Herniation of the temporomandibular joint (TMJ) into the external auditory canal is rare asTMJ and external auditory canal are separated by an anterior bony wall of external auditorycanal. The bony defect of the anterior external auditory canal can be caused by trauma, otologicprocedure, neoplasm, inflammation and a rare congenital bony defect. Conservativetreatment is available if the severity of the symptom is mild or asymptomatic. However, surgicalprocedure is considered if the patient experiences severe distress. There have been no reportedcases of surgical-related complications and recurrence during postoperative follow-upperiod. Herein we report the very first case of foreign body prolapse involving herniation fromTMJ extending into the external auditory canal.
