Results of revision tympanoplasty for chronic non-cholesteatomatous otitis media

There is no evidence of increased risk of graft failure in re-tympanoplasty cases when compared to primary tympanoplasty operations. Hearing results depend on structural changes in the middle ear (ossicular abnormalities and tympanoscerosis) which in revision cases are found more often. No differences were found between fascia, perichondrum or cartilage-perichondrium grafts in terms of graft healing and hearing results.
