The study was carried out to find out the ideal graft material by comparing the audiological outcome after tympanoplasty by using three different types of grafts: tragal cartilage, temporalis fascia, and cartilage island. The study included ninety patients, 30 in each group of tympanoplasty using temporalis fascia, tragal cartilage, and cartilage island by underlay technique. The patients were followed up for a period of 6 months, and hearing outcomes were compared by using pure-tone audiometry. The outcomes were analyzed in terms of residual perforation (graft uptake) and preoperative and postoperative hearing air–bone gap. Using statistical analysis, the cartilage island graft was found to be far superior to temporalis fascia and tragal cartilage grafts. The hearing outcome was improved in all groups but was statistically significant in the cartilage island group when compared to both the other groups (p <0.001). Hearing results of temporalis tympanoplasty and tragal cartilage tympanoplasty were similar and statistically insignificant (p = 1). Graft uptake of cartilage island was the best with no failures in our limited series. Graft uptake of temporalis fascia and tragal cartilage were also good, with slightly better results in the temporalis fascia group than in the tragal cartilage graft group (statistically insignificant p = 1). Overall, cartilage island graft is much superior to either the temporalis fascia or the whole cartilage graft as far as both graft uptake and hearing results are concerned. Although it is a more skillful job as far as the technique is concerned, the superior results make it worth following by every otology surgeon.
