[Effect of maxillary expansion combined with orofacial myofunctional therapy on the position of the tongue of children with mouth breathing].

Objective:This study aimed to investigate the change of the position of the tongue before and after combined treatment of maxillary expansion and orofacial myofunctional therapy in children with mouth-breathing and skeletal class Ⅱmalocclusion. Methods:A total of 30 children with skeletal class Ⅱ malocclusion and unobstructed upper airway were selected. The 30 children were divided into mouth-breathing group（n=15） and nasal-breathing group（n=15） and CBCT was taken. The images were measured by Invivo5 software. The measurement results of the tongue position of the two groups were analyzed by independent samples t-test. 15 mouth-breathing children with skeletal class Ⅱ malocclusion were selected for maxillary expansion and orofacial myofunctional therapy. CBCT was taken before and after treatment, the measurements were analyzed by paired sample t test with SPSS 27.0 software package. Results:The measurement of the tongue position of the mouth-breathing and nasal-breathing groups were compared, the differences were statistically significant（P<0.05）. The measurement of the tongue position showed significant difference after the combined treatment of maxillary expansion and orofacial myofunctional therapy in children with mouth-breathing and skeletal class Ⅱmalocclusion（P<0.05）. Conclusion:Skeletal class Ⅱ malocclusion children with mouth-breathing have low tongue posture. The combined treatment of maxillary expansion and orofacial myofunctional therapy can change the position of the tongue.

Effect of oral Xiao-xian decoction combined with acupoint application therapy on pediatric adenoid hypertrophy: A randomized trial.

BACKGROUND: This study aimed to observe the clinical effects of Xiao-xian decoction combined with acupoint application therapy (AAT) for treating pediatric adenoid hypertrophy (AH). METHODS: We randomly divided 93 AH children into 3 groups: AAT alone; Xiao-xian decoction + AAT; control: Montelukast oral therapy. All participants were treated for a month. We used the traditional Chinese medicine syndrome score to evaluate the clinical efficacy and the obstructive sleep apnea-18 scale to evaluate the quality of life. RESULTS: The major symptoms (nasal congestion, open mouth breathing, snoring, and tongue image) and secondary symptoms of patients treated with Xiao-xian decoction + AAT significantly improved compared to before treatment. The pairwise comparison between groups showed that snoring, tongue, secondary symptoms, and total effective rate of the combined treatment group were better than the control and AAT alone. Additionally, the open-mouth breathing, quality of life, and recurrence rate did not differ after treatment. CONCLUSION: Oral Xiao-xian decoction combined with AAT significantly improved the symptoms and signs of nasal congestion, open-mouth breathing, snoring, tongue, and quality of life of AH children and may be used as a long-term treatment for AH.

Comparison of rapid maxillary expansion and pre-fabricated myofunctional appliance for the management of mouth breathers with Class II malocclusion.

OBJECTIVE: Pre-fabricated myofunctional appliances and rapid maxillary expansion (RME) has been used for the treatment of mouth-breathers with Class-II malocclusion. This study aimed to compare the treatment effects of hyrax and pre-fabricated myofunctional appliance (T4K) for the management of mouth breathers with Class II Malocclusion in mixed dentition stage. PATIENTS AND METHODS: Case records of mouth breathers with Class II Division 1 malocclusion patients treated at our institute with T4K or hyrax appliance between June 2015 to May 2019 were retrieved. The Pancherz analysis was used to compare the treatment effects. RESULTS: Data of 28 patients (14 in each group) were compared. Significant advancement of maxilla was seen in both groups while mandibular length improved only with the T4K appliance. SNA and SNB changes were significantly greater in the T4K group. Molar relationship improved in both groups. Molar correction was obtained by 55.6% skeletal change and 44.4% dental change with RME. In the T4K group the corresponding values were 48.1% and 51.9% respectively. CONCLUSIONS: Our results suggest that both pre-fabricated myofunctional appliance and RME are suitable for the treatment of mouth breathers with Class II malocclusion in the mixed dentition period. Sagittal correction of maxilla and mandible may be somewhat better with the T4K appliance. Although the dental compensation may be slightly more with the T4K appliance and it may inhibit the skeletal remodeling.

