Aims: To analyze and compare the outcomes of ossiculoplasty in terms of hearing results and graft take-up rates, using autograft incus and titanium middle ear prosthesis in patients with ossicular chain erosion. Study Design: Randomized clinical trial. Materials and Methods: Patients between 10 and 60 years of age with a history of chronic ear discharge with moderate conductive deafness (>40 dB HL) were included in the study. The patients underwent detailed ENT examination followed by audiological and radiological assessment of temporal bone and those patients with evidence of ossicular erosion were subjected to ossiculoplasty with autologous incus (group I) or titanium prosthesis (group II) randomly. The patients were followed up after 3 months to analyze the functional and anatomical results. Results: A total of 24 patients with ossicular chain defect were included in the study, of whom 12 patients underwent ossiculoplasty with autograft incus and 12 with titanium prosthesis. Postoperative hearing evaluation by pure tone audiogram was done after 3 months, which showed successful hearing improvement in 58% of cases with autologous incus as compared to 33% cases with titanium prosthesis. Complications and extrusion rate were also higher in patients with titanium prosthesis. Conclusion: Hearing results after ossiculoplasty with autologous incus were significantly better compared with those after titanium prosthesis. Also, complications and extrusion rate were higher in patients with titanium prosthesis. This indicates that ossiculoplasty with autoincus offers better hearing results with minimal complications and extrusion rates as compared to titanium prosthesis.
