UNVER DOGAN, Nadire et al. Unilateral Variations of Vessels and Nerves in the Neck. Int. J. Morphol. [online]. 2010, vol.28, n.3, pp. 963-966. ISSN 0717-9502. doi: 10.4067/S0717-95022010000300049.
Variations of vessels and nerves in the left neck side, of 65 year old male cadaver, during the routine dissections, were detected. It was observed that the linguofacial trunk originated from external carotid artery and that the ascending pharyngeal artery originated from the occipital artery. It was determined that after the laryngeopharyngeales rami originated from the superior cervical ganglion, the branch wound around the origin of the superior thyroid artery. As an additional variation, the internal jugular vein divided. The cervical ansa and the inferior belly of the omohyoid muscle passed through the parts of the vein. We think that these type of variation can entail important difficulties during radiologic and surgical procedures of the neck region. To know these anatomical variations, is important for the anatomist and surgeons.
