Abstract:
Leaders of small military units readily admit to deterioration or even loss of voice during training and field exercises. Degradation of voice quality can severely impair field communication, and could potentially adversely affect a leaders ability to safely and effectively command his/her unit. Frequently, such voice changes resolve only after prolonged voice rest, and repeated episodes have led to permanent vocal cord pathology and socially unacceptable voice quality in some individuals. Anatomic changes in the vocal cords following periods of acute and chronic voice abuse have been previously documented in the literature to include edema, nodules, polyps contact ulcers, hemorrhage and scarring (1,2). No studies to date, however, have addressed the chronology of voice and vocal cord changes that occur during voice abuse. A clear understanding of the pathophysiological changes that occur during an episode of voice abuse may be helpful in developing strategies to combat voice impairment and vocal cord injury.
