ABSTRACT

OBJECTIVE:

To investigate whether there is any relationship between otological as well as vestibular symptoms, audiological findings and type of temporomandibular disorder (articular, muscular and mixed); and to check the distribution of the temporomandibular disorders (TMD) dysfunction degree in the research population.

METHODS:

A retrospective study involving 30 patients of both sexes, aged between 18 and 49 years old, diagnosed with TMD and dentofacial deformities, who were subject to clinical evaluation (muscle palpation, auscultation of temporomandibular joint during mandibular motion and measurement of jaw movement), audiological testing (pure tone audiometry and immittance testing) and two questionnaires, one on otological and vestibular symptoms and the other on TMD anamnesis. Based on both the anamnesis questionnaire and the clinical assessment, the subjects were divided according to the type and degree of TMD dysfunction (mild, moderate and severe), and compared regarding the occurrence of auditory signs and symptoms, vestibular symptoms and audiological findings according to TMD type.

RESULTS:

The anamnesis questionnaire demonstrated higher prevalence (83.33%) of severe TMD. Subjects with mixed TMD had more complaints about hypoacusis than those with muscular TMD (p < 0.05). The results showed no change in either audiological and immittance testing for all assessed individuals.

CONCLUSION:

Otological symptoms are present in subjects with TMD and dentofacial deformities, regardless of the classification of TMD (articular, muscular or mixed). Those with mixed TMD may have higher incidence of complaints about hypoacusis than subjects with muscular TMD. Further studies are needed to investigate the relationship between otological symptoms and the different types of TMD.
RESUMO

OBJETIVO:

investigar se há relação entre os sintomas otológicos, vestibulares, achados audiológicos e o tipo de disfunção temporomandibular (articular, muscular e misto), e verificar a distribuição do grau de disfunção da DTM nessa população.

MÉTODOS:

estudo retrospectivo, envolvendo 30 pacientes com deformidades dentofaciais diagnosticados com DTM, de ambos os sexos, entre 18 e 49 anos de idade, submetidos a avaliação clínica (palpação muscular, ausculta da articulação temporomandibular durante os movimentos mandibulares e mensuração da movimentação da mandíbula), exame audiológico (audiometria tonal limiar e imitanciometria) e a dois questionários, sendo um sobre sintomas otológicos e vestibulares e outro anamnético da DTM. A partir do questionário anamnético e da avaliação clínica, os sujeitos foram divididos conforme o tipo e o grau da disfunção da DTM (leve, moderado e severo), e comparados quanto à ocorrência dos sinais e sintomas auditivos, vestibulares e achados audiológicos, de acordo com o tipo de DTM.

RESULTADOS:

houve maior prevalência (83,33%) de DTM severa de acordo com questionário anamnético. Sujeitos com DTM mista apresentaram mais queixas de hipoacusia do que aqueles com DTM muscular (p < 0,05). Os resultados evidenciaram ausência de alterações nos exames audiológico e imitanciométrico para todos os indivíduos avaliados.

CONCLUSÃO:

sintomas auditivos estão presentes nos sujeitos com DTM e deformidades dentofaciais, independentemente da classificação da DTM (articular, muscular ou mista), e aqueles com DTM mista podem apresentar maior ocorrência de queixa de hipoacusia do que sujeitos com DTM muscular. Estudos futuros são necessários para investigar a relação entre a sintomatologia auditiva e os diversos tipos de DTM.
