Abstract
The aim of the present study is to report our results with cartilage "shield" tympanoplasty (CST) for total tympanic membrane perforations. A retrospective chart review of patients undergoing CST was performed in tertiary referral centers. One hundred and seventy-seven patients who had undergone CST were identified. Patients' age ranged from 7 to 74 (mean 35) years. The mean postoperative follow-up was 23 (range 6-73) months. The main outcome measures were Graft take, pre and postsurgery audiologic evaluation. Graft take was 97.2%. Three patients developed recurrent cholesteatomas, one an anterior pinhole perforation, and one a minimal graft anterior lateralization. The average pre and postoperative pure-tone air-bone gaps (PTA-ABG) were 32.06 ± 11.21 and 18.69 ± 10.53 dB, respectively. The overall average ABG improvement was 13.37 ± 9.34 dB. An overall postoperative ABG of 25 dB or less was achieved in 140 of the 177 patients (79.1%). Hearing improvement was statistically significant in all cases (p < 0.0001). Cartilage shield tympanoplasty is a very reliable procedure. Graft take is excellent and hearing improvement is significant.
