ABSTRACT
The American Academy of Orofacial Pain (AAOP) defines ankylosis of the temporomandibular joint (TMJ) as a restriction of movements due to intracapsular fibrous adhesions, fibrous changes in capsular ligaments (fibrous-ankylosis) and osseous mass formation resulting in the fusion of the articular components (osseous-ankylosis). The clinical features of the fibrous-ankylosis are severely limited mouth-opening capacity (limited range of motion during the opening), usually no pain and no joint sounds, marked deflection to the affected side and marked limitation of movement to the contralateral side. A variety of factors may cause TMJ ankylosis, such as trauma, local and systemic inflammatory conditions, neoplasms and TMJ infection. Rheumatoid arthritis (RA) is one of the systemic inflammatory conditions that affect the TMJ and can cause ankylosis. The aim of this study is to present a case of a female patient diagnosed with bilateral asymptomatic fibrous-ankylosis of the TMJ associated with asymptomatic rheumatoid arthritis. This case illustrates the importance of a comprehensive clinical examination and correct diagnosis of an unusual condition causing severe mouth opening limitation.
RESUMO
A Academia Americana de Dor Orofacial (AAOP) define anquilose da Articulação Temporomandibular (ATM) como restrição dos movimentos devido à adesão fibrosa intracapsular, alterações fibrosas nos ligamentos capsulares (fibroanquilose) e formação de massa óssea resultando na fusão dos componentes articulares (anquilose óssea). As características clínicas da Fibroanquilose são capacidade severamente limitada de abertura bucal geralmente sem dor e sem ruídos articulares, com marcada deflexão para o lado afetado e marcada limitação de movimentos para o lado contralateral. Uma variedade de fatores pode causar anquilose da ATM, como trauma, condições inflamatórias locais e/ou sistêmicas, neoplasias e infecção na ATM. A artrite reumatóide (AR) é uma dessas condições sistêmicas inflamatórias que pode afetar a ATM e causar anquilose. O objetivo desse estudo é apresentar um caso de uma paciente, diagnosticada com Fibroanquilose da ATM bilateral e assintomática associada à AR. Esse caso ilustra a importância de um exame clínico bem realizado com exames complementares pode levar a um diagnóstico correto de Fibroanquilose da ATM e da importância do diagnóstico diferencial em casos de abertura bucal restrita.
