Endoscopic sinus surgery - also called endoscopy or sinoscopy - is a procedure used to remove blockages in the sinuses (the spaces filled with air in some of the bones of the skull). These blockages cause sinusitis, a condition in which the sinuses swell and become clogged, causing pain and impaired breathing.
A thin, lighted instrument called an endoscope is inserted into the nose, and the doctor looks inside through an eyepiece. Much like a telescope with a wide-angle camera lens, the endoscope beams light into different parts of the nose and sinuses, allowing the doctor to see what is causing blockages. Surgical instruments can then be used along with the endoscope to remove the blockages and improve breathing.
This surgery does not involve cutting through the skin, as it is performed entirely through the nostrils. Therefore, most people can go home the same day.
Endoscopic sinus surgery is a relatively new procedure designed to increase the amount of air flowing through the sinuses and allow
- Relieve nasal blockages
- Relieve facial pain
- Improve breathing
- Improve the sense of smell and taste
Endoscopic sinus surgery is an effective procedure to correct:
Deviated septum, in which the partition separating the left and right sides of the nose is crooked
- Polyps, a noncancerous water-filled swelling
- Tumors, a swelling caused by an uncontrolled growth of cells
However, it seems to be less effective for those with post-nasal drip or allergies that are caused by airborne particles which cannot be avoided, such as dust and ragweed.
