title: Chronic external otitis.
abstract: Chronic external otitis is probably a disease of mixed etiology; infection and hypersensitivity both play an important role. As such, these two components must be recognized and respected. Steroids are the mainstay of medical management. Antibiotics should be used cautiously and probably on an intermittent basis. The disease appears to be exacerbated by any manipulation of the canal, including aggressive cleansing. Medical therapy will slow the development of fibrosis in some cases, but it does not always prevent it. Once stenosis has progressed to the point that conductive hearing loss develops, surgery will restore hearing and prevent restenosis in at least 80% of cases.
