Functional Endoscopic Sinus Surgery (FESS)Procedure

The rigid nasal Sinus endoscopy is a small tool that looks like a silver pencil, four millimeters or less in diameter and has a light on the end. It has lenses with several angles to enable see all corners of the nostril. This enables the surgeon have a comprehensive view of the nose and sinuses. The examination checks all the crannies and nooks of the nose, thus showing the exact location where the bone deformities are. With this, we are able to make a plan for the right treatment.

1. The endoscope is passed through your nostrils with a local anaesthetic during the diagnosis.

2. It is also used during operation in theatre, using general anaesthetic.

3. It is mainly used in outpatient clinic during diagnosis and follow ups.

4. In theater most work is done under direct vision with a strong headlight. The endoscope with angles is used to see around the corners inside your nose.

However, the tool does not help see inside of the sinuses, unless the openings are enlarged. In order to have better view of the sinuses, CT scan is required.

CT scan

This is a type of X-ray imaging which makes it possible for you to see the body clearer compared to x-ray. CT scan has the ability to split the image into thin layers, in order to pin point every point.


CT scanning has several limitations including:

1. It does not diagnose sinus problem, but offers information that can be interpreted by ENT specialist.

2. The scan only shows the condition of the sinuses and nose on the day it is taken.

3. In case you have had a head cold, the linings of the sinuses and nose will look abnormal.

4. If you get regular episodes of sinusitis, but you have not had one for some weeks the scan might look normal.

5. There is high risk of blindness as a result of damage of optic nerve during the surgical process.

A qualified radiologist will

1. Understand the kind of information that the ENT expert requires from the scanning process.

2. Ensure that the slices are carried out in the best way to give the information.

3. Give report in a focused and clinically relevant manner.

The best way the radiologist will understand what is needed is by getting regular feedback and discussing the cases with the surgeon. In addition, the radiologist keeps the surgeon informed with advances in imaging.

MRI scans are not as useful as CT because they do not show the detail of the fine bone. This is why it is used in rare conditions of sinus tumors.

How the operation is carried out

In most cases FESS operations are performed under general anaesthetic in the theater. This ensures that you get fully asleep within a few seconds. A plastic tube is put through your mouth into the windpipe to allow you to breath during the operation. No external cut is made because the surgery is performed through your nostrils.

1. A strong headlight and telescope is used to help view all the corners of your nostril.

2. The sinus openings are enlarged and anything that blocks the sinuses are removed using a specially designed fine bone, suction debriders, cutting instruments.

3. Procedures such as LASER vapourization and septoplasty are performed at the same time as FESS.

4. Stitches are self dissolving and internal.

5. The entire operation takes less than an hour.

6. At the end a pack of sponge dressing is put in each nostril for a few hours to soak the blood.
