抄録
A computer system was introduced for quantitative evaluation of laryngeal images in normal volunteers and laryngeal paralysis patients. The subjects consisted of 10 normal volunteers and 10 patients with unilateral laryngeal paralysis (5 median fixation cases and 5 paramedian fixation cases). For phonatory examination, the sustained vowel /e/ with an easy phonation level was used. A glottal area was measured in digitized laryngeal stroboscopic images and normalized by the square of the vocal fold length. The average glottal area was defined to be as the average of the maximum and the minimum normalized glottal areas. In laryngeal paralysis patients, the average glottal area became larger as the paralyzed vocal fold position deviated from the median. Furthermore, the observation methods for vocal fold vibration was reveiwed and discussed. It emphasized that laryngeal stroboscopy was the most useful clinical testing methods.
