Background: Postparotidectomy sialocele is a frustrating challenge. Published rates of postparotidectomy fluid collections range from 6% to 39%. We report our experience of 398 parotidectomies performed over a 6-year period. Methods: A retrospective chart review of parotidectomies performed over a 6-year period was completed. Drain placement, smoking status, tumor size, and postoperative utilization of scopolamine were analyzed. Binary logistical regression and odds ratio calculations were performed. Results: Postparotidectomy sialocele occurred in 25% of patients. Neither suction drain placement nor usage of immediate postoperative scopolamine (in a 22-patient subset) prevented sialocele formation. Smoking status also did not correlate. Increasing resection size was linearly correlated with the risk of sialocele. Conclusion: Drain placement and smoking status do not correlate with sialocele prevention after parotidectomy. Sialocele formation directly correlates with the resection size. These data may guide preoperative counseling; however, additional work is necessary to identify effective prevention mechanisms for postparotidectomy sialocele.
