Endoscopic surgery of paranasal sinuses

Endoscopic surgery is a minimally invasive procedure, it is used to treat long-term (chronic) sinus infections or open the passages of the paranasal sinuses and allow adequate drainage into the nose. It is called an endoscopic procedure because the doctor uses an endoscope (a small rigid tube with a light and a camera lens at the end) to observe the inside of the nose; Generally, for the endoscope to move forward, small incisions or cuts are made inside the nose. The doctor can create new ducts or open existing ones by removing thickened polyps, cysts or mucous membranes.
