Anatomy Frontal sinus Ethmoid sinus Maxillary sinus Sphenoid sinus Ostia
Pathophysiology Sinus Disorders Anatomical Defects Inflammatory conditions such as chronic sinusitis
Diagnostic History and Physical CT Scans
Surgical Intervention The surgical intervention for FESS is to reestablish normal breathing and ability of mucus to be cleared from the sinuses. Due to inflammation, the mucus cannot be cleared from the sinus resulting in the formation of a mucocele and or a sinus infection
Special considerations Although you are going in an orifice of the body you should still keep instruments as sterile as possible Know how to change out lenses on the endoscope Chance of orbital hematoma being treated if it one is located

Procedural Steps The surgeon applies the topical anesthetic and injects the local anesthetic The endoscope is introduced into the nose The ostia of the sinus to be worked on is visualized and enlarged to facilitate drainage. The diseased tissue is visualized and excised Biopsy may be performed and polyps, if present, are excised. An Ethmoidectomy may be performed to create on large sinus cavity to promote drainage
Procedural Steps 8he surgeon may perform a sphenoidectomy if diseased bone was identified on the CT scan Endoscope is removed; antibiotic ointment is placed Mustache Dressing is applied
