目的:探讨脱细胞真皮基质植入对Frey综合征的预防作用。方法:89例腮腺良性肿瘤手术病例分为实验组和对照组,实验组42例腮腺切除术后植入脱细胞真皮基质,对照组腮腺切除术后不植入脱细胞真皮基质,分别于术后12个月及24个月时复查对比两组患者Frey综合征发生率。结果:实验组术后12个月及24个月复查,Frey综合症发生率均低于对照组,发生率差异有统计学意义;两组患者Frey综合症发生率与腮腺肿块大小无明显相关。结论:近期观察显示,异种脱细胞真皮基质植入是一种简便有效的降低Frey综合症发生率的方法。
Objective: To investigate the preventive effect of acellular dermal matrix implantation on Frey syndrome. Methods: A total of 89 cases of parotid benign tumor were divided into experimental group and control group. In the experimental group, 42 cases of acellular dermal matrix were implanted after parotidectomy. In the control group, acellular dermal matrix was not implanted after parotidectomy. At 12 months and 24 months, the incidence of Frey’s syndrome was compared between the two groups. Results: The incidence of Frey syndrome in experimental group was lower than that in control group at 12 months and 24 months postoperatively. The incidence of Frey syndrome was not significantly correlated with the size of parotid gland in both groups. Conclusion: Recent observations show that xenografted acellular dermal matrix implantation is a simple and effective method to reduce the incidence of Frey syndrome.
