BACKGROUND:Inflammation/polyp recurrence, adhesions, and middle turbinate lateralization are causes of suboptimal outcomes following sinus surgery and lead to increased rates of revision. A bioabsorbable, drug-eluting stent was evaluated for its ability to preserve sinus patency by providing controlled steroid delivery to the sinus mucosa. The study objective was to assess safety and efficacy of a steroid-eluting sinus stent when used following functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis (CRS). METHODS: Prospective, multicenter, randomized, double-blind clinical trial, enrolling 43 patients in 2 groups. One group (n = 38) used an intrapatient control design comparing drug-eluting to non-drug-eluting stents. The other group (n = 5) received bilateral drug-eluting stents to assess systemic safety. Endoscopic follow-up was performed for 60 days. Efficacy endpoints included assessment of inflammation, polyp formation, adhesions, and middle turbinate position. RESULTS: Stents were successfully deployed in all 86 sinuses. Compared to the control stent, the drug-eluting stent provided statistically significant reduction in inflammation at days 21 to 45 (p < 0.003), frequency of polyp formation (p = 0.0391), and frequency of significant adhesion (p = 0.0313). Reduced frequency of middle turbinate lateralization was also apparent though not statistically significant. No device-related adverse events occurred. Eluted steroid was unquantifiable systemically and there was no evidence of adrenal cortical suppression. CONCLUSION: This study demonstrates the safety and efficacy of a novel bioabsorbable, steroid-eluting stent for use in CRS patients. The steroid-eluting stent is effective in improving wound healing by preserving sinus patency, reducing inflammation, and minimizing adhesions via controlled local steroid delivery without measurable systemic exposure.