Influence of mentalis muscle relaxation on oronasal breathing / A repercussão do relaxamento do músculo mentual na respiração oronasal

ABSTRACT Purpose: to investigate the existence of changes in the electromyographic patterns of the mentalis and inferior orbicularis oris muscles in oronasal breathers, submitted to massage therapy on the mentalis muscle. Methods: a controlled blind placebo experiment, with a sample of 19 oronasal breathers (1 man and 18 women), mean age (standard deviation) 22.3 (2.63) years, randomly divided into control and experimental groups, respectively with 7 and 12 volunteers. The experimental group alone underwent myotherapy with massages for 3 months, while electromyographic data were collected from both groups at the beginning and end of the treatment, both at rest and when swallowing water. The analysis of variance was conducted to test the existence of differences between the means; the 5% significance level was used. Results: the analysis of variance revealed signs of interaction between the group and phase effects when analyzing the root mean square values of both the inferior orbicularis oris and the mentalis muscles. As expected, no signs of significant differences were found between the means of the phases in the control group. On the other hand, signs of significant difference were found in the experimental group, with reduced root mean square values in both muscles. The inferior orbicularis oris muscle, which in the pre-phase had a mean (standard deviation) of 202.10 (161.47) µV, had, in the post-phase, values of 131.49 (159.18) µV. The mentalis muscle, in its turn, had in the pre- and post-phase, respectively, a mean (standard deviation) of 199.31 (279.77) µV and 114.58 (253.56) µV. Conclusion: given that no effect was detected in the control group, the decrease in the root mean square values of the mentalis and inferior orbicularis oris muscles in oronasal breathers was attributed to the massage therapy on the mentalis muscle.

RESUMO Objetivo: investigar a existência de modificações dos padrões eletromiográficos dos músculos mentual e orbicular inferior da boca em respiradores oronasais submetidas à massoterapia no músculo mentual. Métodos: experimento cego placebo controlado, com amostra de 19 respiradores oronasais, 1 homem e 18 mulheres, com média de idade (desvio-padrão) de 22,3 (2,63) anos, aleatoriamente dividida nos grupos controle e experimental, respectivamente com 7 e 12 voluntários. Apenas no grupo experimental foi aplicada mioterapia por meio de massagens, por três meses e em ambos os grupos foram coletados dados eletromiográficos no início e no final do tempo de tratamento nas condições de repouso e deglutição de água. A análise de variância foi aplicada para testar a existência de diferenças entre as médias e foi adotado o nível de significância de 5%. Resultados: a análise de variância revelou indícios de interação entre os efeitos de grupo e fase quando analisados os valores de Root Mean Square (RMS), tanto do músculo orbicular inferior como do músculo mentual. Como esperado, não foram encontrados indícios de diferenças significantes entre as médias das fases no grupo controle, entretanto, foram encontrados indícios de diferença significante no grupo experimental havendo redução das médias de RMS em ambos os músculos. O orbicular inferior, que na fase pré apresentava média (desvio padrão) de 202,10 (161,47) µV, apresentou valores de 131,49 (159,18) µV na fase pós, enquanto que o músculo mentual apresentou, respectivamente, nas fases pré e pós, média (desvio padrão) de 199,31 (279,77) µV e 114,58 (253,56) µV. Conclusão: tendo em vista a não detecção de efeito no grupo controle, atribui-se à massoterapia no músculo mentual a redução das médias de Root Mean Square dos músculos mentual e orbicular inferior da boca em respiradores oronasais.

Análisis fenoménico de la técnica neuromuscular funcional como tratamiento para el SAOS / Phenomenical Analysis of the Functional Neuromuscular Technique as a Treatment for OSA

Introducción: el objetivo de este estudio es develar si la técnica Neuromuscular Funcional (NMF) puede ser considerada como opción de tratamiento en el Síndrome de Apnea Obstructiva de Sueño (SAOS) y si se complementa con la Terapia Miofun-cional Orofacial o hace parte de ella.Métodos: la fenomenología trascendental de Husserl es el enfoque metodoló-gico que se adoptó para este estudio, siguiendo la ruta para su desarrollo: epojé, reducción trascendental fenomenológica y síntesis. El contenido real se obtuvo mediante dos entrevistas semiestructuradas, aplicadas a un informante clave que contó con los criterios de inclusión presupuestados. Resultados: en la primera etapa se identificaron 10 noesis y 266 noemas, que fue-ron relacionados entre sí; en la fase de reducción trascendental las noesis se redujeron a 5 y los noemas a 14. Análisis y discusión: el Método Chiavaro como fenómeno se decanta en las di-mensiones: (a) Enfoque Sistémico, (b) Técnica Neuromuscular Funcional y (c) Téc-nica Respiratoria. La prioridad del fenómeno NMF es la explicación de la alteración dentro del enfoque sistémico a partir de la lógica Función-Estructura-Función, de esta manera el SAOS se considera una manifestación de esas relaciones y como tal se le cataloga como adaptación o como función en disfunción.Conclusiones: la Técnica NMF hace parte de la neurorrehabilitación mientras que la TMO para intervenir el SAOS se inscribe en la fisiología del ejercicio

