This study aimed to analyze the effects of anterior descending mandible (ADM) and free superior mesenteric artery (SMAS) folding flaps on post-parotidectomy facial depression.
This retrospective study examined the effects of sex, age, surgical sample size, method, duration, and blood loss on postoperative complications in 65 patients.
No significant differences involving sex, age, or sample size for surgical resection were observed between the two groups. The incidence of Frey syndrome (P = 0.175) and the locations of facial nerve injuries and tumors were not significantly different between the two groups. However, a statistically significant difference was observed in postoperative facial depression between the groups (P = 0.045, P < 0.05). No significant difference was found between facial nerve injury and Frey's sign in subgroup analysis of facial depression deformities. Within the facial depression group, tumor locations were significantly different (P = 0.021, P < 0.05). In the cases of facial depression after partial parotid resection, no significant difference was observed between ADM implantation and SMAS flap placement. A significant difference was noted between the ADM implantation and SMAS flap groups in the total parotidectomy group (P = 0.046 and P < 0.05, respectively).
Women are more likely to experience facial depression after parotid surgery. Facial depression is most likely to occur after parotid resection if the tumor is located in the deep lobes of the parotid gland. The use of SMAS flaps can prevent facial depression, and both ADM and SMAS flaps can prevent Frey's syndrome. Partial parotid resection reduces the risk of facial nerve injury and facial depression.
本研究旨在分析下颌前降支（ADM）和游离肠系膜上动脉（SMAS）折叠皮瓣对腮腺切除后面部凹陷的影响。
本回顾性研究分析了 65 例患者的性别、年龄、手术样本量、方法、持续时间和失血量对术后并发症的影响。
两组患者在性别、年龄或手术切除样本量方面无显著差异。Frey 综合征（P=0.175）和面神经损伤及肿瘤位置的发生率在两组间无显著差异。然而，两组间术后面部凹陷的发生率存在显著差异（P=0.045，P<0.05）。在面部凹陷畸形的面神经损伤和 Frey 征亚组分析中，未发现显著差异。在腮腺部分切除后面部凹陷组中，肿瘤位置差异有统计学意义（P=0.021，P<0.05）。在腮腺全切除病例中，ADM 植入组与 SMAS 皮瓣组之间无显著差异（P=0.046，P<0.05）。
女性在腮腺手术后更易发生面部凹陷。如果肿瘤位于腮腺深叶，腮腺切除后更易发生面部凹陷。使用 SMAS 皮瓣可预防面部凹陷，ADM 和 SMAS 皮瓣均可预防 Frey 综合征。腮腺部分切除可降低面神经损伤和面部凹陷的风险。
