Background: Situation of incus erosion is common while performing tympanoplasties for cases of chronic otitis media. As none of the available techniques is said to be gold standard, a cost effective and easily available partial ossicular replacement prosthesis is employed and the postoperative hearing outcome is presented.

Objectives: To assess the hearing results of ossiculoplasty using partial ossicular replacement prosthesis during tympanoplasty.

Methodology: A descriptive cross-sectional study was carried out in a tertiary referral  hospital of Nepal from June 2018 to September 2019. Twenty-eight consecutive patients who underwent tympanoplasty for chronic otitis media (inactive/mucosal) with incudostapedial discontinuity were operated using polytetrafluoroethylene partial ossicular replacement prosthesis without removing the incus. Pure tone averages, air-bone gap and air conduction gain were calculated pre and post-operatively.

Results: There was no extrusion of prosthesis. The post-operative air-bone gap less than 20 dB was achieved in 23 (77%) cases. All the patients had post-operative air-bone gaps of ?25dB. There were no major complications.

Conclusion: Polytetrafluoroethylene partial ossicular replacement prosthesis is a safe, reliable and efficient alternative for ossiculoplasty during tympanoplasty surgery.
