Polycel prosthesis is effective for ossiculoplasty, improving hearing outcomes. Healthy middle ear mucosa and intact stapes superstructure are key factors for successful hearing improvement in ossicular chain reconstruction.

Area of Science:

  • Otolaryngology
  • Biomaterials in Surgery
  • Hearing Reconstruction

Background:

  • Alloplasts are increasingly utilized in otologic surgery.
  • Ossiculoplasty aims to restore hearing by reconstructing the ossicular chain.

Purpose of the Study:

  • To evaluate hearing results after ossiculoplasty using Polycel prosthesis.
  • To identify prognostic factors for hearing improvement in ossicular reconstruction.

Main Methods:

  • Retrospective review of 188 patients undergoing ossicular chain reconstruction with Polycel prosthesis.
  • Postoperative air-bone gap (ABG) measured over 12 months.
  • Analysis of factors including middle ear mucosa, stapes superstructure, cholesteatoma, and surgical technique.

Main Results:

  • 84% of patients achieved an ABG of <=30 dB.
  • 51.1% achieved an ABG of <=20 dB.
  • 11.7% achieved an ABG of <=10 dB.

Conclusions:

  • Polycel is an effective material for ossiculoplasty.
  • Healthy middle ear mucosa and presence of stapes superstructure are favorable prognostic indicators for hearing gain.
