Functional endoscopic sinus surgery. Technique.

Abstract

The purpose of functional endoscopic sinus surgery is to reestablish ventilation and mucociliary clearance of the sinuses. This goal is achieved primarily by the endoscopic removal of disease from key areas of the anterior ethmoid and middle meatus. In addition, the technique also offers the possibility of performing sphenoethmoidectomy with preservation of the middle turbinate. Localized irreversible disease in the maxillary sinus may be removed endoscopically with minimal trauma. The technique allows excellent visualization, and results in minimal morbidity and bleeding. Nasal packing is not required, and surgery can usually be performed on an outpatient basis using local anesthesia.
