The Right Nasal Packing for Your Patient

NovaShield Nasal Packing for FESS

Chitosan-Based Nasal Packing

NovaShield nasal packing is made from chitosan, a polymer chemical produced from chitin, a component of the hard external shell of shellfish (e.g., crab, lobster, and shrimp). Chitosan's hemostatic properties have been extensively studied.1-10

Hyaluronic Acid-Based Nasal Packing

MeroGel® and MeroPack® nasal packing use esterified hyaluronic acid (HYAFF®), a naturally occurring constituent of the extracellular matrix that helps keep wounds moist, reduce adhesions, and decrease healing time.11
