There are two types of sinus surgery: Endoscopic surgery is the type that is done most often. The doctor puts a thin, lighted tool called an endoscope in the nose to remove small amounts of bone or tissue that block the sinus openings. The doctor also can remove polyps.

Like the appendix, sinuses are not a vital organ. One can do just fine without sinuses. People born without sinuses, or who have them surgically replaced, don't appear to have any significant problems.
