A Comparative Prospective Study to Evaluate Outcomes of Ossiculoplasty using Autograft Versus Synthetic Graft

Chronic Otitis Media is the most common cause of hearing impairment with ear discharge with which patients report to any otologist. The aim of management in such cases is to provide a safe ear and restore the hearing by Tympanoplasty. Many materials have been used for ossicular reconstruction, including both biological and synthetic materials. Minimally destroyed ossicle can be utilized for Ossiculoplasty while in case of complete destruction of ossicles, synthetic materials may be used such as teflon, titanium, hydroxyapatite etc. To evaluate the outcome of Ossiculoplasty using autograft versus synthetic graft. A prospective study done using non-probability convenience method of sampling involving a group of 50 patients were subjected to Tympanoplasty with Ossiculoplasty. Intra operative decision was taken on the type of graft to be used for Ossiculoplasty and the patients were divided into two equal groups, A (autograft) and B (synthetic graft) of 25 each. The patients were thereafter evaluated post surgery at periodic intervals of 3, 6 and 12 months. The improvement in hearing following surgery was significant (AB gap < 20 dB) in the range of 72% in Group A to 84% in Group B of patients 12 months after surgery. Also there was a 37% change in AC in Group A as compared to 40% in Group B, demonstrating marginally better improvement in hearing with synthetic graft as compared to autograft. The patients have significant improvement in hearing thresholds after ossiculoplasty with both autograft and synthetic graft. Teflon is an excellent alternative for ossiculoplasty when autologous incus is not available for use due to disease.
