ANOMALOUS ORIGIN OF OCCIPITOAURICULAR TRUNK FROM EXTERNAL CAROTID ARTERY

Open publisher page 0 citations

Abstract

Anomalies in the origin and branching pattern of the external carotid artery (ECA) are common. The level of the bifurcation of the common carotid artery (CCA) and the variations in the origin/branching pattern of the external carotid artery are well documented. In the present finding occipital and posterior auricular arteries were arising by a short common trunk from ECA on the left side. Knowledge of variations in the origin and course of branches of ECA is of importance in surgery. Surgeons need to be aware of the possibility of encountering such variations, as they may lead to difficulties in differentiating the branches of external carotid artery. This knowledge is also important for radiologists in the image interpretation of the face and neck regions.
