相比传统的开放手术方法，关于内窥镜辅助下进行的局部浅表腺体切除术（PSP）的长期肿瘤复发率和并发症的报道极为罕见。本回顾性研究包括306名患有浅表腺体良性肿瘤的患者，被分为内窥镜组（内窥镜辅助下的PSP，n = 102）和对照组（常规PSP，n =204）。两组在临床和病理特征上没有显著差异，只有在年龄方面存在差异（P = 0.001）。在平均随访时间为125.1个月期间，3名患者被确认出现了复发。内窥镜组中有10名患者（9.8%）和对照组中有22名患者（10.8%）出现了一过性面神经麻痹（P = 0.792），并在手术后6个月恢复正常。分别有9名患者（8.8%）和19名患者（9.3%）患有Frey综合征（P = 0.889）。耳廓感觉缺失分别发生在24名患者（23.5%）和57名患者（27.9%）身上（P = 0.410）。内窥镜组的患者对术后瘢痕比对照组的患者更满意（P < 0.001）。本研究表明，内窥镜辅助下的PSP具有治疗效果，且整体美容效果优于常规方法，并且不增加术后并发症或局部复发率的发生率。版权所有 © 2023。Elsevier Inc.发表。

Long-term tumour recurrence rates and complications of endoscope-assisted partial superficial parotidectomy (PSP) are rarely reported compared to traditional open approaches. This retrospective study included 306 patients with superficial parotid benign neoplasms who were divided into an endoscopy group (endoscope-assisted PSP, n = 102) and a control group (conventional PSP, n = 204). There were no significant differences in clinical and pathological characteristics between the two groups, except age (P = 0.001). Three patients had confirmed recurrence during a mean follow-up duration of 125.1 months. Ten (9.8%) patients in the endoscopy group and 22 (10.8%) in the control group developed transient facial nerve palsy (P = 0.792), and recovered 6 months after the operation. Nine (8.8%) and 19 (9.3%) patients, respectively, suffered from Frey syndrome (P = 0.889). A sensory deficit of the auricle occurred in 24 (23.5%) and 57 (27.9%) patients respectively (P = 0.410). Patients in the endoscopy group were more satisfied with the postoperative scar than those in the control group (P < 0.001). This study demonstrated that the endoscope-assisted PSP can be curative, with better cosmetic outcomes than the conventional approach, and does not increase the incidence of postoperative complications or the local recurrence rate.Copyright © 2023.
