• Arteria carotida externa
• Tronco linguofacial
• Vena yugular interna
• Variacion anatomica
• External carotid artery
• Linguofacial trunk
• Internal juguler vein
• Anatomic variation

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. Durante una disecci車n de rutina, fue obserada en el lado izquierdo del cuello de un cad芍ver de sexo masculino de 65 a os de edad variaciones anat車micas vasculares y nerviosas. Se observ車 que el tronco linguofacial se originaba de la arteria car車tida externa y que la arteria far赤ngea ascendente se origina en la arteria occipital. Se determin車 que los ramos laringofar赤ngeos originadas desde el ganglio cervical superior, giraban en torno al origen de la arteria tiroidea superior. Como una variaci車n adicional, la vena jugular interna se encontr車 dividida. El asa cervical y el vientre inferior del m迆sculo omohioideo pasaban a trav谷s de las partes de la dividi車n de la vena. Creemos que este tipo de variaciones supone dificultades importantes durante procedimientos radiol車gicos y quir迆rgicos de la regi車n del cuello, y por tanto, es importante que los cirujanos conozcan estas variaciones.
