Overview
Functional endoscopic sinus surgery (FESS) is minimally invasive surgery for serious sinus conditions. Healthcare providers use nasal endoscopes — thin tubes with lights and lenses — to ease your sinus symptoms without making incisions in or around your nose.
Why do people call it functional endoscopic sinus surgery?
Functional endoscopic sinus surgery is also called endoscopic sinus surgery. Some healthcare providers use the term “functional” because the surgery is done to restore how your sinuses work, or function.
When would I need functional endoscopic sinus surgery?
Your healthcare provider may recommend FESS if you have chronic sinus inflammation or a chronic sinus infection that doesn’t improve with medical treatments, such as antibiotics and medications to manage allergies.
You develop sinusitis when the tissue that lines your sinuses begins to swell, trapping mucus that typically flows through your sinuses and out through your nose. The trapped fluid can grow bacteria that can cause infections. Healthcare providers may also recommend surgery if you have nasal polyps.
How does my healthcare provider decide if I need functional endoscopic sinus surgery?
Your healthcare provider will review your medical history and do a physical examination. Tests they may use include:
- Nasal endoscopy. Your healthcare provider checks your nasal passages and your sinuses through an endoscope for signs of infection or inflammation.
- Computed tomography (CT) scan. This test helps your healthcare provider determine which parts of your sinuses are affected.
