Regional blood flow of the canine vocal cord: the microsphere surface technique.
The vocal fold's microcirculation has been well described, but there are few reports regarding the blood flow to this region. A number of methods have been used to evaluate the blood flow to an organ system. Among the most sensitive is the microsphere surface technique, which has been used to measure blood flow in many organ systems, including the cochlea. In this study, the blood flow to the canine vocal fold was assessed using the microsphere surface technique. Overall flow was measured, as well as flow to the lamina propria and muscularis layers. The technique and the results are reported.
