Why is it important?
Common Carotid arteries (CCA) provides major sources of blood to head and neck by giving two terminal branches, external and internal carotid arteries, at the level of superior border of thyroid cartilage in carotid triangle. During routine dissection in Department of Anatomy, Shadan institute of Medical Sciences, Dr VRK Womens Medical college and we observed variations in three specimens. In one specimen we observed a higher division of External Carotid artery (ECA), near to the angle of mandible and in two specimens, we observed linguofacial trunk bilaterally. Knowledge of such variations are important for surgeries during plastic and reconstructive surgeries of head, neck and face to avoid iatrogenic injuries and for radiologists for interruption of angiograms of face and neck regions.
