You have had a rhinoscopy (examination of the paranasal sinuses).

The sinuses are cavities in the skull that are filled with air. They make the head lighter and influence the sound of the voice. Air is moistened and warmed up in the sinuses. The sinuses have an inner lining of a moist and smooth membrane. This inner membrane is also called the mucous membrane. The mucous membrane produces fluid. The sinuses are connected to the nose via an opening. As a result, fluid can run out of the sinuses into the nose.

An endoscopic examination involves a thin tube or scope being passed into the relevant paranasal sinus. It is usually possible to reach the relevant paranasal sinus through the opening or an incision inside the nose. However, access may also be obtained by drilling through the skull from the outside. There is a camera at the top of the tube or scope. This camera is used to transmit images to the outside during the examination. In this way, the inside of the relevant paranasal sinus can be viewed and assessed for any changes.
