Tympanoplasty

Abstract

The study comprises of 164 ears of modified radical mastoidectomy with tympanoplasty performed as one stage operation in our hospital. The ears were followed up for 5 years. Out of these 164 ears, postaural approach was performed in 90 ears and endaural with removal of bone from inside out in 74 ears. Tympanoplasty was performed in all the cases as one stage operation with incus transposition in 42 cases, autogenous cortical bone columella between malleus handle and stapes head in 80 cases, between stapes footplate and graft material in 30 cases and preserved homograft ossicles between stapes footplate and graft in 12 cases. Dry ears with graft take up occurred in 92% cases within 6 to 10 weeks. No recurrence of cholesteatoma was seen. Ossiculoplasty using autogenous cortical bone columellas resulted in somewhat greater improvement in the post operative airbone gap than ossiculoplasty with auto or homograft ossicles. Similarly the post operative gap improved more with an intact stapes superstructure than in ears where the stapes superstructure was absent. The use of a cortical bone can be recommended in cases where the patient’s own ossicles are affected by disease and cannot be used.
