Area of Science:

  • Orthopedics
  • Trauma Surgery
  • Maxillofacial Surgery

Background:

  • Temporomandibular joint (TMJ) dislocations are uncommon, accounting for 3% of all joint dislocations.
  • Anterior dislocation of the mandibular condyle is the typical presentation.
  • Posterior dislocation of the TMJ without fracture is exceptionally rare.

Observation:

  • A young male patient sustained facial trauma.
  • The patient presented with a posterior dislocation of the intact mandibular condyle.
  • Clinical symptoms, diagnostic imaging, and treatment were documented.

Findings:

  • The case report details a rare instance of posterior TMJ dislocation.
  • The mandibular condyle was displaced posteriorly without associated fracture.
