This report describes the clinical and radiographic findings together with surgical management of temporomandibular joint contents herniation through the tympanic plate of the external auditory canal. Two patients are reported. A review of the literature is presented, including a brief discussion of the embryological development of the external auditory canal. Excluding infection, trauma or neoplasm, the defect in the tympanic plate of the external auditory canal represents a developmental aberration with failure of the foramen of Huschke to close during development.A pre-auricular approach with insertion and fixation of an onlay polyethylene implant to prevent prolapse of the peri-articular tissues into the ear canal is presented and described.

AbstractObjectives:We describe a rare case of spontaneous temporomandibular joint herniation into the external auditory canal, and we also review the presentation, aetiology and management of such cases.Case report:An 87-year-old woman presented with a four-month history of left-sided otorrhoea and otalgia. Examination revealed a soft, polypoid mass in the left ear canal. When the patient opened her mouth the lesion disappeared. Subsequent computed tomographic imaging of the patient's temporal bones confirmed an 8.6 mm defect in the antero-inferior portion of the left ear canal, with herniation of retrodiscal soft tissues.Conclusion:The external auditory canal is intimately related to the temporomandibular joint, separated only by its bony anterior wall. Neoplasm, trauma or inflammation in this area can result in displacement of the temporomandibular joint into the ear canal; however, spontaneous herniation is rare. Persistence of the primitive foramen of Huschke can result in dehiscence of the anterior canal wall, allowing articular tissue to prolapse into the ear canal. Surgical closure of these defects is known to be effective in ameliorating symptomatic cases.

Synovial chondromatosis is a benign disease which most commonly appears in large joints and only rarely affects the temporomandibular joint. The diagnosis is quite difficult due to the fact that a large swelling in the preauricular area and the radiographic findings may be misdiagnosed as other benign or malignant diseases. We report an unusual case of intra- and extracapsular chondromatosis of 25 osteochondral loose bodies in the right temporomandibular joint.

Previous authors have shown that soft tissue can present in the external auditory canal via a patent foramen of Huschke. One case represented a patient with psoriatic arthritis and a polyp in the external auditory canal. Typically, neoplastic, inflammatory, or degenerative lesions of the temporomandibular joint do not present in the external auditory canal. We present a patient with rheumatoid arthritis of the temporomandibular joint and soft tissue herniation into the external auditory canal. The case, and a discussion of possible causes, are presented.
