Transoral laser microsurgery is another form of minimally invasive surgery used by several medical centers, including Washington University Siteman Cancer Center and Mayo Clinic to remove small and medium tumors through the mouth. It's occasionally used for larger tumors. Transoral laser microsurgery allows surgeons to remove tumors from the voice box with no external incisions. It also allows access to tumors that are not reachable with robotic surgery.
A microscope helps the surgeon clearly view the margins of the tumor, minimizing the amount of normal tissue removed or damaged during surgery. This technique helps give you as much speech and swallowing function as possible after surgery.[1][2][3]
