• The ischemic change of the vocal fold on phonation was studied with an oxygen electrode using the canine vocal fold. Oxygen pressures of a limited area of the vocal fold were measured in the lamina propria and vocal muscle at the middle of the membranous portion. The results are summarized as follows: oxygen pressure in each area decreased on phonation as compared with respiratory movement, an ischemic change of the vocal fold occurred on phonation, and the response in the lamina propria was less than that of the vocal muscle.
