This study was undertaken to see the usefulness of columella materials and the methods of ossicular reconstruction in modified type IV tympanoplasty. We devised a columella composed of autogenous bone and temporalis fascia. The remaining auditory ossicles or cortex of the temporal bone sculptured suitably was employed as columella material. Temporalis fascia was trimmed to a round sheet, 0.4 cm in diameter and glued to a bone piece with ARON ALPHA. This columella was set on the oval window fossa or foot plate of the stapes, which neither fall down nor slip off readily because of its stability, even by washing the wound. This technique was performed in 7 cases of cholesteatoma and in 5 cases of chronic suppurative otitis media. There were no operative failure cases such as perforation of the tympanic membrane or displacement of the columella. Postoperative hearing improved to within 40 dB in 4 of the 12 cases (33%).
