Anatomical study of high bifurcation of common carotid artery in human cadavers

Abstract

Aim and Objectives: The present research was carried out with an objective to study the level of bifurcation and its anatomical variations of common carotid artery (CCA). Methods: Fifty human cadavers (24 males and 26 females) were dissected and the level of bifurcation and its anatomical variations of CCA were noted and results were analyzed statistically. Results: The level of bifurcation of CCA at the superior border of thyroid cartilage was noted in 68 % of cases while higher and lower level of bifurcation was seen in 22% and 10% of the specimens respectively. High and low level bifurcation of CCA was highly significant on right side compare to left. Conclusion: The bifurcation of common carotid artery need not always be at the level of upper border of thyroid cartilage. It can be at either higher or lower in origin, higher being more common. The awareness in the variation of bifurcation level is necessary to avoid undue complications during the surgeries and procedures done in head and neck region.
