Functional endoscopic sinus surgery (also known as FESS) is a minimally invasive surgery carried out to treat some of the causes of chronically blocked sinuses (also known as sinusitis).
FESS is a minimally invasive surgery carried out to treat some of the causes of chronically blocked sinuses.
FESS surgery is used to treat chronic sinusitis, which is caused by blockages in the nasal passages.
Your Consultant will tell you how long you should avoid eating and drinking beforehand. Before the FESS operation, you’ll be given a nasal spray to reduce the thickness of the lining in your nose.
During your FESS surgery, a thin endoscope will be inserted into your nose to help your surgeon see into your sinuses and insert small surgical instruments. There’s no need to make any incisions on the outside of your nose.
The surgery may involve removing any tissue, such as nasal polyps, that’s blocking your sinus.
FESS surgery is normally performed under a general anaesthetic, which means you’ll be asleep during the operation. You’ll be able to go home the same day, but you should arrange for someone to drive you home from the hospital.
After the surgery you may have packing inserted into your nose to stop any bleeding. This should be removed the following morning. If your nose starts bleeding again, you should pinch the soft part of the nose, apply an ice pack and rest.
You’ll need to avoid blowing your nose hard for a few days, but gentle sniffing will do no harm. A nasal spray may help clear your nasal passages.
You may need a few days off work and strenuous exercise should be avoided for a week or two.
