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.
