title: [Clinical application of titanium ossicular prostheses in intact canal wall tympanoplasty with mastoidectomy].
abstract: OBJECTIVE
  To evaluate the effects of intact canal wall tympanoplasty with mastoidectomy (ICWT) with titanium ossicular prostheses.
  
  
  METHODS
  A retrospective review was performed on 31 patients who underwent ICWT from 2008 to 2011. Patients' postoperative hearing results and complication rates were evaluated based on different types of ossicular prosthesis: partial ossicular replacement prosthesis (PORP), total ossicular replacement prosthesis (TORP).
  
  
  RESULTS
  The total effectiveness was 87.1%. No prosthesis was extruded. There was no significant difference in postoperative hearing results (average postoperative gain and ABG) between the two prostheses. In the low frequency (0.5 kHz), significant difference in ABG was found.
  
  
  CONCLUSIONS
  No significant difference in postoperative hearing results was found between PORP and TORP, which could be useful materials for tympanoplasty and obviously improve the hearing of otitis media patients after operation. As for the low incidence of postoperative complications in our short-term study, long-term follow-up visit is necessary.
