In this presentation, Dr. James L. Sheehy discusses two surgical problems of the external auditory canal. Diffuse exostosis, which is bilateral and symmetrical, is very common, but it doesn't usually require surgery. When it does, however, the surgery can be difficult. An osteoma, or isolated exostosis, is a unilateral lesion and always requires simple surgery, but it is not common. Dr. Sheehy demonstrates these two procedures using slides and with video footage from the Ear Institute's Temporal Bone Dissection courses.
