Bilateral temporomandibular joint dislocation

Case contributed by Dr Henry Knipe


Post anaesthetic. Clinically dislocated. X-ray confirmation pre-reduction.

Patient Data

Age: 30
Gender: Male

Both mandibular condyles lie anteriorly to the articular tubercle of the temporal bone. This is suggestive of bilateral TMJ dislocation.

Case Discussion

Temporomandibular joint (TMJ) dislocation occurs when there is anterior displacement of the mandibular condyles out of the manidbular fossa past the articular articular eminence, this must be manually reduced. TMJ subluxation is a similar displacement but is self-reducing. 

The TMJs were successfully enlocated by the oral-maxillofacial surgeons.
