Soft tissue lesion of the ear canal – Now you see it, now you don’t

Spontaneous herniation of the temporomandibular joint along a bony defect in the external auditory canal is an uncommon condition that may lead to otologic symptoms. A 43-year-old gentleman presented with otalgia and an external auditory canal soft tissue lesion, which flattens upon opening of the jaw. Computed tomography scan of the temporal region confirmed the presence of a soft tissue lesion that herniated through an external auditory canal wall defect. This condition should be included in the differential diagnoses of an external auditory canal mass, despite infrequently encountered. It is important to inspect the external auditory canal during movement of the jaw when a soft tissue lesion is noted, so as not to miss this diagnosis.
