Dislocated Jaw (TMJ Dislocation): Reduction, Recovery & When Surgery Is Needed

Acute Management

• Reduction: Usually performed by a clinician (ER, oral surgeon, ENT) within minutes using intraoral or extraoral techniques (e.g., Hippocratic, wrist-pivot). Sedation/analgesia often used.
• Post-Reduction Immobilization: Soft diet, avoid wide opening, sometimes a Barton bandage or cervical collar for 1–3 days (evidence for prolonged immobilization is weak).
• Pain/Inflammation: NSAIDs, ice, muscle relaxants if spasm.

Recovery Timeline

• Simple dislocation (no fracture): Most recover fully in 2–6 weeks. Recurrence risk is ~10–20% (higher with ligamentous laxity).
• Persistent pain/dysfunction: May last months; PT for TMJ mobilization, posture, muscle retraining helps.

Indications for Surgery

• Recurrent/chronic dislocation failing conservative care.
• Associated fractures (condylar, mandibular).
• Failed closed reduction.
• Procedures: Eminectomy, meniscectomy, arthroscopic plication, total joint replacement (rare).

Prevention of Recurrence

• Avoid extreme opening (yawning, large bites, dental procedures without support).
• TMJ exercises to strengthen coordination.
• Night guard if bruxism contributes.
