Abstract

OBJECTIVES: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after superficial parotidectomy for benign parotid disorders. METHODS: From 2013-2015, all patients who underwent total superficial parotidectomy for benign parotid disorders were randomly allocated to be drained or not, post-operatively. Operative and postoperative outcomes including complications (seroma, hematoma), necessity for aspiration of seroma, re-suturing and hospital stay were all assessed. The sample size was ascertained to be 50 in each arm and the allocation was on the basis of computer generated opaque envelopes. RESULTS: 25 patients were in the drain arm while 17 had no drain placed. The Incidence of seroma was analyzed on the basis of ITT and per protocol analysis. We found a statistically significant increased incidence of seroma formation, needing repeated aspiration in the patients with no drains. We analyzed various other factors such as operating time, the HPE report, and size of specimen and found no statistical correlation with the formation of seroma. CONCLUSION: These findings suggest that postoperative complications are increased when postoperative drainage is not done following superficial parotidectomy. In the light of these findings, the routine use of drains is recommended following parotid surgeries.
