Prognostic Factors of Ossiculoplasty Using a Multivariate Analysis Based on the 2000 Japan Otological Society Guidelines

Seven hundred and eighty-four patients who underwent ossiculoplasty performed by a single surgeon were reviewed in this paper. We previously reported a similar study in another journal using the 1995 American Academy of Otolaryngology Head and Neck Surgery guidelines. In the present paper, hearing outcomes were estimated based on the 2000 Japan Otological Society guidelines. The prognostic factors were analyzed using a multivariate analysis with logistic regression. Hearing outcomes were successful in 517 patients (65.9%). Type III tympanoplasty, stapes with normal mobility, children, patients without cholesteatoma and ossiculoplasty with non-cartilaginous materials were significantly favorable predictive factors. A multivariate analysis should be performed to investigate prognostic factors of ossiculoplasty. Better knowledge of these predictive factors contributes to the surgeon's judgment and the information given to patients.
