title: [Therapeutic effect of ossicular reconstruction with bioceramic or porous macromolecular polyethylene partial ossicular replacement prosthesis in patients with tympanosclerosis].
abstract: OBJECTIVE
  To evaluate the effect of ossicular reconstruction with partial ossicular replacement prosthesis (PORP) in patients with tympanosclerosis.
  
  
  METHODS
  The data of 31 cases of tympanosclerosis treated between 1992 and 2009 were reviewed. Of the 31 patients, 17 (17 ears) underwent ossicular reconstruction with porous macromolecular polyethylene PORP, and 14 (14 ears) with bioceramic PORP. All the patients were followed up for 3-24 months.
  
  
  RESULTS
  Significant improvement was found in postoperative speech frequency (500, 1000, 2000 Hz) pure tone average (PTA) and air-bone gap (ABG) (P < 0.05) after the treatments without statistically significant differences between the two groups (P > 0.05).
  
  
  CONCLUSIONS
  Porous macromolecular polyethylene and bioceramic are valuable ossicular prosthesis for tympanosclerosis.
