Objective: To determine if following parotidectomy the timing of drain removal, 4 hours versus longer than 1 day post-operatively, affected hematoma and seroma rates in our practice.
Methods: We reviewed all consecutive patients over a 10 year-period who underwent a parotidectomy by the senior author. We then performed single and multivariable analyses of hematoma and seroma rates based on drain removal timing, 4 hours versus longer than 1 day post-operatively, controlling for age, revision surgery, extent of dissection, and anticoagulant use.
Results: 526 patients satisfied the inclusion criteria: 235 (44.7%) with drains removed after 4 hours, and 291 (55.3%) with drain removed on post-operative day 1 or later. There was no statistical difference in post-operative hematoma (2.6% vs 0.7%, p=0.15) and seroma (2.1% vs 1%, p=0.48) rates between the groups.
Conclusion: The timing of drain removal following parotidectomy appears to have no significant impact on hematoma and seroma rates.
- To review the current literature on drain removal timing following parotid surgery
- To develop an understanding of how timing of drain removal might affect the rate of seroma and hematoma formation
