  • Abstract
  • Look Inside

 The experiences of stapedectomy in 2 cases of tympanosclerosis and one case (2 ears) of congenital oval window defect are reported with a reviw of literature. Various problems related to the stapedectomy are discussed.

 Since tympanosclerosis may be accompanied by active infection causing sclelotic changes of the mucous membrane, it is advisable to remove the stapes in a two-stage operations.

 In all cases the operation after stapedectomy was a modified type 4 tympanoplasty. This was attained by placing the tytnpanic membrane (or skin graft) on the vein (or fascia) that sealed the oval window. All cases showed a recovery of conversational hearing level.

 No postperative complication has been observed, so far, following this double-graft procedure. However, for a proper evaluation of this method a longer follow ups are by all means a necessity.
