目的探讨腮腺混合瘤术后面神经功能损伤与腮腺切除手术方式的关系。方法对82例术后病理诊断为腮腺混合瘤的病例术后面神经功能情况进行回顾性分析,按H-B系统面神经功能分级方法以(HB>1)视为术后面神经功能损伤进行评价。结果82例治疗手术中,面神经损伤32例,占38.78%。其中腮腺区域性切除32例,术后出现面神经功能障碍5例(15.7%),腮腺浅叶摘除30例中,术后出现面神经损伤11例(37%),腮腺全切解剖面神经的20例,术后全部出现暂时性面瘫(100%),所有面神经功能障碍均在3个月内恢复。结论腮腺全切术后面神经重要分支功能损伤发生率明显高于腮腺浅叶摘除术和腮腺区域切除术,面神经主要分支功能损伤与手术方式密切相关。
Objective To investigate the relationship between facial nerve function after parotid mixed tumor and parotid surgery. Methods The facial nerve function of 82 patients with pathological diagnosis of parotid gland tumor was retrospectively analyzed. Facial nerve function grading was performed according to H-B system (HB> 1). Results 82 cases of surgical treatment, facial nerve injury in 32 cases, accounting for 38.78%. There were 32 cases of parotid regional excision, facial nerve dysfunction in 5 cases (15.7%), 30 cases of parotid ablation, facial nerve injury in 11 cases (37%), parotid gland dissection in 20 cases, All postoperative facial paralysis (100%), all facial nerve dysfunction were recovered within 3 months. Conclusions The incidence of major facial nerve injury after total parotid gland resection is significantly higher than that of parotid excision and parotid gland excision. The major functional impairment of facial nerve is closely related to the surgical approach.
