We studied the extra cranial portion of the internal carotid artery and structures associated with
it, which are vulnerable to iatrogenic injury during surgical approach to the neck region in 18
individuals. Distances from the origin of the artery to hypoglossal nerve and posterior belly of
digastric muscle were measured. The mastoid process and the hyoid bone were also used as
landmarks in locating the nerve and respective distances measured. Hypoglossal nerve and
posterior belly of digastric muscle crossed the ICA at variable positions with a mean distance of
10.1mm and 17.9mm respectively from the common carotid bifurcation. From the mastoid
process, the internal carotid artery ascends underneath the posterior belly of the digastric muscle
a third the distance to the hyoid bone. The external carotid artery is located lateral to the internal
carotid artery in 63.8% of the cases, posterior in 16.7% and anterior in 19.4%. The posterior
belly of digastric muscle and its attachments are key landmarks in identifying the internal carotid
artery and thus avoiding injury to vital neurovascular structures which may help structures, which
may help, improve clinical outcomes during surgery.
