OBJECTIVE: Endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) may be compromised by postoperative inflammation, polyposis, and adhesions, often requiring subsequent intervention. To address this issue, the authors investigated the safety and effectiveness of controlled delivery of mometasone furoate to the sinus mucosa via bioabsorbable implants deployed at the time of ESS.

STUDY DESIGN: Prospective, multicenter, randomized, controlled, double-blind trial using an intrapatient control design.

SETTING: Otolaryngology-head and neck surgery centers; both academic and private practices.

SUBJECTS AND METHODS: The study enrolled 105 patients with CRS undergoing bilateral ethmoidectomy to compare the effect of drug-releasing to non-drug-releasing implants using an intrapatient control design. Postoperative interventions, polyposis, and adhesions were assessed postoperatively. Efficacy was determined through independent analysis of randomized video-endoscopies by 3 blinded sinus surgeons. Safety assessments included ocular examinations.

RESULTS: Implants were successfully deployed in all 210 ethmoid sinuses. Compared with control sinuses with non-drug-releasing implants, the drug-releasing implant provided a 29.0% relative reduction in postoperative interventions (P = .028) and a 52% (P = .005) decrease in lysis of adhesions. The relative reduction in frank polyposis was 44.9% (P = .002). Similar reductions were observed in real-time grading performed by the clinical investigators. No clinically significant changes from baseline in intraocular pressure or cataracts were observed.

CONCLUSION: This study provides a high level of evidence that use of steroid-releasing implants that apply a sustained release of corticosteroid improves surgical outcomes by reducing synechiae formation, polyposis, and the need for postoperative interventions, with no observable ocular safety risk.
