Functional Endoscopic Sinus Surgery (FESS) is a minimally invasive surgical procedure used to treat chronic sinusitis, nasal polyps, and blocked or poorly draining sinuses. The procedure is performed using a thin, high-definition endoscope that allows the surgeon to precisely visualize and remove obstructions within the nasal and sinus passages, all without any external cuts or scars.

By restoring normal sinus drainage and ventilation, FESS helps relieve nasal blockage, facial pressure, headaches, post-nasal drip, and recurrent sinus infections. Compared to traditional sinus surgery, FESS offers several advantages, including less pain, minimal bleeding, faster recovery, and improved breathing.

FESS is a safe and effective treatment option for patients who continue to experience symptoms despite medical management such as medications, nasal sprays, or antibiotics. The procedure significantly improves sinus health, overall comfort, and quality of life, allowing most patients to return to normal activities within a short period.
