The purpose of this study is to evaluate anatomical and audiological results after cartilage island tympanoplasty. A retrospective study was performed on 60 patients who underwent cartilage island tympanoplasty for repair of tympanic membrane from 2010 to 2014. Auditory function was analysed by performing preoperative and postoperative pure tone audiometry. Reviewed parameters were the graft uptake and change in pure tone audiometry air bone gap at each of four frequencies. Anatomical success and hearing assessment was done at 12 months. Postoperative pure-tone audiometric findings of the patients were obtained and hearing differences at 500, 1000, 2000, and 4000 Hz were assessed. Audiological outcome was assessed by gain in AB gap. The overall perforation closure was 88.33%. Residual perforation was seen in 7 cases. group. We did not find any statistical significance between site of perforation and graft uptake. Audiological improvement was 11.8 dB. There was improvement in the air-bone gap at all frequencies after surgery. The improvement in mean ABG was 9.9 dB at 500 Hz, 13.7 at 1000 Hz, 12.9 dB at 2000 Hz and 10.7 dB at 4000 Hz. These results are comparable to temporalis fascia graft. Cartilage tympanoplasty is a reliable and safe technique in the reconstruction of the tympanic membrane. Therefore, when indicated, a cartilage island graft can be used to reconstruct or strengthen tympanic membrane without fear of impairing hearing.
