FESS came into existence through the pioneering work of Drs. Messerklinger and Heinz Stammberger (Graz, Austria). Other surgeons have made contributions (first published in USA by David Kennedy in 1985)
Telescopes with diameters of 4 mm (adult use) and 2.7 mm (pediatric use) and with a variety of viewing angles provide excellent illumination of the inside of the nasal cavity and sinuses. High definition cameras, monitors and a host of instruments, and debrider blades aid in identifying and restoring the proper drainage and ventilation of the sinuses into the nasal cavities.
All the sinuses can be accessed 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.
This has revolutionized the management of chronic sinusitis
