Autogenous ossicles in ossiculoplasty: the auditory outcomes and prognostic factors / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To explore the auditory outcomes and prognostic factors in ossiculoplasty using autogenous ossicles. METHODS A retrospective review was performed in 126 patients with cholesteatoma or chronic otitis media, who admitted to the Department of Otolaryngology in Jingzhou hospital affiliated to Tongji medical college from January 2014 to July 2016, and underwent canal wall-down tympanoplasty (CWDT) with ossiculoplasty using autogenous ossicles in a single stage. The postoperative complication and hearing thresholds were analyzed after 12 months' follow-up. RESULTS The rate of dry ear was 96.5％. We had not found any extrusion of prosthesis. There was no one with postoperative retraction pocket or recurrence of cholestatoma during the follow-up. Auditory outcomes showed air conduction threshold improved from (52.7±7.4)dB to (39.0±9.1)dB after operation, while the air-bone gaps improved from(27.4±6.9)dB to (20.8±6.2)dB. Postoperative outcomes were considered successful, if the postoperative air-bone gap was <20 dB. The successful hearing was achieved in 88 patients (69.8％). Prognostic factors were analyzed using multivariate analysis with logistic regression. And we found the presence of the stapes and the malleus handle was significantly favorable predictive factors. All the patients recovered well without severe complication. CONCLUSION Autogenous ossicles is very valuable in ossiculoplasty. The present stapes and malleus handle are important factors for the auditory outcomes in ossiculoplasty.
