INTRAOPERATIVE FINDINGS IN REVISION MASTOID SURGERY

While the main goals of surgery for chronic otitis media are elimination of disease and improving hearing, sometimes persistent drainage continues and mandates revision surgery. the aim of this study is to assess the intraoperative findings during revision mastoid surgery and to ascertain the preventable factors. a total of 88 revision mastoidectomies performed from 1996 to 2000 at amiralam university hospital in tehran were reviewed. the most frequent findings during surgery were retained infected air cells, cholesteatoma and mucosal inflammation/granulation tissue. the overall success of revision surgery was 97.5%. (providing a dry and safe ear) while hearing preservation is possible in most cases, improvement of hearing is a difficult goal in these patients. with careful preoperative assessment and performing a complete surgical approach, the primary goal of revision mastoid surgery is obtainable in most patients
