Multicenter study on the effect of nonsteroidal anti-inflammatory drugs on postoperative pain after endoscopic sinus and nasal surgery.

Background: The taboo of avoiding nonsteroidal anti-inflammatory drugs (NSAIDs) after functional endoscopic sinus surgery (FESS) has been waning. The impetus to reduce opioid prescriptions in view of the opioid epidemic led the authors to change their practices to include NSAIDs after sinus surgery. This study's aim was to analyze the differences between patients before and after we began recommending NSAIDs after FESS.
