Abstract
The use of a homograft tympanic membrane with and without attached ossicles, staging the operation, and the use of sculptured homograft or autograft ossicles have improved the results in tympanoplasty. The indications and techniques of homograft tympanoplasty are described, and the results in 99 primary cases and 11 cases with repair of a mastoid cavity are given. The overall graft success rate was 86 per cent. In patients with an intact ossicular chain, the conductive loss was reduced to less than 20 dB. in 88 per cent. A hearing loss less than 20 dB. was obtained in 68 per cent with an intact stapes, in 77 per cent when the stapes superstructure was absent, and in 79 per cent in stapedectomy done at a second stage. The use of homograft material has provided the means for significantly improving the results in our patients who require tympanoplasty.
