Using bone cement in re-bridging incudostapedial joint

Abstract

Objective: to evaluate the hearing outcomes of using ionomeric bone cement in re-bridging incudostapedial joint discontinuity. Methods: This study included 50 patients who had ossiculoplasty using ionomeric bone cement for re-bridging of incudostapedial joint. There pre and post-operative audiologic outcomes were evaluated and reviewed by using pure tone audiometry averages and the air bone gap values with a follow up period of one year. Results: 42 patients (84%) had a post-operative air bone gap less than 20 dB following one year of surgery. The pre and post-operative mean of pure tune averages were 50.04±7.28 and 32.74±7.07 respectively (P value<0.01). The pre and post-operative mean of air bone gap were 36.56±6.41 and 17.60±5.77 respectively which was statistically significant (P value<0.01). Conclusion: using of ionomeric bone cement is a good grafting material in incudostapedial re-bridging ossiculoplasty being cost effective, easy applicable and biocompatible and give a satisfactory hearing outcome in selected patients.
