ABSTRACT:

Background: The common, internal and external carotid arteries are the major source of blood supply to the region of head and neck. The anatomy of the carotid arteries is of special interest to surgeons involved in the management of head and neck pathology. The presence of any anomalous origin and or course of these vessels is usually discovered as an incidental finding when imaging studies are performed during investigations of relevant clinical conditions.

Materials and Methods: The present study was conducted in the department of anatomy, University College of Medical Sciences (UCMS), Delhi, India. Twenty six formalin fixed head and neck regions belonging to either sex were dissected on both the sides. The level of common carotid artery (CCA) bifurcation and any variation from the normal in the branching pattern of external carotid artery (ECA) were noted and photographed.

Results: Out of twenty six head and neck regions studied (52 sides), variations in the level of bifurcation of CCA and branches of ECA were observed. In the present study, in 9 hemi sections of head and neck (Right=5: Left=4), CCA bifurcated above the normal level near to the angle of mandible. On the left side, in 7 specimens lingual and facial artery arose as a common trunk i.e linguo-facial trunk from ECA. In 3 specimens on the left side, superior thyroid artery (STA) arose from the CCA. Superior thyroid artery arose at the level of carotid bifurcation (CB) in 14 specimens (right = 8, left = 6).

Conclusion: The present study reports high bifurcation of CCA and variations in the origin of some of the branches of ECA. These findings may be utilised by vascular surgeons operating in the region of head and neck for preventing accidental injury to these vessels.

Key words: Carotid bifurcation, External carotid artery, Linguo-facial trunk, Superior thyroid artery.
