The objective of this study was to analyze the diagnosis and postoperative complications of benign parotid tumors for a series of 300 patients who underwent the same diagnostic methods and operation procedure in a single institute.
MATERIALS & METHODS: A series of 300 patients who underwent primary parotidectomy for benign parotid tumors over a 12-year period was reviewed.
There were 145 female and 155 male paitents. The site of the tumors was divided into three groups, superficial, deep, and lower pole tumor. The number of each type of the tumor was 152, 45, 103 cases, respectively. The most common pathology of the parotid tumor was a pleomorphic adenoma (147 cases) followed by a Warthin tumor (111 cases). Pleomorphic adenomas and Warthin tumors accounted for 86% of all benign tumors. The accuracy rate of fine needle aspiration cytology (FNAC) for all benign tumors was 66%, 80% for pleomorphic adenoma and 67% for Warthin tumor. Transient facial nerve dysfunction was observed in 63 patients (20.3%) in all benign parotid tumors, and no patients developed a permanent weakness. The incidence of transient facial nerve dysfunction was 16.4% in superficial tumors, 55.3% in deep tumors, and 10.7% in lower pole tumors. Significant risk factors for development of a transient facial palsy were the site of tumors, operation time, and bleeding volume. Transient facial nerve dysfunction recovered with 1.7 months and 2.8 months in superficial and deep tumors, respectively.
The accuracy rate of FNAC for benign parotid benign tumors was 66%. The incidence of transient facial nerve dysfunction in deep tumors was significantly higher compared to that in superficial and lower pole tumors. According to the rate of facial palsy, operation time, and bleeding volume, benign parotid tumor should be divided into three groups, superficial, deep, and lower pole tumors.
本研究的目的是分析在单一机构接受相同诊断方法和手术程序的300例腮腺良性肿瘤患者的诊断情况及术后并发症。
回顾了在12年期间接受腮腺良性肿瘤初次腮腺切除术的300例患者。
有145例女性患者和155例男性患者。肿瘤部位分为三组，即浅叶、深叶和下极肿瘤。每种类型的肿瘤数量分别为152例、45例、103例。腮腺肿瘤最常见的病理类型是多形性腺瘤（147例），其次是沃辛瘤（111例）。多形性腺瘤和沃辛瘤占所有良性肿瘤的86%。所有良性肿瘤的细针穿刺细胞学检查（FNAC）准确率为66%，多形性腺瘤为80%，沃辛瘤为67%。在所有腮腺良性肿瘤患者中，63例（20.3%）出现短暂性面神经功能障碍，无患者出现永久性面瘫。浅叶肿瘤短暂性面神经功能障碍的发生率为16.4%，深叶肿瘤为55.3%，下极肿瘤为10.7%。发生短暂性面瘫的显著危险因素是肿瘤部位、手术时间和出血量。浅叶和深叶肿瘤的短暂性面神经功能障碍分别在1.7个月和2.8个月恢复。
腮腺良性肿瘤的FNAC准确率为66%。深叶肿瘤短暂性面神经功能障碍的发生率明显高于浅叶和下极肿瘤。根据面瘫发生率、手术时间和出血量，腮腺良性肿瘤应分为三组，即浅叶、深叶和下极肿瘤。