Introduction: the objective of this study is to reveal if the Functional Neuromuscu-lar technique (In Spanish: NMF) can be considered as a treatment option for OSA. Additionally, this paper seeks to assess if the aforementioned is derived from, a por-tion of or if it is complemented by Orofacial Myofunctional Therapy (OMT). Methods: Husserl's transcendental phenomenology is the methodological approach that was adopted for this study, following the path to its development: epoché, phenomenologi-cal transcendental reduction and synthesis. The actual content was obtained through two semi-structured interviews applied to a key informant who met the preconceived inclusion criteria.Results: in the first stage 10 noesis and 266 noems , which were related to each other, were identified; in the phase of transcendental reduction, the noesis were reduced to 5 and the noems to 14. Analysis and discussion: the Chiavaro Method as a phenomenon is composed of three dimensions: (a) Systemic Approach, (b) Functional Neuromuscular Technique and (c) Respi-ratory Technique. The priority of the NMF phenomenon is the explanation of the alteration within the systemic approach based on the Function-Structure-Function logic, ergo the OSA is considered a manifestation of these relationships and as such it is classified as adaptation or as a function in dysfunction.Conclusions: the NMF technique is a part of neurorehabilitation whilst OMT for the in-tervention of OSA is subscribed to the physiology of exercise.

Effectiveness and safety of Chinese herbal medicine for pediatric adenoid hypertrophy: A meta-analysis.

OBJECTIVE: Chinese herbal medicine has been gradually used to treat pediatric adenoid hypertrophy. This meta-analysis were conducted to evaluate the clinical efficacy and safety of Chinese herbal medicine in the treatment of pediatric adenoid hypertrophy. METHODS: Randomized controlled trials involving Chinese herbal medicine in the treatment of pediatric adenoid hypertrophy were identified from Cochrane Central Register of Controlled Trials, PubMed, EMBASE, Chinese National Knowledge Infrastructure, Chinese Biomedical Database, Wanfang Database and VIP Information Database. The methodological quality of trials was evaluated with Cochrane Handbook criteria, and the Cochrane Collaboration's Review Manager 5.3 software was used for Meta-analysis. RESULTS: A total of 13 valid articles involving 1038 patients were included. The meta-analysis showed that: Compared with western medicine treatment, Chinese herbal medicine significantly improved clinical efficacy (RR = 1.33, 95% CI [1.24,1.43]), and significantly decreased A/N ratio (MD = -0.04,95%CI [-0.05,-0.03]). Chinese herbal medicine also prominently improved the quality of life (MD = -4.77,95%CI [-8.35,-1.20]). Meanwhile, it dramatically improved snoring (MD = -0.46,95%CI [-0.62,-0.30]); mouth breathing (MD = -0.52,95%CI [-0.66,-0.39]); nasal obstruction (MD = -0.56,95%CI [-0.68,-0.45]). CONCLUSION: Chinese herbal medicine has good clinical efficacy and safety on pediatric adenoid hypertrophy, which need to be confirmed by high quality, multiple-centre, large sample randomized controlled trials.

Dental considerations and recommendations in Eisenmenger syndrome: A report of an unusual paediatric case.

