Description

FESS is majorly performed to clear the hollow cavities of the skull in and around the nasal passages from chronic sinus infections. Hence the surgery is also referred to as sinus surgery. Sinuses are hollow craters present within the skull bones. They are situated behind the cheekbone or below the eyes and in the forehead region. The primary function of sinuses is to produce mucus that lines the nasal passages to keep from dust, irritants, and other pollutants. A healthy sinus is typically filled with air. While a blocked sinus is tucked with fluids and germs that multiply to develop sinus infections. FESS or Sinus surgery involves small incisions in and around the nose through which an endoscope (a device having a small tube, light, and camera) is inserted to clear the trapped fluid and bacterial infections.
