Abstract:
Unilateral temporomandibular joint (TMJ) dislocation is a rare condition often triggered by yawning, vomiting, or other activities involving wide opening of the mouth, resulting from the forward movement of the condylar head. This case report highlights a longstanding unilateral TMJ dislocation managed by the single injection of local anesthetics into the deep temporal and masseteric nerve peripheries, alleviating muscle spasm and pain to restore TMJ function.
