[Repair of the attic wall by a mastoid osteofibrous graft]

Closed techniques for the management of cholesteatomas often require repair of the external auditory meatus. Small losses of substance around the tympanic membrane or in the attic wall can be repaired by a mastoid cortical autograft. The originality of the procedure described on the basis of the various operative stages is based above all on the preservation of an osteoperiosteal fringe contiguous with the bone graft used. The value of the technique lies in availability of the graft at the operative site and the ease of its insertion into the defect requiring repair.
