Titanium middle ear prostheses are effective for ossicular reconstruction in chronic ear disease, achieving good hearing outcomes. Extrusion rates were low, with no significant difference when combined with cholesteatoma surgery.

Area of Science:

  • Otolaryngology
  • Biomaterials Engineering
  • Audiology

Background:

  • Chronic ear disease often necessitates ossicular reconstruction.
  • Titanium prostheses offer a biocompatible option for middle ear reconstruction.

Purpose of the Study:

  • To evaluate the efficacy of titanium prostheses for ossicular reconstruction in chronic ear disease.
  • To assess hearing outcomes, complications, and extrusion rates associated with titanium prostheses.

Main Methods:

  • Retrospective study of 73 patients undergoing ossicular reconstruction with titanium prostheses (PORP and TORP).
  • Data collected from two Scandinavian tertiary otology referral centers between 1999 and 2004.
  • Preoperative and postoperative pure tone averages (PTA) and air-bone gap (ABG) were compared.

Main Results:

  • 77% of patients achieved a postoperative air-bone gap (ABG) of ≤20 dB.
  • Overall mean PTA improved by 20.6 dB, with an ABG improvement of 19.3 dB.
  • The overall extrusion rate was 5%, with no difference found between procedures with or without concurrent cholesteatoma surgery.

Conclusions:

  • Titanium prostheses are effective, easy to handle, and safe implants for ossicular chain reconstruction.
  • Hearing results were favorable, with low complication and extrusion rates.
  • Specific combinations of prosthesis type and surgical approach impacted hearing outcomes.
