Pain SeverityPrimary· Average pain score will be collected for preoperative visit (the day before surgery)
A 10-cm visual analog scale (VAS) will be used to assess pain severity.The VAS is a continuous, patient-reported outcome measure determined using a horizontal 100-mm scale ranging from "no pain" with a score of 0 to "worst imaginable pain," corresponding to a score of 100.

Medication LogPrimary· Postoperative day 1 to 7
Patients kept a daily medication log and reported the number of doses consumed per day (650mg acetaminophen, 600mg ibuprofen, 5mg oxycodone). The mean number of medication doses per day was calculated for each treatment group.

Brief Pain Inventory (BPI) ScoreSecondary· BPI score will be collected at the preoperative visit
The Brief Pain Inventory (BPI) Severity short form is a validated, patient-reported outcome measure that assesses pain over a 24-hour period. The Pain Severity score is calculated as a composite mean score using the degree of pain a patient experiences per day at its "least," "worst," "average," and "now." The score ranges from 0 to 10 (higher indicates more pain).

Sponsor's own description
Given the ongoing national opioid epidemic, an increased interest has developed in optimizing opioid prescribing practices of physicians, including otolaryngologists. Endoscopic sinus surgery (ESS) is one of the most commonly performed surgeries by otolaryngologists with over 250,000 ESS's performed annually in the U.S. Multiple studies have shown that, compared to the amount patients actually consume, otolaryngologists prescribe a high quantity of opioids to patients recovering from ESS). It has been shown that these excess opioid medications contribute to prolonged use or abuse by the patient, family members, or friends. The purpose of this study is to better understand the pain management requirements of patients who undergo ESS for recurrent acute rhinosinusitis (RARS) or chronic rhinosinusitis (CRS).
This prospective, randomized, multi-institutional controlled trial will aim to determine the degree to which pain following ESS can be adequately controlled by non-opioid medications. It will also determine whether post-ESS narcotic use can be avoided entirely, or at least significantly limited. Patients will be randomized into two groups, each of which will receive a stepwise analgesic regimen consisting of acetaminophen and oxycodone or acetaminophen and ibuprofen. Pain will be assessed daily using visual analog scales (VAS) and the Brief Pain Inventory (BPI).
The results of this study will help to develop a standardized approach to pain management in the post-ESS setting and help to elucidate the role of non-opioid pain medications. The ultimate goal would be to positively affect opioid prescribing patterns among surgeons who perform ESS in order to significantly reduce the quantity of opioids prescribed to patients while continuing to adequately manage patients' pain.
