyngeal pressure feedback training can significantly relieve swallowing disorders caused by brainstem lesions.
