What are the nasal sinuses?
Your sinuses (known as paranasal sinuses) are cavities inside your skull that are connected to your nose. Your sinuses are lined with a mucus-producing membrane and tiny hairs (cilia). The sinuses are the start of your airway, which includes your lungs. They are responsible for filtering, warming and humidifying the air we breathe so that it’s easier for our lungs to extract oxygen.
The mucus protects your nose from pollutants, germs, dust and dirt while the tiny hairs slowly move the mucus towards the back of your throat where it can be swallowed. You can produce up to 1.5 litres of mucous a day.
You have 4 pairs of nasal sinuses: maxillary, frontal, ethmoid and sphenoid sinuses.
Your sinuses can give you several problems which we call ‘sinusitis.’ It can be caused by inflammation, infection, dental problems or very rarely a tumour.
Sinusitis can cause problems with breathing, nasal discharge, disturbances in smell and taste, facial pressure and, very rarely, pain or headaches. Sinusitis is classified as acute (when symptoms resolve within 4 weeks) or chronic (when symptoms last for more than 12 weeks).
There are a number of treatments for sinus problems, however, if they haven’t worked you may need sinus surgery.
What is endoscopic sinus surgery?
Endoscopic sinus surgery involves removing soft tissue and bone to enlarge the opening of your sinuses, reduce inflammation and restore normal function. It allows better penetration of medical treatments, such as salt-water rinses and steroid sprays, into your nose and sinuses. It may also include removing nasal polyps, reducing nasal turbinates and straightening your nasal septum.
How is it done?
The surgery is usually performed through your nostrils. Your surgeon views the inside of your nose through a nasal endoscope which has a camera and light on the tip. After viewing the problem area, your surgeon works to widen the natural openings of your sinuses and create more space.
