Abstract

Objectives: To determine which method underlay or overlay has higher results in graft uptake in Tympanoplasty. Study Design: It was experimental study. Setting: it was carried out at ENT Department of Benazir Bhutto Hospital, Rawalpindi. Period: One year from March 2017 to February 2018. Material and Methods: It consisted of a total of 27 patients presenting with chronic otitis media with dry perforation. Two groups of patients were made. Group A had 14 members who undergone underlay technique while the 13 patients in group B undergone overlay technique. Comparison was made on basis of successful graft uptake the main criteria of which was absence of lateralization, atelectasis, blunting or formation of retraction pockets by the end of 6 weeks of follow up. Result: Out of the 27 surgeries, 70.37% of the Myringoplasties were successful. The percent graft uptake came out to be 61.5% with overlay and 78.5% with underlay myringoplasty. In 15 out of the 27 surgeries temporalis fascia was used with a graft uptake rate of 80%, the 12 grafts taken from tragus had a graft uptake rate of 58.33%. Conclusion: Underlay myringoplasty technique has higher results than overlay myringoplasty technique.
