Functional Endoscopic Sinus Surgery (FESS)


A common surgical option for clearing blocked sinuses is endoscopic sinus surgery (ESS), which removes bone and tissue from the nose to enlarge the sinus opening. The original surgery was designed to remove all of the nasal mucosa from the sinuses in order to prevent inflammation. However, it was found that this actually caused worsening of symptoms with scarring.

Today, functional endoscopic sinus surgery is the most common procedure performed around the world to assist in the treatment of chronic sinusitis. The surgery is designed to be “mucosal sparing” so that the sinuses continue to function normally following surgery. The end goal is to enlarge the sinus openings in order for better penetration of topical medication.

*It is important to note that Balloon sinuplasty and FESS do not CURE sinusitis as this is a chronic disease. These procedures do, however, improve the ability to treat the condition and reduce symptoms and rates of infection.
