Temporomandibular joint alterations: two clinical case-reports of bifid condyle and temporomandibular joint ankylosis

ABSTRACT The etiology of alterations of the temporomandibular joint, such as ankylosis and bifid condyle, comprises several causes including trauma. However, otological infections cannot be overlooked as a probable cause of alterations of the temporomandibular joint, because the proximity between the external auditory canal and the temporomandibular joint facilitates the spread of infection in the region. This article presents a case-report of a patient with bifid condyle of the temporomandibular joint, in which the patient had no history of facial trauma, but had suffered recurrent otitis infections during her childhood. In parallel, a second case-report is described of temporomandibular joint ankylosis in a 12-year-old patient with a history of facial trauma during her childhood. The purpose of this study was to highlight and emphasize the importance of early diagnosis of temporomandibular joint disorders to avoid the development of facial asymmetries, restore function, esthetics, and the psychological state of the patient.
