Annular ligament reconstruction - a better technique in the surgical treatment of stapes fixation

Abstract

Reconstruction of the annular ligament using vein graft at the stapedotomy site gives a very good gain at low, frequencies as compared to Stapedotomy without a tissue seal It also protects against perilymph leak 1 0 8mm stapedotomy with a 0 4mm piston with 0 2 mm vein graft interposition is a better technique in the surgical treatment of stapes fixation The purpose of the present study is to determine the effectiveness of vein graft in sealing the oval window in small fenestra stapedotomy for stapedial otoselerosis We performed a prospective randomi ed trial in 80 cases of stapedial otoselerosis, 40 with and 40 without having a tissue seal at a tertiary referal center Ihere was a good air bone gap closure in both the groups There was a better gain in the lower frequencies in subjects where the vein graft was used