BACKGROUND: Eisenmenger syndrome (ES) is a heart cyanotic condition characterised by elevated pulmonary vascular resistance and an intra-cardiac right-to-left shunting of blood through a systemic-to-pulmonary circulation connection. Affected children usually exhibit severe hypoxia, clubbing of fingers/toes, haemoptysis, anaemia, and organ damage. CASE REPORT: During autumn 2015, the patient and her parents arrived at the paediatric dentistry clinic. The patient presented with the main complaint of generalised inflamed gingival tissues, severely protruded upper incisors, and evident abnormal mouth breathing. TREATMENT: This was performed under local analgesia, rubber-dam isolation, and antimicrobial prophylaxis with amoxicillin (50 mg/kg). The patient's parents agreed to the treatment plan through a signed informed consent. This treatment consisted of the placement of pit and fissure sealants on the four permanent first molars (which included enamel preparation with fissurotomy burs), in-depth gingiva/dental frequent cleanings, local fluoride varnish applications, and an exhaustive programme of at-home oral hygiene (brushing, flossing, and chlorhexidine mouth rinses), including adequate nutrition. Gingivoplasty surgery to remove residual enlarged tissues was indicated for the near future. FOLLOW-UP: The child did not return to the clinic. When contacted, the parents reported that their daughter's systemic condition worsened significantly. She was confined to a bed at home under palliative care, with a life-span expectation of only a few months. CONCLUSION: Comprehensive dental care of children with ES requires careful consideration of their medical condition, and dental care delivery should be coordinated with the paediatric cardiologist. General analgesia should be considered only in strictly selected cases, due to the high peri-operative mortality reported.

A specific protocol of myo-functional therapy in children with Down syndrome. A pilot study.

In this article the authors propose a specific myofunctional therapy protocol for children with Down syndrome. For these patients, who usually present with atypical swallowing problems, mouth breathing and lip incompetence, the use of a myofunctional therapy protocol with specific exercises has been shown to improve orofacial and nasal functions. In addition to the functional results, such as the correction of the atypical swallowing, restoration of lip competence, breathing improvement and reduction of nasal rhinorrhea, there were also aesthetic results. This protocol can be useful to improve the quality of life of these patients.

Effect of orthodontic management and orofacial muscle training protocols on the correction of myofunctional and myoskeletal problems in developing dentition. A systematic review and meta-analysis.

The aim of this review was to evaluate available evidence on the effect of early orthodontic management and myofunctional treatment in the developing dentition children, on anterior open bite correction, as well as on normalization of patterns of mouth breathing, swallowing and tongue resting position and pressure. Electronic searches in MEDLINE, Cochrane and LILACS, without language restrictions were conducted. Additionally, unpublished literature was identified. Randomized controlled trials, or controlled clinical trials, comparing interventions applied to manage anterior open bite and other muscle functions such as breathing/swallowing pattern and tongue resting position and pressure, were considered. Quality assessment was based on the Cochrane Risk of Bias tool. Random effects meta-analyses were conducted to assess treatment effects. From the 265 initial search results, 15 articles were included in the review. Eight were randomized controlled trials (RCTs) and 7 were controlled clinical trials. Treatment outcomes comprised skeletal and dentoalveolar changes recorded cephalometrically, mouth posture and lip closure normalization, improvement of tongue resting position/pressure and modification of swallowing pattern. Quantitative synthesis was possible for only 2 of the included RCTs. There was no evidence to support bonded lingual spurs over banded fixed appliances for the correction of anterior open bite in mixed dentition children presenting nonnutritive oral habits at the onset of treatment (SMD: -0.03; 95%CI: -.81, 0.74; P = 0.94). Although early orthodontic management and myofunctional treatment in the deciduous and mixed dentition children appears to be a promising approach, the quality of the existing evidence is questionable.

Efetividade de um programa de terapia miofuncional no tratamento da respiração oral em indivíduos com má oclusão dentária: ensaio clínico / Effectiveness of a myofunctional therapy program in the treatment of mouth breathing in subjects with malocclusion: a clinical trial

