目的    探讨胸锁乳突肌肌瓣即刻修复腮腺肿瘤术后面部凹陷畸形和减少术后味觉出汗综合征（Frey综合征）发生的临床效果。方法    选择2006年1月至2009年1月蚌埠医学院第一附属医院口腔科腮腺肿瘤住院手术患者68例，分为试验组48例、对照组20例。试验组患者按常规“S”切口施行腮腺肿瘤加腮腺浅叶或全叶切除术，同期行胸锁乳突肌肌瓣转移修复术；对照组则不行同期肌瓣修复，经随访对比观察6月至3年。结果    对照组局部凹陷畸形发生率为90%（18／20），Frey综合征发生率为 55%（11／20）；试验组局部凹陷畸形发生率为16.67%（8／48），Frey综合征发生率为8.33 %（4／48），两组间差异有统计学意义（P < 0. 01）。结论    胸锁乳突肌肌瓣转移修复术是一种即刻修复腮腺肿瘤术后面部凹陷畸形和降低Frey综合征发生率的较好方法。

Clinical study of 48 cases of sternocleidomastoid muscle flap in parotidectomy

Objective To study a new method for immediate repair of facial depression and for reducing Frey＇s syndrome after parotid resection.Methods Choose 68 cases of parotid gland tumors from January 2006 to January 2009 in Oral and Maxillofacial Surgery of the First Hospital affiliated to Bengbu Medical College.The cases were divided into two groups：one group with 20 patients was only treated with parotid tumor resection plus superficial lobectomy or parotidectomy;the other group was done with sternocleidomastoid muscle flap transfer during parotidectomy at the same time.The effect of treatment was observed by follow-up from six months to three years.Results The incidences of facial depression and Frey＇s syndrome were 16.67%（8/48） and 8.33%（4/48） in the experimental group and 90% and 55% in the control group.They were obviously difference in the two groups.Conclusion The method is an ideal operation with functional recovery;the sternocleidomastoid muscle flap transfer can obviously improve post-operative deformity,and prevent the incidence of Frey＇s syndrome.
