Results of revision mastoidectomy.

Conclusions. Successful canal wall down (CWD) mastoidectomy requires removal of all diseased air cells, lowering of the facial ridge to the mastoid segment of the facial nerve, complete removal of the lateral epitympanic wall, and amputation of the mastoid tip. Additionally, the inferior canal wall should be lowered to adequately expose the hypotympanum, which allows a smooth transition into the mastoid cavity. An adequate meatoplasty is also necessary. Closed supratubal recess should be opened, anulus and tympanic membrane remnant should be removed in CWD cases. Revision mastoidectomy has a high success rate in obtaining a dry and epithelialized ear. Objective. This study reports revision mastoidectomy results and indicates factors that must receive attention in chronic otitis media surgery to produce less revision surgery. Patients and methods. Thirty-five patients who underwent revision mastoidectomy with or without cholesteatoma between 2005 and 2008 were analyzed retrospectively. Patients who had rev...
