Cartilage is of the materials that can be used to enhance graft. This study was done to evaluate hearing after homograft cartilage tympanoplasty.Methods: This clinical trial study conducted in Alzahra hospital in Isfahan, Iran. 40 patients with recurrent perforation, retraction pocket and cholestatoma were operated by homograft cartilage tympanoplasty method. The audiometery was down for all of the patients before and after tympanoplasty. All patients were followed up for at least 6 months. The data was analyzed by SPSS software using Student’s t, paired t and ANOVA tests.Findings: After at least 6 months of surgery, there was not any case of perforation or cholestatoma recurrency. The change in range of 500, 1000, 2000 and 4000 frequency was 5.9 ± 1.9, 5.9 ± 1.6, 4.6 ± 1.6 and 3.8 ± 1.6 respectively and the difference between before and after surgery was statistically significant. In the other word, audiometry revealed improvement at all frequencies. Conclusion: Homograft cartilage tympanoplasty prevents perforation, cholestatoma and retraction paket recurancy after surgery. Hearing results were good.
