Background: Preoperative corticosteroids have been shown to improve surgical visibility and intraoperative blood loss for chronic rhinosinusitis with nasal polyposis (CRSwNP) patients undergoing endoscopic sinus surgery (ESS). However, there is no consensus on the optimal dosing regimen. Methods: A randomized, controlled trial was conducted to compare low, medium, and high dose corticosteroids prior to ESS. Patients with CRSwNP refractory to medical management were randomized to low (N = 8), medium (N = 10), or high (N = 5) dosing regimens of corticosteroids prior to ESS. Baseline disease severity was measured with the 22-item Sino-nasal Outcome Test and Lund-Mackay scores. Modified Lund-Kennedy endoscopic scores (MLKES) were measured at baseline and after corticosteroid treatment. Intraoperative parameters were measured including Boezaart surgical visibility score, intraoperative blood loss, and operative time. Results: Medium dose corticosteroids demonstrated a superior surgical visibility score to low dose and comparable results to high dose, but these results were not significant (p = 0.33). No significant difference was observed between groups for total blood loss (p = 0.15), operative time (p = 0.87), or change in MLKES (p = 0.27). Conclusions: Current recommendations include the use of preoperative corticosteroids in patients with CRSwNP undergoing ESS, but there is no consensus on dose or duration. We did not find a statistically significant difference in surgical field visibility, intraoperative blood loss, or operative time between different dosing regimens. Further studies are needed to evaluate the efficacy of a low-dose preoperative regimen with the goal of reducing cumulative patient exposure to systemic corticosteroids.
