When is sinus surgery necessary?


Mucus is developed by the body to act as a lubricant. In the sinus cavities, the lubricant is moved across mucous membrane linings toward the opening of each sinus by millions of cilia (a mobile extension of a cell). Inflammation from allergy causes membrane swelling and the sinus opening to narrow, thereby blocking mucus movement. If antibiotics are not effective, sinus surgery can correct the problem.
