Nasal polyp surgery. ENT surgeon (left) examining a patient's nasal polyp using a nasal endoscope. The position of the polyp in the patient's nose can be seen on a monitor (centre). The surgeon can remove this benign growth using a microdebrider (not shown). This is known as functional endoscopic sinus surgery (FESS). A nasal endoscope is a thin, fibre-optic tube that can be inserted into the nose to examine openings in the sinuses. It allows surgical procedures to be performed entirely through the nostrils, leaving no external scars, little swelling and only mild discomfort. Photographed at the West Middlesex Hospital, Twickenham, England.
