@entity75 , with meninges ( @entity3976 ) or without meninges ( @entity3976 ), following mastoidectomy is rare. However, the seriousness of the complication and the potential for its prevention necessitate periodic review and emphasis. In this study, 6 @entity1 with small iatrogenic @entity130 during mastoidectomy, 1 @entity1 with postoperative large @entity3976 , and 2 @entity1 with three spontaneous @entity3976 are reviewed. These cases, and the literature, support the following: 1. A @entity130 is necessary for herniation. 2. If the @entity2443 remains intact, a @entity3976 results with the potential for @entity5173 into the middle ear and recurrent @entity693 . 3. If the @entity2443 is not intact, an @entity3976 results which presents predominantly as a mass without a @entity5173 . 4. The dura and @entity2443 may be torn during mastoidectomy, resulting in an immediate @entity5173 that can go easily unrecognized. Taking time to carefully inspect any area of dural exposure obviates this oversight. 5. A satisfactory technique of tegmen and dural- @entity2443 repair in these ten cases is described.
