Outpatient parotidectomy with or without the use of a post-operative drain: A retrospective bi-institutional study

Abstract

Objective: Parotid surgery is historically performed as an inpatient procedure and suctions drains are predominantly used during surgery. Recent literature provides evidence that outpatient parotid surgery is safe and effective. Our study aims to describe the results of drainless outpatient parotidectomy and outpatient parotidectomy with drain placement and compare their outcomes. Design: Retrospective cohort study. Setting: Bi-institutional retrospective cohort study. Participants: Patients that underwent outpatient drain-less parotidectomy and patients that underwent outpatient parotidectomy with post-operative drain placement. Main Outcome Measures: Complication rates, unplanned post-operative visits, unplanned prolonged stay. Results: Three hundred eighty patients underwent outpatient parotidectomy with drain placement and 31 patients underwent outpatient drainless parotidectomy in two different hospitals. The incidence of haematoma (drain: 3.1% vs. drainless: 0%, p = 1), infection (drain: 14.3% vs. drainless: 13.8%, p = 1) and salivary fistula (drain: 5.6% vs. drainless: 3.4, p = 1) were comparable between both groups. Seroma or sialocele was more frequently seen in the drain-less group (27.6% vs. 6.2%, p
