mometasone-furoate and Ethmoid-Sinusitis

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.. Prospective, multicenter, randomized, controlled, double-blind trial using an intrapatient control design.. Otolaryngology-head and neck surgery centers; both academic and private practices.. 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.. 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.. 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.

Disease recurrence and adverse wound healing in the form of inflammation, polyposis, adhesions, and middle turbinate lateralization may induce suboptimal outcomes following sinus surgery. The study objective was to assess the safety and effectiveness of a bioabsorbable, steroid-eluting implant used following functional endoscopic sinus surgery in patients with chronic rhinosinusitis (CRS).. Prospective, multicenter, single-cohort trial enrolling 50 patients.. The study allowed bilateral or unilateral steroid-eluting implant placement. Oral and topical steroids were withheld for 60 days postoperatively. Endoscopic follow-up was performed to 60 days. Patient-reported outcomes (Sino-Nasal Outcome Test-22 Questionnaire, Rhinosinusitis Disability Index) were collected to 6 months. Efficacy was assessed by grading inflammation, polyp formation, adhesions, and middle turbinate position. Safety assessment included ocular exams at baseline and 30 days.. Implants were successfully placed in all 90 sinuses. Mean inflammation scores were minimal at all time points. At 1 month, the prevalence of polypoid edema was 10.0%, significant adhesions 1.1%, and middle turbinate lateralization 4.4%. Changes from baseline in patient-reported outcomes were statistically significant (P < .0001). No clinically significant changes from baseline in intraocular pressure occurred.. This consecutive case series provides clinical evidence of the safety, effectiveness, and clinical utility of a bioabsorbable steroid-eluting implant for use in CRS patients. The implant was associated with favorable rates of sinus patency. At 1 month, minimal degrees of inflammation and adhesions were observed, suggesting a positive clinical impact of local steroid delivery without evidence of ocular risk.
