Summary
Superolateral temporomandibular joint dislocations, often from high-energy trauma, require prompt management to avoid surgery. Early physiotherapy is crucial to prevent temporomandibular joint ankylosis.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
Background:
- Superolateral temporomandibular joint (TMJ) dislocations are rare, typically resulting from high-energy trauma.
- These injuries are often accompanied by mandibular fractures.
Observation:
- A case report details a 35-year-old male with bilateral superolateral TMJ dislocations, bilateral condyle fractures, and a parasymphysis fracture after a road accident.
- Treatment involved external condyle reduction, open reduction, and internal fixation of the parasymphysis.
Findings:
- The patient achieved normal mouth opening within one month post-procedure.
- Prompt management is key to successful TMJ dislocation reduction, potentially avoiding surgery.
Implications:
- Temporomandibular joint ankylosis is a significant complication of these dislocations.
- Early initiation of physiotherapy is recommended to prevent TMJ ankylosis and ensure functional recovery.
