【摘要】 目的 分析肋腺切除手术后面神经下颌缘支，颊支和颧支的损伤与病理诊断及手术方式的关系。方法 对１０１例经病理诊断为腮腺肿瘤的病例术后面神经功能情况进行临床追踪观察，并对其结果进行分析。结果 腮腺恶性肿瘤术后面神经下颌缘支，颊支和颧支损伤发生机率分别是良性肿瘤的２．５，２．４，５．４倍；腮腺全切术后面神经重要分支损伤发生率明显高于浅叶摘除术和节段切除术；下颌缘支损伤的机率较其他分支高。结论面神经主要分支损伤与手术方式、肿瘤性质密切相关，选择适当的手术方式可减少其发生机率。更多还原

【Abstract】 Objective The article intends to the incidence of main branches of facial nerve dysfunction following parotidectomy and to correlate this with the extent of parotid gland resection and the pathological diagnosis. Methods Between 1996 and 2000, clinical tracing observation of 101 patients who underwent parotid surgery was studied to analyze the relation between dysfunction of main branches of facial nerve and the extent of parotidectomy and the pathological diagnosis. Results The incidence of dysfunction of the marginal mandibular branch, buccal branch and zygomatic branch following parotidectomy in malignant neoplasia was respectively 2.5. 2.4. 5.4 times the incidence of benign neoplasia. The dysfunetion rate of the three branches in total partidectomy was higher than that of superfical and local parotidectomy. The marginal mandibular branch was more traumatic than other branches. Conclusion The dysfunction of facial nerve branches is correlated with the pathodiagnosis and especially the surgical management.更多还原
