Objective: To observe the efficacy of prosthodontics membrane (acellular dermal matrix) implant to prevent Frey syndrome after parotidectomy. Methods: 75 patients underwent parotidectomy in our hospital, 3Scases implant prosthodontics membrane (acellular dermal matrix) within the flap and parotid bed ,and others without implantation. Results: 29 cases (72.5%) present subjective symptoms of Frey syndrome in non-implantation group,and only 1 case (2.9%) with subjective symptoms in prosthodontics membrane (acellular dermal matrix) implantation group. Conclusion: Prosthodontics membrane (acellular dermal matrix) implantation is effective for prevention Frey syndrome after parotidectomy.%目的:观察口腔修复膜(异种脱细胞真皮基质)植入对腮腺术后Frey综合征的预防作用.方法:我科近五年来施行的腮腺手术病人共75例,其中35例选择在皮瓣与腮腺床之间植入口腔修复膜,术后随访1-2年,以患者主观症状判断是否存在Frey综合征.结果:在未使用口腔修复膜的患者中,有29例(72.5％)出现Frey综合征的症状,在使用修复膜的患者中只有1例(2.9％)出现症状.两组之间有显著性差异(P＜0.01).结论:口腔修复膜(异种脱细胞真皮基质)能有效预防腮腺手术后Frey综合征的发生.
