To develop a new approach of endoscopic resection for benign parotid tumor through a cosmetic retroauricular incision with a water sac establishing the operative space.
Fifty-eight patients with benign parotid superficial lobe tumor were randomly assigned to an endoscopic (29 patients) or a conventional (29 patients) surgery group. The maximum diameter of the tumors was 6 cm. The subjective satisfaction scores with the incision scar, incision length, operative bleeding volume, postoperative complications, and recurrence rate were compared between the groups.
All operations were successfully performed. The endoscopic incision length (4.3±0.5 cm), bleeding volume (26.6±10.4 mL), and incidence of temporary facial paresis (6.9%) differed from the conventional surgery group (P<.05). The scars were almost invisible behind the ear. The mean patient satisfaction score was 8.9±0.7 in the endoscopic surgery group and 6.7±1.8 in the conventional surgery group (P<.05). Otherwise, Frey's syndrome and salivary fistula incidences were 3.4% (1/29) and 3.4% (1/29), respectively, in the endoscopic surgery group, which was not significantly different from the conventional surgery group (P>.05). No tumor recurrence was found during the 3-72 months of follow-up.
Endoscopic resection through a cosmetic retroauricular incision with a water sac establishing operative space is a feasible method for treatment of benign parotid superficial lobe tumor. Its main advantages are that the small and concealed operative scars improved the cosmetic results, and it provided a novel method for establishing the operation working space that could reduce the operative trauma.
通过耳后美容切口并利用水囊建立手术空间，开发一种新的内镜下切除腮腺良性肿瘤的方法。
58例腮腺浅叶良性肿瘤患者被随机分为内镜手术组（29例）和传统手术组（29例）。肿瘤最大直径为6cm。比较两组患者对切口瘢痕、切口长度、术中出血量、术后并发症及复发率的主观满意度评分。
所有手术均成功完成。内镜手术组的切口长度（4.3±0.5cm）、出血量（26.6±10.4mL）及暂时性面瘫发生率（6.9%）与传统手术组不同（P<0.05）。耳后瘢痕几乎不可见。内镜手术组患者平均满意度评分为8.9±0.7，传统手术组为6.7±1.8（P<0.05）。此外，内镜手术组的味觉出汗综合征和涎瘘发生率分别为3.4%（1/29）和3.4%（1/29），与传统手术组无显著差异（P>0.05）。随访3至72个月期间未发现肿瘤复发。
通过耳后美容切口并利用水囊建立手术空间的内镜切除术是治疗腮腺浅叶良性肿瘤的一种可行方法。其主要优点是手术瘢痕小且隐蔽，改善了美容效果，并提供了一种建立手术操作空间的新方法，可减少手术创伤。
