BACKGROUND: There are very few studies analyzing the functional und audiological results of tympanoplasty type I using pure perichondrium. MATERIALS AND 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.
