Evaluation of the Safety and Performance of a Bioresorbable Nasal Dressing Containing Mometasone Furoate (MF)

Enrolling by invitation · Not applicable

Conditions studied: Chronic Rhinosinusitis (CRS), Chronic Rhinosinusitis (CRS) With and Without Nasal Polyps

In brief

The primary objective of the study is to evaluate the safety and effectiveness of OCEAN as an adjunct aid in wound healing after nasal/sinus surgery and to demonstrate that OCEAN is non-inferior compared to a steroid-eluting sinus stent.
