“…In the human glottis, blood capillaries form a superficial network, while blood vessels with larger calibres are located below [23,25,34]; lymphatic microvessels form a superficial, close-meshed network, and a deep, wide-meshed network [16, 18-20, 44-47, 34]. This conforms to the situation in the porcine glottis.…”

“…In terms of function, authors have regarded the blood vascular organisation of the human glottis as being well suited to prevent disturbances of the circulation and metabolism of the tissues; such disturbances might be caused by vibration during phonation [23,25]. With regard to the above mentioned structural similarities, the same can be assumed also for the porcine glottis.…”

“…The most striking difference was related to the densities of the blood vascular networks: in humans, the blood-vascular network of the vocal fold has been reported to be denser than that of the vestibular fold [25]. This does not compare with the porcine glottis: Here, the CraF (topographically similar to the human vestibular fold, but presumably the main oscillator in porcine phonation [1]), displayed a vascular network wider than that of the CauF (topographically identical to the human vocal fold).…”

“…The shapes of the blood microvascular profiles in the porcine specimens suggested that the vascular orientation was mostly parallel to the long axes of the folds, entering the latter from the dorsal and ventral commissures; this has been described accordingly in the human glottis [23,25,34]. In terms of function, authors have regarded the blood vascular organisation of the human glottis as being well suited to prevent disturbances of the circulation and metabolism of the tissues; such disturbances might be caused by vibration during phonation [23,25].…”

“…In the human vocal fold, the lymph vascular system [16,34,[18][19][20][44][45][46][47] and the blood vascular system [23,25,34] have been studied intensively. However, topographical and stratigraphical relations have not been fully considered.…”

In order to gain a better understanding of the central and local control of laryngeal blood flow, the vascular innervation to the rat laryngeal muscles was examined. To visualize the vascular network, the animals were perfused with a gelatin/India ink solution. The larynges were removed and fixed. The superior laryngeal, cricothyroid, and inferior laryngeal arteries (all branch off the superior thyroid artery) were dissected in continuity into their respective muscles. Specimens were reacted in toto using immunohistochemical techniques for the presence of neuropeptide-Y (NPY), vasoactive intestinal peptide (VIP), calcitonin gene related peptide (CGRP), and neuronal nitric oxide synthase (NOS-1). Results show that all of the laryngeal vasculature is richly innervated by fibers containing these peptides. Qualitatively, the most prominent of these is NPY in association with the superior and the inferior laryngeal arteries, followed by VIP and NOS-1, and finally CGRP distributed equally on all the vessels. Immunopositive fibers are found along the entire course of the feeding arteries, beginning with the superior thyroid artery and continuing down to small arterioles into the terminal vascular beds. These peptides can act as vasodilators, vasoconstrictors, and/or neuromodulators and may work synergistically or antagonistically with other transmitters in controlling laryngeal blood flow. Their effects are dependent on the specific vascular bed in question, that is, in some areas they are vasodilators, in others vasoconstrictors, and in other neuromodulators. What effects they have on the laryngeal vasculature and how they interact within the larynx have yet to be determined.
