Microvascular Structure of the Larynx A Scanning Electron Microscopic Study of Microcorrosion Casts

Abstract

In this study, scanning electron microscopic observations were made of the microvasculature of the larynx of guinea pigs, rabbits and humans. The results showed that 1) The epiglottis being the most abundant of all laryngeal structures in vascular plexus, with some of the vessels perforating cartilage; 2) Blood vessels of the vocal cord course along its long axis showing undulation; arteriovenous anastomoses was noted; 3) In the arytenoid, blood vessels were found to be irregularly coursing and tortuous, thereby facilitating the purpose of smooth movements of this structure.
