A new type of surgical procedure threads a small balloon through the sinus passages. As the balloon is gently opened, the sinus passages expand, allowing drainage to occur. Some doctors think that this procedure is only appropriate for select patients with sinusitis disease in the maxillary (behind cheek bones), frontal (behind the sides of the forehead), and sphenoid (behind the eyes) sinus regions. It may not work for patients with disease in the ethmoid (between the eyes) sinuses, even though sinusitis commonly occurs in this location. More long-term studies are needed.
Severe complications following FESS are very rare. More common complications include short-term bleeding , inflammation , bruising and an impaired sense of smell . According to various estimates, between 5 and 15 out of 100 people can expect these kinds of temporary side effects following surgery . Your nose is often stuffed up for several days after the procedure and scabs may form, but this gets better quickly. It may take several weeks until the wounds in the sinuses have completely healed, though. That is why it is important to have regular check-ups for several weeks, and to rinse your nose with a saline solution. Your doctor will also remove wound secretions from your nose at several different appointments.
