Evaluation metrics included operation time, graft success rate, hearing gain, and complications at 24\u2009months postoperatively.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n The study included 103 patients with 103 ears. Follow-up loss occurred in 11 of 52 patients (21.2%) in the PCBI group and 13 of 51 patients (25.5%) in the PCOU group (\n P<\/jats:italic>\n \u2009=\u2009.773). The final analysis included 41 of 52 patients (78.9%) in the PCBI group and 38 of 51 patients (74.5%) in the PCOU group. The average operation time was significantly shorter in the PCBI group (31.2\u2009\u00b1\u20091.9\u2009min) compared to the PCOU group (52.8\u2009\u00b1\u20096.3\u2009min,\n P<\/jats:italic>\n \u2009<\u2009.001). At 24\u2009months postoperatively, the graft success rate was 82.9% (34 patients) in the PCBI group and 92.1% (35 patients) in the PCOU group (\n P<\/jats:italic>\n \u2009=\u2009.374). No significant group difference was noted in mean air\u2013bone gap (ABG) gain (\n P<\/jats:italic>\n \u2009=\u2009.759). High-resolution computed tomography (HRCT) demonstrated well-pneumatized mastoids and middle ears in both groups. Altered taste was reported in no PCBI group patients and 23.7% (9 patients) of the PCOU group patients (\n P<\/jats:italic>\n \u2009<\u2009.05). Graft cholesteatoma was found in 4.9% (two patients) in the PCBI group and 7.9% (three patients) in the PCOU group (\n P<\/jats:italic>\n \u2009=\u2009.930).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The endoscopic extended PCBI technique is safe and effective for repairing subtotal perforation. It avoids raising a tympanomeatal flap and demonstrates high long-term graft success with minimal complications.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/01455613231225614","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T05:59:33Z","timestamp":1704952773000},"page":"488-495","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of the Extended Perichondrium-Cartilage Butterfly Inlay Technique and Over-Underlay Technique for Repairing Subtotal Perforation: A 2-Year Follow-up Study"],"prefix":"10.1177","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7267-558X","authenticated-orcid":false,"given":"Chaowei","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Wenzhou Medical University Affiliated Yiwu Hospital, Yiwu City, Zhejiang Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,1,11]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/lary.27325"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/lio2.976"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199805000-00006"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215120000006"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/lary.25904"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/00016489.2020.1730949"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-019-05579-2"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2021.102978"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2018.07.001"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1177\/01455613211015439"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215123000968"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2020.102690"},{"key":"e_1_3_2_14_2","article-title":"Microscopic over-under versus medial tympanoplasty for larger tympanic membrane perforations","author":"Zhang X","unstructured":"Zhang X, Ji C, Li A, Xu Z, Zhang X.
