保留腮腺咬肌筋膜预防Frey''s综合症的试验

目的：研究对比采用保留腮腺咬肌筋膜的翻瓣和切除腮腺咬肌筋膜的翻瓣方法对预防Frey’s综合症的效果。方法：对甲组23例腮腺肿瘤患者在行腮腺切除手术时采用保留腮腺咬肌筋膜；乙组32例腮腺肿瘤患者则采用切除腮腺咬肌筋膜，经过半年至两年半的随访，比较两组患者Frey’综合症的发生率。结果：甲组患者中4例出现进食时出汗现象，发生率为57％。结论：在腮腺切除手术中，保留腮腺咬肌筋膜，可防止了副交感迷走神经未梢的再生，有效地预防了腮腺书后Frey’s综合症的发生。

Preservation of Parotid Masseter Fascia in Preventing Frey''s Syndrome

Objective: To compare the functional outcomes of patients who had parotid masseter fascia reserved and unreserved flap elevating scheme in parotidectomy, especially the morbidity of Frey's syndrome. Methods: Twenty-three patients (group A) had parotid masseter fascia reserved in the parotidectomy, 32 patients (group B) had parotid masseter fascia unreserved in the operation. Compare the morbidity of gustatory sweating syndrome of the two groups. Results: Follow-up after 6 months to 2.5 years, gustatory sweating syndrome occurred in 4 patients of group A (17%), 17 patients in group B (57%). Conclusion: Reservation technic of the parotid masseter fascial in parotidectomy could prevent regeneration of parasympathetic nerve and thus prevent Frey's syndrome post-operation.
