This study was undertaken to find the prevalence of perforated graft in underlay and Pop-in Technique Myringoplasty.&#x0D;\nMethods: This descriptive cross-sectional study was done at Manipal teaching hospital, Pokhara, Nepal and comprises of 86 patients between January 2014 and June 2015. Patients undergoing Underlay Trans-canal approach by tympano-meatal flap elevation and Trans-canal, Trans-tympanic pop-in technique were included. Sample size calculation was done and convenient sampling method was applied. Point estimate at 95% CI was done for binary data along with frequency and proportion. The descriptive statistical analysis was done.&#x0D;\nResults: The prevalence of perforated graft was 15 (17.4%) at 95% Confidence Interval (39.75-60.25%).In underlay technique there were 8 (18.60 %) perforation and 35 (81.39%) were intact while in pop-intechnique there were 7 (16.27%) perforation and 36 (83.72%) were intact. The postoperative meanPure Tone Average (PTA) of underlay was 9.53 and pop-in was 8.31. The mean Pure Tone Average(PTA) gain after underlay technique was 16.095 and pop in technique was 16.87.&#x0D;\nConclusions: Trans-tympanic pop-in myringoplasty gives similar hearing &amp; graft uptake results when compared with tympano-meatal flap method of underlay myringoplasty done by trans-canal.<\/jats:p>","DOI":"10.31729\/jnma.4709","type":"journal-article","created":{"date-parts":[[2020,2,24]],"date-time":"2020-02-24T20:26:33Z","timestamp":1582575993000},"source":"Crossref","is-referenced-by-count":0,"title":["Prevalence of Perforated Graft in Underlay and Pop-in Technique Myringoplasty"],"prefix":"10.31729","volume":"57","author":[{"given":"Bhuwan Raj","family":"Pandey","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Poonam","family":"KC","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16919","published-online":{"date-parts":[[2019,12,31]]},"container-title":["Journal of Nepal Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/www.jnma.com.np\/jnma\/index.php\/jnma\/article\/download\/4709\/3013","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.jnma.com.np\/jnma\/index.php\/jnma\/article\/download\/4709\/3013","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,2,24]],"date-time":"2020-02-24T20:26:41Z","timestamp":1582576001000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jnma.com.np\/jnma\/index.php\/jnma\/article\/view\/4709"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12,31]]},"references-count":0,"journal-issue":{"issue":"220","published-online":{"date-parts":[[2019,12,31]]}},"URL":"https:\/\/doi.org\/10.31729\/jnma.4709","relation":{},"ISSN":["1815-672X","0028-2715"],"issn-type":[{"value":"1815-672X","type":"electronic"},{"value":"0028-2715","type":"print"}],"subject":[],"published":{"date-parts":[[2019,12,31]]}}}
