FESS - Functional Endoscopic Sinus Surgery
Functional Endoscopic Sinus Surgery (FESS) is a medical procedure for treating a recurring sinus infection (chronic sinusitis) or nasal polyposis. The procedure is conducted with the patient put under general anesthesia.
An endoscope is a small rod-like instrument which is 4 millimeters or less in diameter and has a light at its end. A range of lenses are used to get a clear view of all the corners around the nose. A powerful fibrotic light is used to get clarity on the nasal close-ups. Once the area is investigated properly, specially designed instruments, powered with suction debrides are used to enlarge the sinus openings and anything that blocks the sinuses, such as swollen mucosa or polyps, are cautiously removed. At times, other surgical procedures like septoplasty and turbinate reduction are performed along with Functional Endoscopic Sinus Surgery.

Before conducting the functional endoscopic sinus surgery, patients are injected with intravenous sedation and local anesthesia.The patient is then prepared for the surgery. If there is a need of an image guided surgery, then the relevant headset apparatus needs to be applied.
During the Procedure
- The medical procedure begins with the nose being decongested by injecting a mixed solution of lidocaine with epinephrine (the ratio is 1% lidocaine with 1:100,000 epinephrine). The solution is injected near the uncinated area at the lateral nasal wall. The injection is done using a 3-mL syringe.
- After this, the inlet as well as the anterior face of the middle turbinate is injected with the solution submucosally. If septoplasty is required, the septum is also injected.
