The success rate of external auditory canal stenosis surgery is relatively high, above 90%. It is usually necessary to make an incision in the ear, extending outward to the tragus, bypassing the foot of the helix and upward. Separate the skin from the bone surface, and then smooth the bone of the ear canal with a bone drill to widen it. After satisfaction, disinfect and sew the incision at the helix and tragus, and fill the ear with iodoform gauze. If the postoperative packing is not in place, it will cause granulation hyperplasia in the ear canal, thus causing stenosis again.
