What is Functional Endoscopic Sinus Surgery (FESS) primarily designed for?

• A. A to remove large sinus tumors
• B. B to treat serious cases of inflamed, infected, and blocked sinuses
• C. C to perform cosmetic surgery on the nose
• D. D to diagnose sinus disorders only

Answer: (B)

Functional Endoscopic Sinus Surgery (FESS) is primarily designed to treat serious cases of inflamed, infected, and blocked sinuses. This surgical technique improves sinus drainage and function by addressing the underlying issues that cause chronic sinusitis and other inflammatory conditions. By using an endoscope, surgeons can visualize the sinus passages and apply targeted interventions, such as removing polyps or diseased tissue, which helps restore normal drainage pathways.

The focus of FESS is on enhancing sinus function rather than removing tumors or performing cosmetic procedures, which makes it distinct in its application. It is not solely diagnostic; while it can provide some insights into sinus disorders, the primary purpose is therapeutic. Thus, the efficacy of FESS lies in its ability to alleviate symptoms and improve quality of life for patients suffering from chronic sinus conditions.
