Abstract :
Background: Evaluation of carotid bifurcation level and relationship of External Carotid Artery (ECA) with reference to adjacent anatomical landmarks is important in planning various surgical and radiological procedures related to the carotid arteries.
Aims and Objectives: The aim was to study the relationship of External Carotid Artery with reference to Adjacent Anatomical landmarks in cadavers.
Materials and Methods: 60 cadavers - 52 male and 8 female embalmed with 10% formalin were dissected over the period of two years for this study.
Results: The distance between the origin and the termination of ECA was found to be in the range of 25–70 mm on the right side and in the range of 25–68 mm on the left side. The distance between the origin of ECA and the carotid tubercle was found to be in the range of 23–50 mm on the right side and in the range of 22–48 mm on the left side. The distance between the origin of ECA and the angle of the mandible was found to be in the range of 18–30 mm on the right side and in the range of 20–32 mm on the left side.
Conclusions: The anatomical knowledge of relationship of External Carotid Artery with reference to adjacent anatomical landmarks is helpful for vascular surgeons to plan surgeries and prevent complications during various diagnostic and therapeutic procedures.
