transoral robotic surgery (TRANZ-or-ul roh-BAH-tik SER-juh-ree)
Surgery in which a robot with arms is used to remove cancer from hard-to-reach areas of the mouth and throat. Cameras attached to the robot give a 3-dimensional (3D) image that a surgeon can see. The surgeon guides tools at the ends of the robot arms to remove the cancer. Also called TORS.
