title: [Functional and audiological results of tympanoplasty type I using pure perichondrial grafts].
abstract: BACKGROUND
  There are very few studies analyzing the functional und audiological results of tympanoplasty type I using pure perichondrium.
  
  
  METHODS
  Data of 80 randomly selected patients, who had tympanoplasty surgery between 1998 and 2008 with pure perichondrium were evaluated retrospectively. Average postoperative follow-up was 9 months. The preoperative- and postoperative status of tympanic membrane, air-bone gap (ABG) and influence of perforation size and perforation etiology on closure rate served as study parameters.
  
  
  RESULTS
  The closure rate for tympanoplasty type I with pure perichondrium was 85% and the mean ABG reduction was 10.8±7.22 dB. Size and etiology of the perforation had no influence on operative results.
  
  
  CONCLUSIONS
  Concerning closure rates pure perichondrium is very suitable for repairing tympanic membrane defects. Postoperative audiological results can be compared to other transplants, such as temporal fascia or combined cartilage-perichondrium grafts and the intraoperative handling and positioning seem to be more comfortable.
