Background: Off-label drug eluting middle-meatal spacers have shown promising results for improving clinical outcomes following endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). This study evaluates a dexamethasone Sinu-Foam (TM) spacer following ESS for CRS without nasal polyposis (CRSsNP). Methods: Patients with CRSsNP (n = 36) were enrolled into a double-blind, placebo-controlled trial and randomized into either a treatment arm (dexamethasone Sinu-Foam (TM) mixture; n = 18) or placebo arm(Sinu-Foam (TM) alone; n = 18). Therapeutic outcomes were evaluated at 1 week, 4 weeks, and 3 months using sinonasal endoscopy and graded using the Lund-Kennedy scoring system. Postoperative care included nasal saline irrigations and a short course of systemic steroids. Results: All patients completed the study follow-up period. Both study arms experienced significant improvement in endoscopic grading over the study duration (p < 0.001). There was no difference in average endoscopic scores be-tween the treatment and placebo groups at 1 week, 4 weeks, and 3 months (all p > 0.489). Conclusion: This study demonstrated that an off-label drug-eluting middle-meatal spacer of dexamethasone and Sinu-Foam (TM) does not improve endoscopic outcomes in the early postoperative period following ESS when combined with postoperative saline irrigations and a short course of systemic steroids.
