title: [Ossiculoplasty with titanium prosthesis].
abstract: OBJECTIVE
  The goal of this study was to make a review of the patients who underwent ossicular chain reconstruction with titanium prosthesis during an eight-year period in our Department.
  
  
  METHODS
  A retrospective study was made on the ossiculoplasty cases over a period of eight years in a Public Hospital District. The information was extracted by clinical process consultation. Between 1999 and 2008, 124 ossiculoplasties using Kurz(®) titanium prosthesis for chronic otitis media were performed (78 partial ossicular chain reconstructions and 46 total ossicular chain reconstructions). The single stage, staged and revision ossicular chain reconstruction were included in the analysis. All patients had a minimum of 6 month postoperative follow up (mean 3 years and 4 months). Comparisons of preoperative and postoperative pure tone averages were performed. Air-bone gap and implant extrusion rates were measured. The success of the reconstruction was defined as a postoperative air-bone gap (ABG) of 20 dB or better.
  
  
  RESULTS
  Successful ossiculoplasty was obtained in 73,1% of partial ossicular reconstruction reconstructions and 30,4% of total ossicular chain reconstructions (P<.05). The postoperative pure-tone average air-bone gaps was 16 dB in partial reconstructions and 26,7 dB in total reconstructions (P<.05). There were five cases of prosthesis extrusion.
  
  
  CONCLUSIONS
  The majority of the ossiculoplasties improved satisfactorily the hearing status. There was no difference in hearing results in one-stage and two-stage partial ossicular chain reconstruction, but there were better hearing results in the cases of two-stage total ossicular chain reconstruction.