A impossibilidade de respirar pelo nariz leva o indivíduo a desenvolver uma respiração oral que pode gerar modificações na postura lingual, labial e mandibular, bem como desarmonia dos tecidos moles, com consequente mudança na morfologia craniofacial, induzindo à má oclusão. Poucos trabalhos científicos descreveram as propostas terapêuticas empregadas ou utilizaram exames objetivos para mensurar a efetividade do tratamento miofuncional orofacial em casos de respiração oral. Sendo assim, esta pesquisa teve como objetivo verificar a efetividade de um programa miofuncional orofacial voltado ao tratamento da função respiratória em adultos com má oclusão dentária, considerando parâmetros respiratórios e a qualidade de vida em saúde oral. Participaram da pesquisa 13 indivíduos adultos em tratamento ortodôntico com má oclusão classe II, os quais foram divididos aleatoriamente em grupo experimental (GE) (n=9) e grupo controle (GC) (n=4). Foram aplicados os protocolos de qualidade de vida em saúde oral (OHIP-14) e de Sintomas Respiratórios. Além disto, foi feita a avaliação miofuncional da função respiratória, presente no protocolo MBGR, a qual envolve o tipo e modo respiratórios, fluxo nasal e possibilidade de uso nasal. Também foram avaliadas as medidas de tempo máximo de fonação (TMF) de /s/, pico do fluxo inspiratório nasal (peak-flow) e análise da medida da área de embaçamento da placa metálica, relacionada ao fluxo nasal expiratório. Foi possível observar que, após o processo terapêutico, os pacientes do GE apresentaram melhora estatisticamente significante quanto aos sintomas respiratórios (p<0,001), escore do Protocolo MBGR (p<0,001), tipo respiratório (p=0,041), modo respiratório (p=0,029), tempo máximo de fonação (p=0,002) e pico do fluxo inspiratório nasal (p=0,002), modificando os padrões que se encontravam alterados no momento pré-terapia. Já o GC permaneceu com os aspectos funcionais e sintomáticos alterados, apresentando piora quanto aos sintomas respiratórios (p=0,003) e TMF (p=0,013). Além disto, no período pré-terapia os grupos eram semelhantes entre si, sendo que após o tratamento, estes ficaram distintos no que diz respeito aos sintomas respiratórios (p=0,047), escore do protocolo MBGR (p=0,000), TMF (p=0,010) e pico do fluxo inspiratório nasal (p=0,001). Conclui-se assim, que após a aplicação do programa de terapia miofuncional orofacial para o tratamento da respiração oral, em indivíduos com má oclusão dentária, houve melhora dos parâmetros respiratórios no que diz respeito ao tipo e modo respiratório, bem como no pico inspiratório, aumento do TMF e diminuição dos sintomas respiratórios.(AU)

The inability to breathe through the nose leads the individual to develop oral breathing that can initiate changes in lingual, labial and mandibular posture, as well as soft tissue disharmony, with consequent changes in craniofacial morphology, leading to malocclusion. Few scientific papers have described the therapeutic proposals or used objective tests to measure the effectiveness of orofacial myofunctional therapy in cases of oral breathing. Thus, this research aimed to verify the effectiveness of an orofacial myofunctional program focused to the treatment of respiratory function in adults with malocclusion, considering respiratory parameters and quality of life in oral health. A total of 13 adult individuals undergoing orthodontic treatment with Class II malocclusion were randomly divided into experimental group (EG) (n=9) and control group (CG) (n=4). Oral health Impact Profile (OHIP-14) and Respiratory Symptoms protocols were applied. In addition, the myofunctional evaluation of the respiratory function, present in the MBGR protocol was performed, which involves respiratory type and mode, nasal flow and possibility of nasal use. The measures of maximum phonation time (MPT) of /s/, inspiratory peak of the nasal flow and analysis of the measurement of the haze area of the metal plate, related to the expiratory nasal flow were also evaluated. It was possible to observe that, after the therapeutic process, the EG patients had a statistically significant improvement in respiratory symptoms (p<0.001), MBGR Protocol (p<0.001), respiratory type (p=0.041), respiratory mode (p=0.029), maximal phonation time (p=0.002) and inspiratory peak flow (p=0.002), modifying patterns that were altered at the pre-therapy period. On the other hand, the CG remained with the functional and symptomatic aspects altered, presenting worsening of respiratory symptoms (p=0.003) and MPT (p=0.013). In addition, in the pre-therapy period, the groups were similar to each other, and after treatment, these were different concerning respiratory symptoms (p=0.047), MBGR Protocol (p=0.000), MPT (p=0.010) and inspiratory peak of the nasal flow (p=0.001). As conclusion, after the application of the orofacial myofunctional therapy program for the treatment of oral breathing, in individuals with malocclusion, there was an improvement in respiratory parameters regarding respiratory type and mode, as well as inspiratory peak, increased MPT and decreased respiratory symptoms.(AU)

Alteraciones orofaciales y electromiografía de superficie en trastornos del neurodesarrollo / Orofacial alterations and surface electromyography in neurodevelopmental disorders

