Abstract

BACKGROUND AND OBJECTIVES: The clinical association between painful temporomandibular disorder and orofacial myofunctional disorders is frequent and requires attention. The objective of this study was to describe a clinical case of painful temporomandibular disorder in association with orofacial myofunctional disorders that evidence the importance of dental and speech therapy approaches involving myofunctional orofacial limits, as well as to discuss whether the presence of orofacial myofunctional disorders can be a comorbidity that hinders the temporomandibular disorder management.

CASE REPORT: Female patient, 35 years old, complaining of pain in the orofacial region and joint noises during high amplitude mandibular movements for 17 years. She was diagnosed with myofascial pain and arthralgia (RDC/TMD) and orofacial myofunctional disorders (phonoarticulation with deviations and lingual interposition, atypical swallowing, oromandibular incoordination and mandibular hyperexcursion with eminence noise). Complementary tests (electromyography and electrovibratography) were performed in the pre- and post-treatment moments (1 year after). The treatment consisted of self-management and mindfulness orientations, stabilizing occlusal splint and speech therapy. After the treatment, there was an improvement in pain and mandibular range of motion, with consequent reduction of noise, better electromyographic balance and reduction of orofacial myofunctional disorders scores.

CONCLUSION: The case report has suggested that the presence of orofacial myofunctional disorders in association with painful temporomandibular disorder could interfere in the management of pain and the balance of the stomatognathic system because it seems to act as a worsening factor to the temporomandibular disorder signs and symptoms. In this sense, the importance of dental and speech therapy interventions in patients with orofacial myofunctional disorders as possible comorbidity to painful temporomandibular disorder is highlighted.

Resumo

JUSTIFICATIVA E OBJETIVOS: A associação clínica da disfunção temporomandibular dolorosa com distúrbios miofuncionais orofaciais é bastante frequente e requer atenção. O objetivo deste estudo foi mostrar um caso de disfunção temporomandibular dolorosa com associação de distúrbios miofuncionais orofaciais que evidenciou a importância do manuseio terapêutico odontológico e fonoaudiológico, com abordagens que envolveram limites miofuncionais orofaciais, bem como discutir se a presença de distúrbios miofuncionais orofaciais pode ser uma comorbidade que dificulta o manuseio da disfunção temporomandibular.

RELATO DO CASO: Paciente do sexo feminino, 35 anos, com queixa de dor na região orofacial e ruídos articulares durante movimentos mandibulares de grande amplitude há 17 anos. Diagnosticada com dor miofascial e artralgia (RDC/TMD) e distúrbios miofuncionais orofaciais (fonoarticulação com desvios e interposição lingual, deglutição atípica, descoordenação oromandibular e hiperexcursão mandibular com ruído de eminência). Foram realizados exames complementares (eletromiografia e eletrovibratografia) nos momentos pré e pós-tratamento (1 ano após). O tratamento consistiu de orientações de automanuseio e de atenção plena nas funções orofaciais (mindfulness), placa oclusal estabilizadora e terapia fonoaudiológica. Após o tratamento, houve melhora da dor e da amplitude dos movimentos mandibulares, com consequente redução dos ruídos, maior equilíbrio eletromiográfico dos músculos e redução dos escores dos distúrbios miofuncionais orofaciais.

CONCLUSÃO: O presente caso sugere que a presença dos distúrbios miofuncionais orofaciais em associação com a disfunção temporomandibular dolorosa pode interferir no manuseio da dor e no equilíbrio do sistema estomatognático, pois parece atuar como fator de piora dos sinais e sintomas da disfunção temporomandibular. Neste sentido, ressalta-se a importância de intervenções odontológicas e fonoaudiológicas em pacientes que apresentem os distúrbios miofuncionais orofaciais como possível comorbidade à disfunção temporomandibular dolorosa.
