腮腺良性肿瘤手术中面神经颈支的解剖

目的探讨应用面神经颈支为向导显露面神经并完成腮腺良性肿瘤切除的可行性和安全性。方法收治腮腺良性肿瘤87例，分别应用以面神经总干、颊支、下颔缘支和颈支为向导的方法显露出面神经，完成腮腺肿瘤切除，并观察术后面神经的功能情况。结果应用面神经总干、颊支、下颔缘支和颈支显露面神经的病例分别为10、8、28、41例，术后出现的面神经损伤率依次为30％、37．5％、46，4％、24．3％，其中应用下颔缘支和颈支的方法术后面神经损伤几率的比较，P〈0.05，有显著差异性。结论应用面神经颈支为向导显露面神经总干及其他分支的方法，方便可行，优于通过下颔缘支的方法。

Ramus colli nervi facialis dissect in the surgical management of benign parotid tumor

OBJECTIVE To study the feasibility and security of parotidectomy for parotid benign tumor by tracing cervical branch to expose facial nerve. METHODS Parotid benign tumor of 87 patients were studied. We exposed facial nerve by tracing main facial nerve branch, buccal branch, marginal mandibular branch and cervical branch in parotidectomy for parotid benign tumor and observed the function of facial nerve after operation. RESULTS The number of patients traced by main facial nerve branch, buccal branch. marginal mandibular branch and cervical branch group were 10、8、 28 and 41 respctively, and the percentage of facial nerve injury after operation were 30%. 37.5%. 46.4% and 24.3%. The percentage of facial nerve injury was statistically different between the marginal mandibular branch group and the cervical branch group （P〈 0.05） , CONCLUSION Exposing facial nerve and it＇s branchs by tracing cervical branch is a feasible method and tracing marginal mandibular branch indicates better results than tracing other branches.
