| Abstract | This study aims to analyze the incidence of variations in the origin of the superior thyroid artery (STA) in Thai people and the vertical distances from the origin sites of the STAto the level of carotidbifurcation(CB).A total of 220 carotids were retrospectively investigated.The 110 carotid arteries and branches were examinedin 55 embalmed cadavers. The110 carotid angiographs based on 2D digital subtraction and 3D rotational angiography examinations from 55 patients were analyzed.Thedata fromboth investigations showed the origin of the STAfrom the external carotid artery(ECA) in 26.8%, including branches of the thyrolingual trunks in 1.4%, whereasits origin at the CB level and the common carotid artery(CCA) was found as high as73.2% of the samples. Regarding the sides, the STA origins from the ECA and the CB level weredominant on the right while that from the CCApredominated on the left. The average vertical distance fromexternal carotid originsiteof the STAtothe CBlevel was4.6?2.9 millimeters.The average vertical distance from common carotid origin site of the STAtothe CBlevel was6.1?5.5 millimeters. It is noted that the origin sites of the STAarose within a range of 10millimetersabove the CBto 10 millimetersbelow the CBlevel in 95.5% of the carotids investigated.Thepresent study revealed a relatively high incidence of the STA arising from the CCA and CB level in Thai. The surgical approaches of the neck at/below the CB level should be performed with great care of these STA origins in order to avoid accidental injuries. |
