Magnetic resonance imaging findings of temporomandibular joint soft tissue changes in type V and VI condylar injuries.

Purpose: The objective of this study was to describe the incidence of acute temporomandibular joint (TMJ) soft tissue lesions associated with the occurrence of type V (high condylar fractures with dislocation) and type VI condylar fractures (condylar head fractures).

Patients And Methods: The study comprised 11 consecutive patients, who were assigned a diagnosis of a uni- or bilateral type V or type VI condylar fracture. Bilateral sagittal and coronal magnetic resonance (MR) images were obtained immediately after injury to establish the presence or absence of disc disruption, capsular tear, retrodiskal tissue tear, and hemarthrosis.
