How does Sinuva nasal implant work?

Official answer


The Sinuvia Sinus Implant is used for treatment of nasal polyps in patients ≥ 18 years of age who have had ethmoid sinus surgery. A trained physician places the implant under endoscopic visualization in the ethmoid sinuses near the bridge of your nose. The implant releases mometasone furoate, a corticosteroid that helps to lessen swelling and inflammation in the nasal passages. The implant, from Intersect ENT, Inc., can be left in place to gradually release the corticosteroid over a 90 day period.

What are Nasal Polyps?

Nasal polyps are benign (noncancerous) growths on the lining of the inside of the nose or sinuses. These polyps usually occur in both the right and left nasal passages, are swollen, and can obstruct air flow. People with asthma, infections, or allergies may be more prone to nasal polyps. Symptoms of nasal polyps do not always occur, but if they grow too large they can lead to problems with breathing, sense of smell, or infections.
