Fracture of the tympanic plate with soft tissue extension into the auditory canal resulting from an unfavorable chewing experience.
We present a case where a patient sustained a tympanic plate fracture of the right side while chewing a sandwich. Intense pain with temporomandibular joint (TMJ) symptoms such as restrained painful mouth opening and functional pain in full occlusion followed the incident and the fracture was diagnosed after ocular and CT-examination of the right external auditory canal. Non-ruptured soft tissue could be seen protruding into the external auditory canal and the size of the mass changed during movement of the TMJ. Treatment was not needed to resolve the situation and at 3-year follow-up the patient has no clinical symptoms.
