A retrospective study was done on 64 patients who underwent superficial or subtotal parotidectomy for a primary benign tumor of the parotid gland. Factors, such as age, sex, smoking, alcohol consumption, type of surgery, duration of surgery, pathology of lesion, and size of lesion, were reviewed in a multivariate statistical analysis to determine if any factor alone or in combination contributed to the development of functional facial nerve weakness postoperatively. Only the age of the patient was found to have a statistically significant causal relation using the Pearson chi-square method (p = 0.015). The marginal mandibular branch was affected in nine of 10 cases. Different surgical approaches cited in the literature are discussed, along with the possible role of ischemic injury to the facial nerve during parotidectomy.
对64例因腮腺原发性良性肿瘤接受浅叶或次全腮腺切除术的患者进行了一项回顾性研究。在多变量统计分析中，对年龄、性别、吸烟、饮酒、手术类型、手术时长、病变病理及病变大小等因素进行了评估，以确定是否有任何单一因素或多种因素共同导致术后功能性面神经麻痹的发生。采用Pearson卡方检验法发现，仅患者年龄具有统计学上的显著因果关系（p = 0.015）。10例中有9例下颌缘支受到影响。文中讨论了文献中提到的不同手术方法，以及腮腺切除术中面神经缺血性损伤的可能作用。
