UW Health surgeons at UW Hospital and Clinics in Madison, Wisconsin, perform transoral laser microsurgery (TLM), a procedure to remove tumors of the larynx and throat using a precise carbon dioxide laser beam.


The Transoral Laser Microsurgery Procedure

  • The transoral laser microsurgery procedure lasts two to four hours, with the patient under general anesthesia.
  • The surgery is performed using an endoscope, which is inserted through the mouth. Using a specialized microscope, the surgeon is able to clearly view the tumor and surrounding tissue.
  • The surgeon uses a precise, carbon dioxide laser beam to cut the tumor away from the surrounding healthy tissue. The beam itself creates minimal heat energy, limiting damage to the tissue surrounding the tumor.

About the Laser


The laser beam is an ideal way of removing tumors because it is coupled with a microscope, allowing more exact removal of tumors. This degree of precision is especially important for tumors of the throat and larynx because even minor damage to the surrounding tissue can have a significant impact on speech and swallowing.


The Difference of Minimally Invasive

  • Excellent tumor visualization
  • Minimizes damage to speech and swallowing
  • Faster recovery
  • Less pain after surgery
  • Fewer complications
  • Leaves no externally-visible scar
