The audiological and take results of perichondrium attached cartilage island graft in tympanoplasty: PACIT

Cartilage is one of the most preferable grafts for tympanoplasty (TPL). The anatomical and audiological results and take rates of perichondrium attached cartilage island graft in tympanoplasty (PACIT) are presented herein. One hundred ninety four ears of 191 patients (108 male, 83 female) were evaluated retrospectively in terms of the type of surgery, graft take rate and hearing results. Type I, II, and III TPL were performed in 127 (65.46%), 45 (23.20%), and 22 (11.34%) ears, respectively. The overall mean preoperative pure tone average-air bone gaps (PTA-ABGs) for TPL types were 33.74 ± 9.60, 52.58 ± 9.07, and 56.58 ± 10.27 dB HL, respectively; postoperative mean values for TPL groups were 18.55 ± 9.25, 31.21 ± 4.36, and 44.84 ± 12.45 dB HL. Postoperative hearing results showed an improvement (≥ 10 dB) in 76.81% of ears with a mean gain of 20 dB HL (range 10-40 dB). However, 19.07% of ears showed no change (< 10, ≥ 0 dB) in hearing, and hearing worsened in 4.12% of ears (< 0 dB) postoperatively. Overall, graft take was 91.24% at least 13 months (mean 68.64) after surgery with a graft failure rate of 8.76%. Graft take was successful in TPL groups. Postoperative PTA-ABG results demonstrated significant improvement. The long-term eligibility of perichondrium attached cartilage island graft in TPL is emphasised with this study.
