Dose-response characteristics of the human larynx with carbon dioxide laser radiation. 1980

A D Meyers, and D C Kuzela

The carbon dioxide surgical laser has become increasingly valuable in the management of various aerodigestive, gynecologic, and dermatologic problems. The histopathologic effects of laser radiation on human tissue have received only minimal attention, however. In an attempt to more precisely define the dose-response characteristics of the normal human vocal cord to carbon dioxide laser radiation, a normal larynx was exposed to varying intensities of laser radiation in situ and studied histologically. Tissue destruction varies with alterations in wattage and time exposure. The biologic effects of laser radioation are reviewed.

UI	MeSH Term	Description	Entries
D007013	Hypopharynx	The bottom portion of the pharynx situated below the OROPHARYNX and posterior to the LARYNX. The hypopharynx communicates with the larynx through the laryngeal inlet, and is also called laryngopharynx.	Laryngopharynx,Hypopharynges,Hypopharynxes,Laryngopharynges,Laryngopharynxes
D007834	Lasers	An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.