Introducción. La electromiografía de superficie se ha convertido en una técnica muy utilizada para medir la actividad de distintos grupos musculares. Aunque la fiabilidad y validez de la técnica se discuten, existe un cuerpo importante de bibliografía científica que defiende su uso Objetivo. Presentar, mediante un estudio de caso, las dos utilidades básicas de la electromiografía de superficie: la medida de la actividad muscular orofacial y su empleo como biofeedback modulador de la propia actividad muscular. Caso clínico. Niña de 10 años con perfil facial dolicocefálico y prognático, mordida abierta anterior y mordida cruzada bilateral, oclusión clase II de Angle bilateral y deglución atípica con interposición lingual.

Tratamiento de luxación discal sin reducción: responsabilidad del odontopediatra / Treatment of disk displacement without reduction: the pediatric dentist´s responsibility

Actualmente, es frecuente la consulta por trastornos temporomandibulares (TTM) en la clínica odontopediátrica, siendo reconocida la múltiple causalidad de los mismos. Se presenta la resolución de una situación clínica de una paciente de 13 años de edad que acudió a la Cátedra de Odontología Integral Niños (OIN), presentando dolor muscular y articular del lado derecho, limitando la apertura bucal a 25 mm confortable y a 28 mm forzada, con desvío de la mandíbula hacia la izquierda. Refería haber sido atendida en una guardia médica el día anterior con bloqueo en apertura, luego de 8 meses de evolución, con síntomas de chasquido y doloir, sin haber realizado consulta alguna. Se indicó tratamiento sintomático y se solicitaron estudios complementarios. El diagnóstico fue de luxación discal sin reducción. Con la evaluación integral, se hallaron factores concomitantes, tales como maloclusión, hiperlaxitud, respiración bucal y parafunciones. En el abordaje terapéutico, se colocó un intermediario oclusal para reposicionamiento mandibular, se realizó tratamiento fonoaudiológico miofuncional y reeducación postural global (RPG). La paciente evolucionó favorablemente; a los 6 meses resolvió el ruido articular y al año estaba asintomática, con 37 mm de apertura, comenzando su tratamiento de ortodoncia y manteniendo controles durante 4 años. El compromiso de la familia y la participación de un equipo de trabajo, permitió la resolución integral del caso. El odontopediatra tiene la responsabilidad de alertar a padres y pacientes sobre factores de riesgo, diagnosticar TTM y orientar los tratamientos, involucrándose cuando corresponde su intervención, o derivando en forma oportuna...

Compromised Airway and Atypical Facial Growth in The Adult Patient: A Case Study in the Redirection of Facial Growth.

This case history is an adult patient with a compromised upper airway, soft tissue dysfunction, and atypicalfacial growth. The nasal deviation and enlarged turbinates resulted in mouth-breathing and soft tissue dysfunction. Atypical growth occurs when the biological balance between bone remodeling and positional displacement is disrupted Following septoplasty and turbinate reduction to reestablish nasal respiration and myofunctional therapy to retrain the muscles, the atypical growth was redirected to normal. The final result was an overall improvement in general health, esthetics, and well-being.

Mouth breathing, "nasal disuse," and pediatric sleep-disordered breathing.

BACKGROUND: Adenotonsillectomy (T&A) may not completely eliminate sleep-disordered breathing (SDB), and residual SDB can result in progressive worsening of abnormal breathing during sleep. Persistence of mouth breathing post-T&As plays a role in progressive worsening through an increase of upper airway resistance during sleep with secondary impact on orofacial growth. METHODS: Retrospective study on non-overweight and non-syndromic prepubertal children with SDB treated by T&A with pre- and post-surgery clinical and polysomnographic (PSG) evaluations including systematic monitoring of mouth breathing (initial cohort). All children with mouth breathing were then referred for myofunctional treatment (MFT), with clinical follow-up 6 months later and PSG 1 year post-surgery. Only a limited subgroup followed the recommendations to undergo MFT with subsequent PSG (follow-up subgroup). RESULTS: Sixty-four prepubertal children meeting inclusion criteria for the initial cohort were investigated. There was significant symptomatic improvement in all children post-T&A, but 26 children had residual SDB with an AHI > 1.5 events/hour and 35 children (including the previous 26) had evidence of "mouth breathing" during sleep as defined [minimum of 44 % and a maximum of 100 % of total sleep time, mean 69 ± 11 % "mouth breather" subgroup and mean 4 ± 3.9 %, range 0 and 10.3 % "non-mouth breathers"]. Eighteen children (follow-up cohort), all in the "mouth breathing" group, were investigated at 1 year follow-up with only nine having undergone 6 months of MFT. The non- MFT subjects were significantly worse than the MFT-treated cohort. MFT led to normalization of clinical and PSG findings. CONCLUSION: Assessment of mouth breathing during sleep should be systematically performed post-T&A and the persistence of mouth breathing should be treated with MFT.

