ABSTRACT

SUMMARY:

The superior laryngeal artery is the primary vessel providing the blood supply to the larynx. Commonly, it is derived from the superior thyroid artery. Different variations in the origin have been described in the current literature; knowledge of such variations is crucial for various surgical interventions of the larynx and surgical procedures in the lateral region of the neck regarding the carotid triangle. It should be noted that radiological studies, such as selective angiography of the thyroid gland, can also be misleading in cases of variations. Herein, we describe a case of bilateral superior laryngeal artery originating directly from the external carotid artery of the neck. The arteries at first have a transverse course and then pierce through the thyrohyoid membrane alongside internal laryngeal nerves. Moreover, we also review the known variations in the origin of the superior laryngeal artery and propose a new classification of all known variations.
RESUMEN
RESUMEN La arteria laríngea superior es el vaso principal que proporciona el suministro de sangre a la laringe. Comúnmente, se deriva de la arteria tiroidea superior. Han sido descritas diferentes variaciones en su origen y el conocimiento de éstas resulta crucial para las intervenciones quirúrgicas realizadas en la laringe, como también en los procedimientos quirúrgicos que se llevan a cabo en la región lateral del cuello, respecto al triángulo carotídeo. Cabe señalar que los estudios radiológicos, como la angiografía selectiva de la glándula tiroides, también pueden ser engañosos en casos de variaciones anatómicas. Aquí, describimos un caso de arteria laríngea superior bilateral que se originaba directamente de la arteria carótida externa. Las arterias al inicio tenían un curso transversal y luego atravezaban la membrana tirohioidea junto con los nervios laríngeos internos. Revisamos también las variaciones conocidas en el origen de la arteria laríngea superior y proponemos una nueva clasificación de todas las variaciones conocidas.
