Abstract

The purpose of this study is to investigate the middle ear condition, surgical method and suitable material for optimal hearing gain in the middle ear cholesteatoma surgery. One thousand and thirty six cases of ossiculoplasty in patients suffering from chronic otitis media with cholesteatoma at the university hospitals in Korea from November 1984 to July 1996 were included in this retrospective study. Sixty two per cent of cases were successful according to the success criterion of a post-operative air-bone gap of >or= 30dB, 33.4 percent according to >or= 20dB, and 12.6 percent according to >or= 10dB. Good prognostic factors in the middle ear condition were healthy middle ear mucosa, patent eustachian tube orifice, and presence of superstructure of stapes. Two staged ossiculoplasty showed better result than one staged ossiculoplasty. There was no statistical difference of the hearing improvement between the open cavity mastoidectomy and the intact canal wall mastoidectomy techniques. Favorable materials for ossicular reconstruction were in decending order, polycel, ossicle, cartilage, and hydroxylapatite.
