Chronic rhinosinusitis with nasal polyps severely impairs quality of life, causing persistent nasal blockage, facial fullness, chronic headaches, and loss of smell. When optimal medical therapy fails to restore sinus drainage, Functional Endoscopic Sinus Surgery (FESS) is the international standard of care. Operating through the nostrils with fine fiber-optic cameras, the surgeon precisely removes polyps and enlarges sinus openings without making any facial incision.
