Neuro Endoscope

This video demonstrates how the endoscope works, and how it has revolutionized surgery for pituitary tumors and other abnormalities at the base of the skull.

An endoscope is a slender rod with a camera on the end of it, which provides high resolution visualization of the structures in front of it.  It has a wide field of view, and with a mirror system, one can see even at a 90 degree angle. Most people are familiar with endoscopes and their use in gallbladder surgery, where surgery has been transformed from use of a very large incision to using very small incisions through which the endoscope is placed to perform the surgery successfully. Advances in camera chip technology has allowed us to design Neurosurgical endoscopes that are approximately 1/10 of an inch in diameter. The small size permits us to place these scopes through corridors into critical brain areas. Resolution of the image is as good as 1080P like a Blu-ray CD player. Instead of a large incision, we can place these endoscopes through tiny natural pathways, such as the nostrils. In this technique one can navigate through the nostrils and sinuses to the base of the brain, and remove tumors in areas that were previously either inaccessible, or could only be reached using very high risk techniques.
