Temporomandibular joint disc disfigurement and abnormal thickening of the posterior band.

Temporomandibular joint (TMJ) disc disfigurement is a common finding associated with various stages of disc displacement and injury. However, in most cases, the clinical diagnosis of disc displacement without reduction may not be readily apparent due to either a delay in patient presentation or lack of early imaging of the disc. The case of a 22-year-old woman with a history of TMJ disorder, seeking treatment for a history of unilateral posterior open bite and bilateral jaw pain, is described.