Diagnóstico clínico de funciones orales: estudio comparativo de dos métodos de evaluación / CLinical diagnosis of oral functions: a comparative study of two evaluation methods

El diagnóstico funcional es fundamental en el tratamiento y pronóstico del paciente ortodóncico. Detectar deglución disfuncional o respiración bucal en etapa diagnóstica, nos permite arribar a un buen plan de tratamiento, que incluya la derivación al otorrinolaringólogoo a la fonoaudióloga en el caso de ser necesario, y favorece el pronóstico para lograr los objetivos propuestos y posibilitar la estabilidad post tratamiento. Objetivo: Comparar los resultados del diagnóstico funcional obtenidos por un mismo operador al mismo grupo de pacientes. Métodos: 22 pacientes, entre 16 y 30 años, pertenecientes a la Cátedra de Ortodoncia de la Facultad de Odontología de la Universidad deBuenos Aires. Se comparó utilizando dos mecanismos de diagnóstico: 1. Evaluación subjetiva y 2. Utilizando los test de respiración y de deglución como instrumento de evaluación. Resultados: con utilización del Test se registraron 18 pacientes con respiración nasal y 4 bucal, mientras que en la evaluación sinutilización se registraron 13 y 9 respectivamente, con diferencia estadísticamente significativa (P = 0.031). En la evaluación de la deglución con utilización del Test, de los 22 pacientes 3 presentaron deglución funcional, y 19 disfuncional, mientras que al evaluar sin utilización del Test, se registraron 8 con y 14 respectivamente, sin diferencia estadísticamente significativa, pero con un valor de p muycercano (P = 0.063). Conclusión: De los 22 pacientes, 6 no fueron correctamente diagnosticados al evaluarse su respiración y 5 no fueron correctamentediagnosticados al evaluarse su deglución, sin utilizar el Test por operadores con poca experiencia. La detección de disfunción respiratoriapresenta mayor dificultad que la de disfunción deglutoria...

Atypical swallowing: a review.

AIM: Atypical swallowing is a myofunctional problem consisting of an altered tongue position during the act of swallowing. High incidence in population, multifactorial etiology and the recurring connection with the presence of malocclusions made it a topic of strong interest and discussion in science. The purpose of this review is to illustrate the current orientation on the topic of atypical swallowing, trying in particular to answer two questions: 1) what kind of connection is there between atypical swallowing and malocclusion; 2) what kind of therapy should be used to solve it. METHODS: This review was conducted on the Medline database [www.ncbi.nim.nih.gov/pubmed] searching for the keywords "atypical swallowing" and "tongue thrust". We examined all the documents from the year 1990 onwards, excluding the ones about syndromic cases of the central motor system. RESULTS: The causal relation between the two problems seems to be biunique: some authors affirm that this oral habit starts as a compensation mechanism for a preexisting malocclusion (especially in case of open-bite); other texts show that it has a tendency to exacerbate cases of malocclusion; it is also proven that a non-physiological tongue thrust can negatively influence the progress of an ongoing orthodontic therapy. Thereby, the best therapeutic approach seems to be a multidisciplinary one: beside orthodontics, which is necessary to correct the malocclusion, it is essential to set up a myofunctional rehabilitation procedure to correct the oral habit, therefore granting long time permanent results. There is also proof of a substantial difference between the results obtained from early (deciduous or primary mixed dentition) or later treatments. CONCLUSION: The biunique causal relation between atypical swallowing and malocclusion suggests a multidisciplinary therapeutic approach, orthodontic and myofunctional, to temporarily solve both problems. An early diagnosis and a prompt intervention have a significantly positive influence on the therapy outcome.
