Summary

Objective

To assess the efficiency of ossiculoplasty procedures with the Kurz titanium ossicular prosthesis and evaluate prognostic factors for the functional results.

Methods

Retrospective chart reviews were performed for ossiculoplasty involving Kurz titanium prostheses between 2006 and 2009 in the ENT Head and Neck Department of the hôpital Nord, Marseille, France.

Results

The population studied was 70 patients, with 37 procedures using the partial (PORP) and 33 the total ossicular replacement prosthesis (TORP). Mean follow-up was 9 months. Pre- and postoperative audiological parameters on four frequency averages (0.5, 1, 2, and 3kHz) were compared according to AAO-HNS guidelines. A postoperative air-bone gap (ABG)≤20dB was obtained in 71.43% of the patients (86.49% for PORP, and 54.55% for TORP). The mean change in ABG was 12.45dB in cholesteatomatous otitis versus 13.41dB in non-cholesteatomatous otitis.
