Functional endoscopic sinus surgery (FESS) is a surgical procedure that is performed to treat chronic sinusitis, a condition in which the lining of the sinuses becomes inflamed, causing symptoms such as congestion, facial pain, headaches, and difficulty breathing. FESS is a type of endoscopic sinus surgery that is less invasive than traditional sinus surgery and involves using a thin, flexible tube with a camera on the end (endoscope) to visualize the sinus cavities and remove obstructions or diseased tissue.
During the FESS procedure, the surgeon inserts the endoscope into the nasal passages and sinuses to view the area and guide surgical instruments. The surgeon may remove tissue or bone that is obstructing the sinuses or causing inflammation, and may also widen the openings between the sinuses and nasal passages to improve drainage and airflow.
FESS surgery is usually performed on an outpatient basis under general anesthesia, and recovery time varies depending on the extent of the surgery and the patient’s overall health. Most people are able to return to work and normal activities within a few days to a week after the procedure.
FESS surgery has a high success rate and can significantly improve symptoms and quality of life for people with chronic sinusitis. However, as with any surgery, there are risks involved, including bleeding, infection, and complications related to anesthesia. It is important to discuss the potential risks and benefits of FESS surgery with a qualified healthcare provider.
