title: Functional results of Plastipore prostheses for middle ear ossicular chain reconstruction.
abstract: OBJECTIVE
  Assessment of plastipore prostheses for middle ear ossicular chain reconstruction. Hearing results with total and partial Plastipore ossicular replacement prostheses (TORP and PORP) were evaluated in open- and closed-cavity operations.
  
  
  METHODS
  A retrospective review of 237 patients who underwent operation for chronic ear disease as well as ossiculoplasty with plastipore prostheses. In order to assess the functional results, only 156 of 237 patients were included in the study. Follow-up ranged from 6 to 46 months.
  
  
  METHODS
  Canal wall up and canal wall down operations were performed. Either TORP or PORP ossiculoplasty was performed in each operation. An airbone gap closure to within 20 dB was considered successful.
  
  
  RESULTS
  With TORPs, the airbone gap closure to within 20 dB was achieved in 43.1%, and similar results were obtained with PORPs in 63.3%. In canal wall down and canal wall up operations, the success rates were 55.8% and 55.7%, respectively. The best results were obtained with PORPs in canal wall down operations, with a success rate of 82%. The extrusion rate of the prostheses was 4.2%.
  
  
  CONCLUSIONS
  Hearing results of PORPs are better than TORPs. In canal wall up and canal wall down operations similar hearing results are obtained. PORP ossiculoplasty in a canal wall down operation yields the most favorable hearing result.
