Indications for Absorbable Steroid-Eluting Sinus Implants: Viewpoint via the Delphi Method

Absorbable steroid-eluting sinus implants provide targeted corticosteroid release over a sustained period and are designed to prevent both undesirable adhesion formation and sinus ostia restenosis. Here, we highlight the key evidence of these implants to date and query a group of experts via a Delphi process on the indications and optimal timing for intraoperative or in-office placement of these implants. Six of a total of 12 statements reached consensus and were accepted. Overall, experts largely agree that intraoperative or in-office use of steroid-eluting stents could be considered for patients: (1) who are diabetic or intolerant of oral steroids, (2) undergoing extended frontal sinus surgery, and (3) with recurrent stenosis. Given the lack of expert consensus on other key statements, clinicians should carefully consider these treatment options on a case-by-case basis after shared decision-making.

Mometasone furoate sinus implant - a new targeted approach to treating recurrent nasal polyp disease

Introduction: Chronic rhinosinusitis (CRS) is a broad heterogeneous inflammatory disorder of the nose and paranasal sinuses, resulting from the dysfunctional interplay between host immunity, defective epithelial barrier, and environmental factors. CRS with nasal polyps (CRSwNP) is considered a more severe clinical phenotype with greater burden of symptoms and higher relapse rate, especially with comorbid asthma or aspirin sensitivity. Available treatment options after endoscopic sinus surgery (ESS) - systemic corticosteroids or revision surgery - have significant risks and limitations. Areas covered: Bioabsorbable, steroid-eluting implants have been studied extensively for the ability to dilate and re-establish sinus patency by the localized, controlled delivery of topical corticosteroids to diseased sinonasal lining and nasal polyps. This review provides a comprehensive, up to date analysis of the literature regarding a novel, office-based, mometasone furoate (MF) sinus implant that may treat patients with recurrent CRSwNP after ESS. Expert commentary: Clinical evidence has demonstrated the safety and efficacy of steroid-eluting implant in the reduction of polyp size, symptom burden, and the need for revision sinus surgery. MF sinus implants may play an important role in the management of patients with recurrent polyposis after sinus surgery.
