“…Due to the physiological curvature of the external auditory canal or scar stenosis, some relatively hidden lesions (e.g., tympanic cavity and mastoid process) are not clearly identified during microscopic surgery, and there are certain blind spots in the field of view. In contrast, microscopic surgery, in order to remove the hidden lesions present in a wide range of lesions and to preserve important structures, is inevitably achieved at the cost of destroying more bony structures; however, this cost, although we now have many reconstruction methods to repair the relevant structures, is still fraught with difficulties, and the repair does not guarantee the integrity of the original anatomical structures [ 13 , 14 ].…”

Objective. To investigate the clinical characteristics, surgical experience, and surgical outcomes of external auditory canal cholesteatoma (EACC) surgery under endoscopic otolaryngoscopy. Methods. 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-oral endoscopic EACC surgery. A total of 85 EACC patients (90 ears) with a mean age of 49.93 ± 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. Results. 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-chondroplasty 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. Conclusion. 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.

“…Based on previous literature and our FIGURE 4 Scatter plot of child age vs. the minimal diameter at the narrowest segment of the ear canal. 13,19,22,[25][26][27][28][29]. We also propose a simple flowchart to facilitate the decision-making process of choosing between EES and MES for pediatric CMEC (Figure 5).…”

IntroductionSurgical removal is widely employed in children with congenital middle ear cholesteatoma (CMEC). Here, we report the surgical outcomes of CMEC removal via endoscopic ear surgery (EES) and microscopic ear surgery (MES) in children.MethodsChildren with CMEC who underwent preoperative medical history inquiry, hearing test, endoscopic evaluation, and radiology imaging before receiving EES or MES were included. Postoperative audiological outcomes and recurrence rates were collected.ResultsSeventeen children (20 ears) with stage II-IV CMEC were included. Of those, 11 ears (55.0%) underwent EES, and 9 ears (45.0%) underwent MES. The follow-up time was 35 ± 13.5 months. One child in the EES group with stage III CMEC had a recurrence during the follow-up period. In the EES group, the average minimum diameter of the external auditory canal on the affected side was 5.8 mm (4.3–8.0 mm). No linear association was found between age and the minimum diameter of the external auditory canal.DiscussionEES is a promising treatment option for children with early-stage CMEC because of its low recurrence rate and minimally invasive nature. The minimum diameter of the external auditory canal on the affected side should be meticulously examined when performing EES in children.
