Objective: The objective was to determine which material, among autologous cartilage, autologous incus and partial ossicular replacement prosthesis (PORP), gives better postoperative hearing result in ossiculoplasty. Study Design: Nonrandomized prospective cohort (longitudinal study). Settings: Tertiary referral center. Materials and Methods: Patients were selected from outpatients department with the clinical diagnosis of chronic suppurative otitis media with cholesteatoma or granulation tissue. Patients underwent necessary preoperative investigations including pure tone audiometry (PTA). Total 67 patients were selected for this study, among them 12 patients did not fit the selection criteria and 5 patients lost during follow-up. Hence, total 50 patients were taken in the study group. Intervention: Ossiculoplasty with cartilage, incus and PORP after modified radical mastoidectomy. Main Outcome Measure: Hearing results were measured by PTA-air bone gap (PTA-ABG) after 6 months of operation. Results: Selecting the criteria <20 dB ABG as success when stapes superstructure is present, cartilage has 60% success rate, incus has 73.68%, and PORP has 56.25% success. Extrusion rate of different prosthesis shows, PORP has 25%, cartilage has 20% extrusion. Incus has the lowest (5.26%) extrusion rate. Conclusion: Among the ossiculoplasty materials, autologous incus gives best postoperative hearing gain and lowest extrusion rate.
