Abstract

Herniation of the temporomandibular joint (TMJ) into the external auditory canal is rare as TMJ and external auditory canal are separated by an anterior bony wall of external auditory canal. The bony defect of the anterior external auditory canal can be caused by trauma, otologic procedure, neoplasm, inflammation and a rare congenital bony defect. Conservative treatment is available if the severity of the symptom is mild or asymptomatic. However, surgical procedure is considered if the patient experiences severe distress. There have been no reported cases of surgical-related complications and recurrence during postoperative follow-up period. Herein we report the very first case of foreign body prolapse involving herniation from TMJ extending into the external auditory canal.
