They all connect with your nose through tiny holes, called passages or ostia. The maxillary sinus is connected to the inside of the nose by a very small hole.
What has gone wrong?
Many different conditions could affect your sinuses. The mucous membrane lining of a sinus can swell because of allergy, infection, polyps or growths. Any swelling may block the opening of a sinus into your nose causing a headache, face pain or pain behind your eyes.
The various passages leading to the sinuses vary in shape and size. As a result, one sinus may be more prone to infection and blockage than another. X-rays or a CT scan of the sinuses will guide the surgeon to the parts of the nose causing trouble.
We aim to examine inside your nose and sinuses and treat any problems found. We use very narrow telescopes, called endoscopes, to do the examination. These endoscopes are about as thick as a drinking straw and have special lenses that allow us to see around corners. This helps the surgeon to see into the narrow passages deep inside your nose that lead into the various sinuses. We look into each of the narrow passages to find out which ones are blocked and causing trouble.
