Caption

Nasal polyp. Coloured 3D computed tomography (CT) scan of a large polyp (centre right) in the rear part of the left nasal passage. Polyps are tumours (growths) that occur on mucus membranes. Nasal polyps are removed if they turn cancerous or begin to obstruct the air flow. This is the view that would be seen by a nasal endoscope (rhinoscope) inserted into the nose. The thin area of tissue at centre is the septum, dividing the two nostrils. At left and right is the soft tissue and cartilage that makes up the nose. In the background is a mass of membranous tissue rich in blood vessels. This tissue filters, warms and moistens air as it passes through the nose towards the lungs.
