Patients in group A received a double layer tragal cartilage-perichondrium graft and those in group B received a temporal muscle fascia graft. The groups were compared with respect to the pre- and postoperative air-bone gap (ABG) and the graft success rate. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> The graft success rate was 98.5% (66\/67) in the Group A and 94.0% (63\/67) in the Group B at 6\u2009months, the difference wasn't statistically significant ( p\u2009=\u20090.362). However, the graft success rate was 97.0% (65\/67) in the Group A and 85.1% (57\/67) in the Group B at 12\u2009months, the difference was statistically significant ( p\u2009=\u20090.034). In addition, only one patient (1.49%) had small keratin pearls in the Group A, no patients developed cholesteatoma of middle ear in either group. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> The endoscopic double layer perichondrium-cartilage graft technique is feasible for repairing medium or larger perforations, it has a better long-term graft success rate and less operative time compared with the single layer fascia graft technique. However, long-term hearing outcomes were the same for the single and double layer closure techniques. <\/jats:p><\/jats:sec>","DOI":"10.1186\/s40463-020-00440-7","type":"journal-article","created":{"date-parts":[[2020,6,22]],"date-time":"2020-06-22T11:03:02Z","timestamp":1592823782000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":33,"title":["Endoscopic myringoplasty: Comparison of double layer cartilage-perichondrium graft and single fascia grafting"],"prefix":"10.1177","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1085-9033","authenticated-orcid":false,"given":"Zheng cai","family":"Lou","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, the affiliated Yiwu hospital of Wenzhou medical university (Yiwu central Hospital), 699 jiangdong road, 322000, Yiwu city, Zhejiang provice, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,1,1]]},"reference":[{"key":"bibr1-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-012-2329-4"},{"key":"bibr2-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1080\/00016489.2016.1195013"},{"key":"bibr3-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1186\/s40463-019-0335-x"},{"key":"bibr4-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.anorl.2019.05.001"},{"key":"bibr5-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1001\/jamaoto.2016.2114"},{"key":"bibr6-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1177\/0194599815599969"},{"key":"bibr7-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1002\/lary.27599"},{"key":"bibr8-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200205000-00007"},{"key":"bibr9-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1002\/lary.25904"},{"key":"bibr10-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-019-05579-2"},{"key":"bibr11-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215118000889"},{"key":"bibr12-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2014.02.007"},{"key":"bibr13-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1186\/s40463-019-0386-z"},{"issue":"19","key":"bibr14-s40463-020-00440-7","first-page":"30083","volume":"1808","author":"\u00d6zdamar K","year":"2019","journal-title":"Braz J Otorhinolaryngol"},{"key":"bibr15-s40463-020-00440-7","first-page":"274","volume":"95","author":"Bhattacharya SN","year":"2016","journal-title":"Ear Nose Throat J"},{"key":"bibr16-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1177\/000348941112000808"},{"key":"bibr17-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2018.09.003"},{"key":"bibr18-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215118000762"},{"key":"bibr19-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2018.01.002"},{"key":"bibr20-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1002\/lary.26451"},{"key":"bibr21-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1007\/s12070-011-0306-7"},{"key":"bibr22-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200108000-00027"},{"key":"bibr23-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000001080"},{"key":"bibr24-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1177\/0003489419843551"},{"key":"bibr25-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2017.08.006"},{"key":"bibr26-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1080\/00016489.2017.1354393"},{"key":"bibr27-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.3342\/ceo.2015.8.4.359"},{"key":"bibr28-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjorl.2015.12.009"},{"key":"bibr29-s40463-020-00440-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.otorri.2018.04.001"}],"container-title":["Journal of Otolaryngology - Head &amp;
