dc.description.abstract | Knowledge of variations in branching of external carotid artery is important to minimise inadvertent injury
and confusion in identification during neck and craniofacial surgery and interventional neuroradiology.
These variations show ethnic differences. Procedures in head and neck are increasing but data on these
variations among black populations are scarce. This study therefore examined the branching pattern of
external carotid artery in a black Kenyan population. Two hundred and twenty-four common carotid
arteries of 112 black adult Kenyans were exposed by cadaveric dissection at Department of Human
Anatomy, University of Nairobi, Kenya. The sternocleidomastoid muscle and body of mandible were
removed and the external carotid artery and its branches exposed. The conventional pattern of branching
was observed in only 41.1% of cases. The variant patterns observed were trifurcation (26.8)%,
bifurcation (17.9%) and quadrifurcation (8.9%). There were 20 (5.3%) cases of early division. Linguofacial
trunk was observed in 44.7% cases. Frequency of variant branching pattern of external carotid
artery in the population studied is high. Interventional radiologists, vascular, craniofacial and neck
surgeons should be aware of these. Preoperative sonographic evaluation of the carotid arterial system
is recommended. | en_US |
