Functional Endoscopic Sinus Surgery (FESS) is a minimally invasive procedure used to treat chronic sinusitis and other sinus problems that don’t improve with medications. Using a thin endoscope with a camera, the surgeon opens blocked sinus pathways, allowing better drainage and airflow. This reduces symptoms like nasal congestion, headaches, and recurrent infections, improving overall quality of life.

What is Functional Endoscopic Sinus Surgery (FESS)?

FESS is a surgery performed through the nostrils, using an endoscope to see inside the sinuses. It removes blockages such as polyps or swollen tissue, restoring normal sinus function without external incisions.

Why is FESS done?

FESS is recommended for patients with:

  • Chronic sinusitis not responding to medical treatment
  • Nasal polyps
  • Recurrent sinus infections
  • Sinus blockage causing headaches, pressure, or breathing difficulty
  • Certain sinus tumors or structural problems
How is FESS performed?
  • The procedure is done under local or general anesthesia.
  • A thin endoscope is inserted into the nostril to visualize the sinuses.
  • Specialized instruments are used to remove obstructions and widen natural sinus openings.
  • No external cuts or scars are made.
What is recovery like after FESS?

Recovery is usually quick. Patients can often go home the same day or the next day. Nasal congestion and mild bleeding may occur for a few days. Most people return to normal activities within a week, though complete healing may take 4-6 weeks. Regular saline rinses and follow-up visits are important for the best results.

What are the risks of FESS?

FESS is safe, but rare risks include bleeding, infection, scarring, or injury to nearby structures (like the eye or skull base). Choosing an experienced ENT surgeon minimizes these risks.

How successful is FESS?

Most patients experience significant relief of sinus symptoms, improved breathing, fewer infections, and better quality of life. However, maintaining sinus health with proper medications and lifestyle changes remains important after surgery.
