Hearing Gain with Tailor-made Polyethylene Strut in Total Stapedectomy

Abstract

Objective: To study audiometric changes after total stapedectomy with tailor-made polyethylene strut. Methods: A retrospective analysis of preoperative and postoperative hearing results. One hundred and ninety- eight patients underwent total stapedectomy during 2009-2014. Stapedectomy was performed with tailor-made polyethylene strut prosthesis on vein or perichondrium graft over oval window. Changes of preoperative and postoperative pure tone average (PTA) were calculated from 4 frequencies after stapedectomy. Results: Ninety percent success rate in the air-bone gap closure within 10 dB after stapedectomy. Conclusion: Tailor-made polyethylene strut prosthesis is a cheap and cost-effective prosthesis, which is an alternative option for surgeons instead of the commercial prosthesis.
