| Abstract: | The height of the bifurcation ofthe common carotid is changeable inaccordeance with the different headpositions.In observation of 66 cases.the anatomic findings show that thebifurcation is apparently lower whenthe head is deviated from the centrethan in an anatomic position.Howe-ver,in 80% of the cases,the bifur-cations are located between the upperborder of the thyroid cartilage andthe surface of the greater cornu ofthe hyoid bone.In a deviated headposition,the initial part of the ext-ernal carotid artery revolves innerwardand in most cases it is on the frontal-inner side or inner side.Addition-ally,it is observed that the superiorthyroid artery in about 50% of thecases originates from the common ca-rotid artery. |
