Assessment of Origin Characteristics of the Front Branches of the External Carotid Artery

Abstract

The neck region has a great vital value; its variations and known micrometric values are accepted as important orientation points during intervention. Micrometric values of the front branches of the external carotid artery and their relations to the surrounding structures and metric data pertaining to origin locations of the superior thyroid (STA), lingual (LA), and facial (FA) arteries were evaluated in 40 samples. As regards the evaluation of the branching types of the external carotid artery, the cases where the STA, LA, and FA originated as separate branches were 90%, linguofacial trunk cases were 7.5%, and thyrolingual trunk cases were 2.5%. The diameters of the STA, LA, and FA at their origins were observed to be 3.53 +/- 1.17, 3.06 +/- 0.65, and 3.35 +/- 0.68 mm, respectively. The distances from the origin of the STA to the carotid bifurcation of 3.29 +/- 4.27 mm, origin of the STA to that of the LA of 10.45 +/- 5.16 mm, and origin of the STA to that of the FA of 18.20 +/- 8.81 mm were found. The current findings may have serious implications for radiologic examinations, exploration of the neck, thyroid and parathyroid surgery, tracheotomy, and surgery of the larynx, pharynx, upper esophagus, pterygopalatine, and infratemporal fossa.

A Cross-Sectional Study of Superior Thyroid Artery in Human Cadavers

“…This is most common origin of superior thyroid artery. The superior thyroid artery origin from common carotid artery in the present study is 31.25% and similar in other studies [15,16,18,20,21] in a range of 1.51% to 52.3%. This is the second common position in present study.…”

A Study of the Common Origin of Lingual and Facial Artery From the External Carotid Artery

“…The mean level of origin of linguofacial trunk from carotid artery bifurcation was 1.3cm. The incidence of linguofacial trunk was reported by various authors .The lingual artery arises from a common trunk with the facial as a linguofacial trunk was found in 14% of the cases by Lappas [7], in 11.3% of the cases by Vishnu gupta et al [8], in 7.5% of the cases by Ozgur et al [9], in 15.38% of the cases by Abhijeet yadev et al [10] and it was found in 10% of the cases in the present study. Nirmala devi M et al reported that linguofacial trunk arose 3cm above the carotid bifurcation [11].…”

Variation in the Caudal Branches of the External Carotid Artery: Comparison of Sex and Side

“…Previous studies have shown that multiple ECA branching patterns exist (Gupta et al 2014, Hayashi et al 2005, Kamenskiy et al 2012, Kitagawa 1993, Klosek and Rungruang 2008, Lo et al 2006, LuČev et al 2000, Natsis et al 2011, Ozgur, Govsa, and Ozgur 2008, Sanjeev et al 2010, Shintani et al 1999, Toni et al 2004, Vázquez et al2009, Yonenaga et al 2011, Zümre et al 2005. Classic textbook representations of the ECA and the origins of its eight branches vary significantly depending on source (Drake, Vogl, and Mitchell 2005, Gilroy et al 2008, Moore, Dalley, and Agur 2009, Netter 2010.…”
