Abstract
Objectives/Hypothesis: To assess safety and efficacy of a steroid-releasing implant in improving surgical outcomes when placed in the frontal sinus opening (FSO) following endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). Study Design: Prospective, multicenter, randomized, blinded trial using an intrapatient control design. Methods: Eighty adult (≥ 18 years) CRS patients who underwent successful bilateral frontal sinusotomy were randomized to receive a steroid-releasing implant in one FSO, whereas the contralateral control side received no implant. All patients received standard postoperative care. Endoscopic evaluations recorded at 30-days postendoscopic sinus surgery (ESS) were graded real time by clinical investigators and by an independent, blinded sinus surgeon to assess the need for postoperative interventions in the FSO. Results: Implants were successfully placed in all 80 frontal sinuses, resulting in 100% implant delivery success. At 30-days post-ESS, steroid-releasing implants provided a statistically significant (P = 0.0070) reduction in the need for postoperative interventions compared to surgery alone by an independent reviewer, representing 38% relative reduction. Clinical investigators reported statistically significant reduction in this measure at 30 days (P < 0.0001) and 90 days (P = 0.0129). Clinical investigators also reported a 55.6% reduction in the need for oral steroid interventions (P = 0.0015), 75% reduction in the need for surgical interventions (P = 0.0225), 16.7% reduction in inflammation score, 54.3% reduction in restenosis rate (P = 0.0002), and 32.2% greater diameter of FSO (P < 0.0001) on treated sides compared to control at 30 days. No implant-related adverse events were reported. Conclusion: This study demonstrates the efficacy of steroid-releasing implants in improving outcomes of frontal sinus surgery. Level of Evidence: 1b.
