Nasal polyps can be difficult to get rid of permanently, but steroid medication can often help shrink them, and surgery to remove them can be carried out if medication doesn't help. The main treatments are: 1  corticosteroid nose drops or nasal sprays to shrink the polyps over a number of weeks or months.
Surgery to remove nasal polyps may be recommended if steroid medication doesn't help or your polyps are particularly large. The procedure to remove nasal polyps is called endoscopic sinus surgery. It's carried out under general anaesthetic, sometimes as a day procedure. The surgeon will pass an endoscope (a tube with a video camera at one end) into your nostrils to allow them to see inside your nose and sinuses.
