Functional endoscopic sinus surgery (FESS)

Functional endoscopic sinus surgery (FESS)

Functional endoscopic sinus surgery (FESS) is the mainstay in the surgical treatment of sinusitis and nasal polyps.

FESS is a relatively recent surgical procedure that uses nasal endoscopes (using Hopkins rod lens technology) through the nostrils to avoid cutting the skin. Telescopes with diameters of 4mm (adult use) and 2.7mm (pediatric use) and with a variety of viewing angles (0 degrees to 30, 45, 70, 90, and 120 degrees) provide good illumination of the inside of the nasal cavity and sinuses. High definition cameras, monitors and a host of tiny articulating instruments aid in identifying and restoring the proper drainage and ventilation relationships between the nose and sinus cavities. All the sinuses can be accessed at least to some degree by means of this surgery: The frontal sinuses located in the forehead, the maxillary sinuses in the cheeks, the ethmoid sinuses between the eyes, and the sphenoid sinuses located in the back of the nasal cavity at the base of the skull
