Functional Endoscopic Sinus Surgery (FESS)

A. What is FESS?

FESS stands for Functional Endoscopic Sinus Surgery. This operation is performed through the nose and is aimed at treating nasal polyps and diseases of the Para-nasal Sinuses. The specific procedure varies depending on the symptoms you have and the findings on your CT scan. Thus it is imperative you bring any external CT scans with you on the day of surgery. FESS is often combined with a septoplasty to straighten the nasal septum and allow better access to the sinuses deeper in the nose.

B. How is it done?

You will be admitted on or a day before your surgery and will stay at least 48 hours in hospital. Before the operation you will seen by members of the surgical team and the anesthetist. The operation is performed with you asleep under a general anaesthetic for approximately 1 – 2 hours. You will wake up in the recovery room usually with some packing(not always) in the nose to prevent early post-operative bleeding. After an overnight stay and prior to discharge, you will be seen by the surgeon. If you have a nasal pack, this is removed (uncomfortable for a few seconds and often accompanied by bleeding for approx 30 minutes). Discharge medications can vary but will include pain relief tablets, antibiotic tablets in some instances, and usually a salt-water based nasal rinse to help ease the degree of crusting in the nose. Please follow the directions from the pharmacist.

C. Possible complications of hernia repair

The surgery is usually safe and uncomplicated however it is important that you are aware of the risks of the procedure. General complications such as nausea, vomiting, sore throat and drowsiness may occur as a result of the anesthetic. Serious drug reactions related
to the anesthetic are very rare.

Specific problems:

  • Bleeding – is common postoperatively and soon settles. Occasionally a pack will need to be reinserted to stop bleeding.
  • Infection – can occur in the skin or mucosa of the nose. If you have any pus-like discharge or are concerned about infection please report this to the surgical team.
  • Damage to the orbit (eyes) < 1% – A thin plate of bone separates the nose from the Eye-socket. If this is damaged then bleeding or infection can occur in the eye socket leading to severe pain and double vision. If this occurs you must contact the hospital urgently
  • Damage to the roof of the nose/floor of the brain < 1% – A thin plate of bone separates the nose from the front of the brain. Very rarely a crack can be made in this bone resulting in either a leak of CSF (thin watery fluid) from around the brain or bacteria travelling up and around the brain. If you develop any symptoms of severe headaches, fevers, neck stiffness or light sensitivity – then you must contact the hospital urgently.
