Objective:To analysis the data of the patients with parotid tumors, clarify the contributing factors of Frey syndrome, and to evaluate the role of soft tissues membrane SIS in prevention of Frey syndrome after parotidectomy. Method:The data of 95 patients who suffered from parotid tumors and underwent parotidectomy were included in this study. The relationship between the patients' age, sex, tumor location ,tumor size, disease pathology, type of resection, SIS application and the incidence of Frey syndrome were statistically analyzed . Result:The incidence of Frey syndrome after parotidectomy for 95 patients was 25.3%. Age, sex, tumor location and size, disease pathology, type of resection did not appear to be associated with development of Frey syndrome（P>0.05）. SIS application was the only statistically significant factor（P<0.01）, and SIS could prevent Frey syndrome after parotidectomy. Conclusion:Frey syndrome is one of the common complicationsafter parotidectomy. Implantation of SIS is an effective method for prevention of Frey syndrome after parotidectomy.
目的：分析腮腺肿瘤术后发生Frey综合征的影响因素，明确软组织修补片SIS用于预防腮腺肿瘤切除术后Frey综合征的疗效。 方法：对95例腮腺肿瘤患者资料进行回顾性分析，明确患者年龄、性别、肿瘤位置与大小、病理类型、手术方式、术中SIS使用与术后Frey综合征发生的相关性。 结果：95例腮腺肿瘤切除术后患者Frey综合征的发生率为25.3%。术后Frey综合征的发生与患者年龄、性别、肿瘤位置与大小、病理类型、手术方式等均无显著相关性（P>0.05）；术中SIS的使用可减少术后Frey综合征的发生（P<0.01）。 结论：Frey综合征是腮腺肿瘤切除术后常见并发症，术中软组织修补片SIS的应用可有效降低腮腺肿瘤术后Frey综合征的发生率。.
