Sample technique: Non probability purposive sample with random allocation to the two study groups using random number table. Method: Group I underwent underlay myringoplasty and group II was managed by over under myringoplasty. Result: In group I, 25(83.3%) patients had a full take of the graft at the 3-month follow-up. In group II, 27(90%) patients had a full take of the graft at the 3-month follow-up. These patients did not develop severe graft lateralization, infection or blunting (p 0.7). In group I, the hearing improvement or the decrease in air bone gap is by 11±7.2db while in group II, the improvement of hearing or decrease in air bone gap is by 12.2±7db (p 0.52). Conclusion: There were high success rate of graft up take and considerable hearing improvement in both techniques of myringoplasty.
