Endoscopic sinus surgery involves inserting a thin, lighted tube with a camera on the end into the nose so that your doctor can visually examine the area. Tiny surgical instruments are then inserted to remove the obstructive tissues. Endoscopic sinus surgery does not require any incision, as the whole procedure is performed through the nostrils.
Functional endoscopic sinus surgery (FESS) is the most common type of surgery for chronic sinusitis performed today. This minimally invasive procedure has significantly improved the results of sinus surgery. Advantages of FESS include a shorter recovery time, reduced risk of infection, decreased postoperative pain, and less scarring.
