Functional endoscopic sinus surgery (FESS) is a minimally invasive surgical procedure used to treat chronic sinusitis, nasal polyps, and other sinus conditions. The surgery is performed using a small camera (endoscope) inserted through the nostrils — no external incisions are required.
What is FESS?
FESS uses a thin, flexible telescope inserted through the nostrils to visualise and operate on the sinuses. The surgeon removes tissue, bone, or polyps blocking the sinus drainage pathways, restoring normal sinus function without any cuts on the face.
Conditions Treated
- Chronic sinusitis (recurring sinus infections)
- Nasal polyps
- Deviated nasal septum
- Sinus cysts and tumours
- Fungal sinusitis
- Nasal obstruction
Benefits of FESS
- No external scars or incisions
- Short recovery time
- High success rates for chronic sinus disease
- Improved sinus drainage and ventilation
- Can be combined with septoplasty or turbinate reduction
Frequently Asked Questions
How long does FESS take?
Most FESS procedures take between 1 and 3 hours depending on the extent of disease. It is performed under general anaesthesia as a day case or with one overnight stay.
What is recovery like?
Most patients return to office work within 1–2 weeks. Strenuous exercise should be avoided for 3–4 weeks. Some bleeding and crusting in the nose is expected in the first 2 weeks.
Is FESS covered by medical aid?
Most South African medical aids cover FESS. Please check with your scheme and obtain pre-authorisation before surgery.
