A retrospective analysis of 85 EACC cases admitted to the Department of Otolaryngology, Renji Hospital, Shanghai Jiaotong University School of Medicine, from January 2016 to February 2021 was performed, followed by retrospective analysis of clinical data to explore the feasibility and clinical characteristics of all\u2010oral endoscopic EACC surgery. A total of 85 EACC patients (90 ears) with a mean age of 49.93 \u00b1 14.87 years were included in the study. According to Udayabhanu staging, 43 ears (47.78%) were stage I, 40 ears (44.44%) were stage II, and 7 ears (7.78%) were stage III. All patients underwent transendoscopic surgery.\n                    <jats:italic>Results<\/jats:italic>\n                    . 79 ears (87.78%) underwent endoscopic EACC resection alone (+external auditory canal tumor resection\/tympanostomy tube insertion), 9 ears (10%) underwent endoscopic EACC resection+tympanostomy+tympanoplasty, 1 ear (1.11%) underwent endoscopic EACC resection+tympanoplasty, and 2 ears (2.22%) underwent EACC resection+otolaryngotomy+tympanoplasty+auditory chain reconstruction endoscopically. Of these, 7 ears (7.78%) underwent auricular cartilage\u2010chondroplasty and 2 ears (2.22%) underwent auricular cartilage membrane repair. All patients were reviewed at 1 week, 2 weeks, 1 month, 3 months, 6 months, and 1 year postoperatively. One patient with stage II external auditory atresia had a recurrence after 6 months and underwent endoscopic ear surgery (ESS) again. One patient with stage 2 atresia recurred after 1 year and again underwent endoscopic ear surgery. The rest of the patients recovered well after the surgery, and the grafts healed well.\n                    <jats:italic>Conclusion<\/jats:italic>\n                    . EACC surgery through the external ear canal under a dedicated endoscope is a safe, reliable, and effective method. Patients with stage I and II external auditory canal cholesteatoma surgery under endoscopy have a rapid postoperative recovery with significant hearing improvement, and stage IIIA patients can also achieve good results under strict evaluation of indications.\n                  <\/jats:p>","DOI":"10.1155\/2022\/9190241","type":"journal-article","created":{"date-parts":[[2022,10,5]],"date-time":"2022-10-05T13:35:06Z","timestamp":1664976906000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["[Retracted] Clinical Analysis of 85 Cases of External Auditory Canal Cholesteatoma Surgery under Specialized Endoscopy"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3498-156X","authenticated-orcid":false,"given":"Yanan","family":"Guo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5994-6552","authenticated-orcid":false,"given":"Minfei","family":"Qian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiping","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1177-6117","authenticated-orcid":false,"given":"Hua","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,10,5]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000029631"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.36468\/pharmaceutical-sciences.spl.466"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000001972"},{"key":"e_1_2_8_4_2","first-page":"78","article-title":"Efficacy analysis of external auditory canal cholesteatoma under external otoendoscope on local anesthesia","volume":"10","author":"Zhengan Z.","year":"2018","journal-title":"China Continuing Medical Education"},{"key":"e_1_2_8_5_2","first-page":"21","article-title":"Clinical characteristics and treatment of 122 cases of external auditory canal cholesteatoma","volume":"18","author":"Chunxiang L.","year":"2020","journal-title":"Chinese Scientific Journal of Hearing and Speech Rehabilitation"},{"key":"e_1_2_8_6_2","first-page":"516","article-title":"Clinical characteristics and surgical treatment of 149 cases of external auditory canal cholesteatoma","volume":"34","author":"Zhe P.","year":"2020","journal-title":"Journal of Clinical Otorhinolaryngology Head and Neck Surgery"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000002087"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000003303"},{"key":"e_1_2_8_9_2","first-page":"798","article-title":"The application of autologous cartilago auriculae in posterior wall of external auditory canal reconstruction and tympanoplasty","volume":"30","author":"Dai G.
