ABSTRACT
The superior thyroid artery (STA) is the chief artery which supplies blood to the thyroid gland, upper part of larynx and the neck region. The knowledge of variations in the origin of STA is important for surgical procedures in the neck region, such as radical neck dissection, catheterization, reconstruction of aneurysm, carotid endarterectomy and intervention radiology. The surgical anatomy of the STA was studied in 50 formalin preserved cadavers between the age of 40 to 60 years. A detailed review of literature was done to enlighten the surgical, radiological and clinical importance.
