Acquired atresia of the external ear canal is a narrowing of the external ear canal (EAC) that appears obstructed by fibrous tissue or bone tissue. Acquired atresia has two different phases: wet and dry stage. Computed tomography (CT) scan may show a scan where soft tissue fills EAC. Treatment may be medical and/or surgical. The surgical treatment of choice is represented by canaloplasty with a skin-free flap. To our knowledge, no article has reported data on the analysis of vascularization of acquired atresia of the external ear canal and vascularization of skin flap during follow-up with narrow-band imaging. This study evaluated patients suffering from acquired atresia of the external auditory duct, treated surgically in our Department of Organi di Senso of Sapienza University, from 2017 to 2020. All patients underwent: anamnestic collection, physical examination, CT. Preoperative and postoperative otoendoscopic evaluation (1,3,6 and12 months) was performed with both cold white light endoscopic vision (CWL) and narrowband imaging (NBI). 17 patients were enrolled in the study. Preoperative otoendoscopic examination of WL showed stenosis with a diameter <75% and a tympanic membrane not viewable in all patients. At 12 months of follow-up, 94% of patients had no recurrence of external ear canal stenosis. 88% of patients had normal NBI light vascularization. Our study evaluated how NBI can be a superior method, compared to CWL, to assess the state of the flap and can be relevant in the decision-making process of a re-intervention.

蒂尔施移植物对获得性外耳道闭锁的窄带成像随访:蒂尔施移植物管成形术与窄带成像评估血管化。

获得性外耳道闭锁是外耳道 (EAC) 变窄,看起来被纤维组织或骨组织阻塞。后天性闭锁有两个不同的阶段:湿期和干期。计算机断层扫描 (CT) 扫描可能会显示软组织填充 EAC 的扫描。治疗可以是药物和/或手术。选择的手术治疗以带无皮肤皮瓣的管成形术为代表。据我们所知,没有文章报道过窄带成像随访期间外耳道获得性闭锁血管化和皮瓣血管化分析的数据。本研究评估了 2017 年至 2020 年在我们的萨皮恩扎大学感官器官系接受手术治疗的外耳道获得性闭锁的患者。所有患者都接受了:回忆收集,体格检查,CT。术前和术后耳内镜评估(1、3、6 和 12 个月)采用冷白光内窥镜(CWL)和窄带成像(NBI)进行。17名患者参加了这项研究。WL 的术前耳内镜检查显示直径 <75% 的狭窄,并且在所有患者中都不能看到鼓膜。在 12 个月的随访中,94% 的患者外耳道狭窄没有复发。88% 的患者 NBI 轻度血管化正常。我们的研究评估了 NBI 如何成为一种优于 CWL 的方法,用于评估皮瓣的状态,并与重新干预的决策过程相关。6个月和12个月)用冷白光内窥镜(CWL)和窄带成像(NBI)进行。17名患者参加了这项研究。WL 的术前耳内镜检查显示直径 <75% 的狭窄,并且在所有患者中都不能看到鼓膜。在 12 个月的随访中,94% 的患者外耳道狭窄没有复发。88% 的患者 NBI 轻度血管化正常。我们的研究评估了 NBI 如何成为一种优于 CWL 的方法,用于评估皮瓣的状态,并与重新干预的决策过程相关。6个月和12个月)用冷白光内窥镜(CWL)和窄带成像(NBI)进行。17名患者参加了这项研究。WL 的术前耳内镜检查显示直径 <75% 的狭窄,并且在所有患者中都不能看到鼓膜。在 12 个月的随访中,94% 的患者外耳道狭窄没有复发。88% 的患者 NBI 轻度血管化正常。我们的研究评估了 NBI 如何成为一种优于 CWL 的方法,用于评估皮瓣的状态,并与重新干预的决策过程相关。94%的患者外耳道狭窄未复发。88% 的患者 NBI 轻度血管化正常。我们的研究评估了 NBI 如何成为一种优于 CWL 的方法,用于评估皮瓣的状态,并与重新干预的决策过程相关。94%的患者外耳道狭窄未复发。88% 的患者 NBI 轻度血管化正常。我们的研究评估了 NBI 如何成为一种优于 CWL 的方法,用于评估皮瓣的状态,并与重新干预的决策过程相关。
