Hearing Outcome in Ossiculoplasty With Autologous Incus and Teflon Prosthesis in Chronic Otitis Media: a Comparative Study.

To observe and compare the functional outcome in term of hearing gain in ossiculoplasty with autologous incus and Teflon made TORP/PORP in cases of chronic otitis media (COM) with ossicular disruption. 60 patients of COM between age of 11-50 years who had ossicular disruption were included in the study. They were divided into two groups of 30 patients/ group: group 1 included those patients who had mucosal COM and group 2 included those who had squamous COM. They were further subdivided into 3 subgroups each as per the ossiculoplasty material used. Pre-operative pure tone audiometry (PTA) was done. They all were followed-up at 3 months after surgery and at that time PTA was done. Pre-and post-operative hearing was compared and hearing improvement was calculated in term of air-bone gap (ABG). Out of 60 cases, 16 cases marked as failure of ossicular reconstruction as post-operative A-B gap was > 30 dB. Among these 16 cases, 7 were those patients whom ossiculoplasty was done using autologous incus and in rest 9 patients PORP/TORP was used. Success rate of ossiculoplasty using refashioned incus was 76.66% whereas Teflon TORP/PORP had success rate of 70.00%. We conclude that hearing improvement after ossiculoplasty with autologous incus is better as compare with that obtained by Teflon TORP/PORP. Also, it is a cost-effective method.
