A 27-year-old man presented with pain in his throat after a generalized seizure. He had a 2-year history of nighttime seizures and wore dental prosthetics. Upon awakening after the seizure, the patient complained of chest pain and pain in his throat and coughed up some blood. He could not find his front teeth. Physical examination revealed subcutaneous emphysema around his trachea. X-ray of the cervical spine showed the prosthetic device in his esophagus (figure). Endoscopic examination showed no perforation of the esophagus. The prosthetic was removed and the patient resumed his antiepileptic drugs.
