According to this study, the success rate of tympanoplasty in graft uptake by underlay technique was 86% and by overlay technique was 70%. Hearing results were significantly different between overlay and underlay groups. Closure of Air Bone Gap with in 0 - 20 dB in underlay group was 86% while in overlay group it was 69%.
