Laser surgery is surgery that uses a beam of laser light, rather than other instruments, to cut, dissect, remove, and so forth. The beam of light has advantages over other cutting instruments, such as scalpel or scissors. First, at the same time that it cuts, it tends to seal off tiny blood vessels and reduce bleeding. Second, it may be especially useful in endoscopic surgery, where there is not a lot of room for instruments. Third, it is very precise. Both the microspot carbon dioxide laser and the RevoLix laser used at our practice have minimum spot sizes of about 1/5 of a millimeter.

Laser Surgery for Bilateral Vocal Cord Cancer
Laser Removal of Vocal Cord Cancer with Bilateral Disease
For treatment of early vocal cord cancer, both laser excision and radiotherapy are in competition as good treatment modalities. See also Early Vocal Cord Cancer: Remove with a Laser, or Radiate? Often, radiation is used when disease is bilateral, in the interest of preserving voice. This is an example of the ability to do fairly extensive laser surgery bilaterally, yet preserving good voice. This man had a friend who had severe difficulty with radiation, and he was therefore opposed to that option.
