ABSTRACT

Background and Aim: To study the variations in the site, mode, and the level of origin of the superior thyroid artery.

Materials and  Methods: This study was done in twenty five adult human cadavers. The superior thyroid artery was dissected on both sides and the following parameters including the source of origin, mode of origin and length of the artery till it’s termination into branches was noted.

Results:  In present study, the superior thyroid artery arose from the external carotid artery as a single trunk in 48% of specimens and its average distance of origin above the level of carotid bifurcation was 4.7mm. It arose as a single trunk at the level of bifurcation of common carotid artery in 44% specimens and from the common carotid artery below its bifurcation in 4% of specimens and the average distance of its origin below the level of carotid bifurcation was   13mm .   In 2% arises from external carotid artery as thyrolingual trunk  and in 2%  as thyrolinguofacial trunk . The average distance of origin of superior thyroid artery below the level of greater cornu of hyoid bone was  1.25 cm  and its average length was 3.3 cm.

Conclusion: The above information will be useful as reference for surgical procedures such as radical neck dissection and others like catheterisation, reconstruction  of aneurysm, carotid endarterectomy and interventional radiology.

KEY WORDS: Superior thyroid artery, common carotid artery, external carotid artery, carotid bifurcation, thyrolingual trunk, thyrolinguofacial trunk.
