목적: Parotid sialoceles are a relatively common complication after partial parotidectomy. However, there is little information in the literature relating to risk factor for sialocele. The purpose of this study was to identify the prevalence of sialoceles and the risk factors associated with their formation following parotidectomy. 방법:We performed a retrospective analysis of the data from consecutive patients who underwent partial superficial parotidectomy of parotid tumors. Variables collected in the dataset included age, sex, body mass index (BMI), underlying diseases, and preoperative imaging results. Operative variables including tumor type, incision type, tumor size, and method of parenchymal disruption were also assessed. 결과:Twenty-three out of 357 patients (6.4%) undergoing partial superficial parotidectomy developed sialoceles during the postoperative period. Sialoceles occurred more often in patients who had tumors in the anterior portion of the parotid gland. Multivariate analysis showed that an anterior tumor location was a significant risk factor for sialocele formation (odds ratio = 3.84, P = 0.022). There was no statistically significant difference between those who developed sialoceles and those who did not with respect to age, sex, BMI, incision type, tumor size, or method of disruption. 결론:The incidence of sialocele development was 6.4% in patients undergoing partial superficial parotidectomy. An anterior tumor location may increase the risk of sialocele formation.
