Sinu-knit is a dissolvable post-op nasal dressing (intranasal splint) intended to minimize bleeding and edema and to prevent adhesions within the nasal cavity. Made of carboxymethyl cellulose (CMC) that has been formed into a convenient mesh-like fabric, Sinu-knit converts to a dense gel after hydration. This dense gel provides a moist hydrocolloid physical barrier that minimizes occurrence of post-op bleeding and adhesions.
