FESS stands for functional endoscopic sinus surgery. This minimally invasive surgery is effective in removing sinus polyps and other types of abnormalities of the nose that cause significant breathing problems, including chronic sinusitis.
During FESS surgery, an ENT surgeon inserts an endoscope, a small tube with a camera attached, into the nasal cavity through a nostril. Utilizing the camera’s images, the surgeon can detect any abnormal tissue or polyps that are making it impossible for the sinuses to drain properly. The surgeon will remove or reposition these abnormalities with tiny, precision cutting instruments inserted into the nostril.
