Nasal and nasopharyngeal endoscopy is an examination performed to investigate the interior of the nasal cavity. To carry out the examination, ENT Surgeon in Athens Dr. Olga Papadopoulou uses an endoscope with a diameter of 4 millimeters, which is a long thin tube with a camera and a light at the end, which she inserts into the nasal cavity in order to thoroughly examine its interior. The camera captures video images and displays them instantly on a high-definition screen. This can help diagnose and treat a number of conditions involving the nasal cavity. Endoscopy provides a magnified and detailed view of the area inside the nose.
