TMJ dislocation is an unusual complication of TEE. We report a case of bilateral TMJ dislocation in a 70-year-old man prior to direct current cardioversion for atrial fibrillation. Shortly after TEE, the patient complained of bilateral facial pain and difficulty with speech; his mouth was left permanently open with his chin lowered and thrown forward ( Fig. 1 ). The examination found an empty glenoid fossa of the TMJ in both sides. The diagnosis of TMJ dislocation was established and the reduction was performed by maxillofacial surgery without sedation.
