Sinu-Foam is a dissolvable post-op nasal dressing (intranasal splint) intended to minimize bleeding and edema, and to prevent adhesions within the nasal cavity. Starting as a dry carboxyethyl cellulose (CMC) fiber within a syringe, the CMC forms a viscous foam when properly mixed with sterile water. This foam conforms to nasal and sinus cavities during placement and provides a moist, hydrocolloid physical barrier that will naturally dissolve over several days.
