The protrusion of articular soft-tissue from the temporomandibular joint (TMJ) into the external ear in the absence of trauma, neoplasm or inflammation is rare. We present below a Nigerian adult male with retrodiscal herniation of soft-tissues of the TMJ into the external auditory meatus through a persistent foramen of Huschke. We are not aware of any reports of this developmental defect or its prevalence in the Nigerian medical literature. Therefore, this case is presented to heighten the index of suspicion of physicians when managing patients with otorrhea and otalgia; which is often primarily diagnosed or misdiagnosed as otitis externa. This will help avoid complications associated with the anomaly, some of which could be very serious.
