## TL;DR

This study explores whether orofacial myofunctional symptoms are linked to clinical signs in adults with sleep breathing disorders, finding a moderate negative correlation in chewing-related issues.

## Contribution

The study identifies a moderate negative correlation between chewing-related signs and symptoms in adults with sleep breathing disorders.

## Key findings

- A moderate negative correlation was found between masticatory signs and symptoms in adults with sleep breathing disorders.
- No correlation was observed for breathing and swallowing functions.
- Common symptoms included unilateral chewing and swallowing difficulties.

## Abstract

to verify whether orofacial myofunctional symptoms are related to findings from orofacial myofunctional clinical assessment in adults sleeping breathing disorders (SBD).

observational study; 15 adults, with a mean age of 43 years and diagnosed with primary snoring or OSA by polysomnography; evaluated using the Orofacial Myofunctional Assessment Protocol MBGR, including the Clinical History Protocol to assess symptoms, and the Clinical Examination Protocol to identify signs, considering tests of mobility of lips, tongue, soft palate and jaw; tone of lips, tongue, cheeks and chin; respiratory mode; chewing; and swallowing solids and liquids. For the correlation between signs and symptoms, Spearman's Correlation Coefficient, considering p<0.05 statistically significant, was used.

The main orofacial myofunctional complaints were related to chewing (use of only one side during chewing and the need to drink liquids during meals), and swallowing (choking and residue after swallowing). In the orofacial myofunctional assessment, there was a greater frequency of alterations in tongue tone; lip mobility; unilateral chewing pattern with increased speed and chewing inefficiency; swallowing with excessive contraction of the perioral muscles, associated head movement and presence of residue in the oral cavity. The correlation between the scores of orofacial myofunctional signs and symptoms showed significance only between the aspects related to the chewing function (p=0.034), being moderate and inversely proportional (r=-0.548).

a moderate negative correlation was found between masticatory signs and symptoms in adults with SBD, and no correlation was observed for breathing and swallowing functions.

verificar se sintomas miofuncionais orofaciais se relacionam com achados da avaliação clínica miofuncional orofacial em adultos com distúrbio respiratório do sono (DRS).

estudo observacional; 15 adultos com média de idade de 43 anos e com diagnóstico de ronco primário ou AOS por polissonografia; submetidos ao Protocolo de Avaliação Miofuncional Orofacial MBGR, incluindo o Protocolo de História Clínica para levantamento dos sintomas, e o Protocolo de Exame Clínico para a identificação dos sinais, considerando as provas de mobilidade de lábios, língua, véu palatino e mandíbula; tonicidade de lábios, língua, bochechas e mento; modo respiratório; mastigação; deglutição de sólido e líquido. Para a correlação entre sinais e sintomas foi utilizado o Coeficiente de Correlação de Spearman, considerando estatisticamente significante p<0,05.

os principais sintomas miofuncionais orofaciais foram relacionados à mastigação (uso de apenas um lado durante a mastigação e necessidade de ingestão de líquidos), e à deglutição (engasgos e resíduos após a deglutição). Na avaliação miofuncional orofacial houve maior frequência de alteração para tonicidade de língua; mobilidade de lábios; padrão mastigatório unilateral com velocidade aumentada e ineficiência mastigatória; deglutição com contração excessiva da musculatura perioral, movimento de cabeça associado e resíduos na cavidade oral. A correlação entre os escores de sinais e sintomas miofuncionais orofaciais apontou significância apenas entre os aspectos relacionados à função de mastigação, sendo moderada e inversamente proporcional.

foi encontrada correlação moderada negativa entre sinais e sintomas mastigatórios em adultos com DRS, não tendo sido observada correlação para as funções de respiração e deglutição.
