Laser surgery of the larynx: the case for caution.

Laser surgery has been advocated for treatment of many laryngeal lesions. Although the CO2 laser has many advantages, its safe use requires special education of the surgeon and operating room team, and considerable surgical skill. Several dangers inherent in laser use for laryngeal surgery must be considered. These include vocal fold scarring secondary to thermal injury, loss of histopathologically important tissue through vaporization, airway fire and others. Laser-related complications must be considered whenever use of this instrument is contemplated.
