Endoscopic sinus surgery can be used to treat a variety of sinus blockage problems. This procedure is used to treat sinusitis; remove polyps that are blocking the sinus cavity; enlarge holes that sinuses drain through; remove the walls between the sinuses to make them bigger; create new openings to make it easier for mucus to drain; and straighten a deviated septum, which can obstruct the sinuses.

What to expect

Endoscopic sinus surgery is usually done under general anesthesia, and you can expect to go home the same day.

The doctor will insert an endoscope—a thin, hollow, lighted tube that allows him or her to see the sinuses on a video screen—through a tiny incision. Then, the doctor will insert small surgical instruments through one or more tiny incisions made inside the nose. It does not involve cutting through the skin. The doctor can then remove the blockage.

How to Prepare

The doctor will advise you about any medications that need to be discontinued before the procedure. You will not be allowed to eat or drink anything after midnight the evening before the procedure.

The most preparation needed is for after the procedure. You will have to arrange for a ride home. Once home, you must rest to prevent serious bleeding, although some bleeding and drainage after the surgery is normal. A humidifier is encouraged to keep the nose moist. The doctor will advise you about any follow-up visits and when you can return to work.
