FESS restores natural drainage of the sinuses using endoscopes through the nose. It is the gold-standard treatment for chronic sinusitis and nasal polyps that do not respond to medicines.
Functional Endoscopic Sinus Surgery (FESS)
Minimally invasive sinus surgery to open blocked sinuses and remove nasal polyps.


About Functional Endoscopic Sinus Surgery
When is it recommended?
- Chronic sinusitis
- Nasal polyps
- Loss of smell
- Persistent facial pain & post-nasal drip
How the procedure is done
- 1
CT scan & planning
A CT scan of the sinuses maps the blockage and the safe surgical path.
- 2
Endoscopic access
Thin endoscopes are passed through the nostrils — no cut on the face.
- 3
Opening the drainage pathways
Blocked sinus openings are widened and polyps or diseased tissue removed, preserving healthy lining.
- 4
Post-operative cleaning
Saline rinses and endoscopic cleaning at follow-up keep the sinuses open while healing.
Benefits
Recovery & aftercare
Expect nasal blockage and some crusting for 1–2 weeks. Regular saline rinses are essential. Follow-up cleaning visits are an important part of a good long-term result.
