Single osteomas can be removed surgically via one of two routes, depending on their location. Those arising lateral to the isthmus of the external auditory canal can be removed under local anesthesia using a transmeatal approach; those arising medial to the isthmus should be removed under general anesthesia using a postauricular approach.

A 71-year-old man was sent to the Otology and Neurotology service at the University of Louisville with a history of a mass in the left external auditory canal (EAC). He stated that the mass had been present since his early 20s but had become symptomatic over the preceding few years. He complained of intermittent drainage and earaches associated with a mixed hearing loss.
