Background: The superior thyroid artery (STA) is the dominant arterial supply of the thyroid gland, larynx and the neck. Knowledge of these variations is crucial for decreasing morbidity during the surgeries. The present study was undertaken to evaluate the frequency of usual anatomical variations in the origin of STA in human cadavers. Method: The origin of STA was studied by dissecting hundred human carotid specimens obtained from the formalin embalmed cadavers who were allotted to the undergraduate students for dissection in the Department of Anatomy. Results: STA arose commonly from external carotid artery (ECA) in 71 cases (71%), arising directly from common carotid artery (CCA) in 24 (24%) cases whereas only in 5 specimens (5%) it was arising at the level of bifurcation of CCA. On the right side STA was originated from ECA in 31(43.7%) and on left side it was 40(56.3%). STA was originated at bifurcation level in 5(100%) cases on right side and on left side no case was observed (0%). On right side STA was originated from CCA in14 (58.3%) cases and on left side in 10(41.6%) cases. Conclusion: The wide range of variations of the STA on its origin, course, branching patterns and relationship with adjacent structures is a common phenomenon. Thus, the deep knowledge concerning the origin and branching pattern of STA is essential in enhancing precision and decreasing morbidity related to the surgical and interventional radiological head and neck procedures.

The external carotid arterial system supplies the areas of head and neck region. The knowledge of possible anatomical variations occurring in branching pattern of external carotid artery is crucial especially in the surgeries of head, neck and face; as well as for interpretation of radiological investigations like angiograms. During routine dissection of head and region for undergraduate students we discovered common trunk for lingual, facial and ascending pharyngeal arteries. Also, the occipital artery is arising just before the common trunk from the external carotid artery. KEY WORDS: External carotid artery, branches, common trunk, occipital artery.

The common carotid arteries are the major source of blood supply to the region of head and neck. Normally external carotid artery gives eight branches in the region of neck. All of them arise independently as separate branches. In the present case, we found lingual and facial arteries arising from a common trunk i.e. linguofacial trunk from the front of external carotid artery on the right side. While on the left side, lingual and facial arteries were arising separately from external carotid artery. Such anatomical variations of external carotid artery are important for surgeons in surgeries of head and neck region and also for radiologists in the image interpretation of the face and neck region.DOI: http://dx.doi.org/10.3126/ijasbt.v1i3.8668 Int J Appl Sci Biotechnol, Vol. 1(3) 2013 : 154-157

BACKGROUND External carotid arteries account for a major share of arterial supply of head and neck regions. As variations are frequently observed in the branching pattern of external carotid artery, surgeons, radiologists and anaesthetists often encounter difficulties in various procedures of head and neck. The purpose of this study is to describe the variations in the branching pattern of external carotid artery as observed in South Indian population which definitely reduces its iatrogenic injuries associated with surgical and radiological procedures of head and neck. METHODS This is cross-sectional descriptive study. Bilateral neck dissection was done on twenty-two formalin fixed cadavers to study the branching pattern of external carotid artery during a period of two years in the Department of Anatomy in Government Medical College, Alappuzha. Common carotid, external carotid and internal carotid arteries were dissected. All the branches of external carotid artery were traced and the variations were noted. The distance between carotid bifurcation and point of origin of individual branches of external carotid were measured and statistically analyzed. RESULTS In the present study along with normal branching pattern of external carotid artery, variations like origin of superior thyroid artery from common carotid artery and also from carotid bifurcation were seen. A common linguofacial trunk and direct origin of superior laryngeal artery from external carotid artery were also observed. CONCLUSIONS Prior knowledge of the variations will be helpful to surgeons and anaesthetists while dealing with these vessels during procedures of head and neck regions.

Abstract Background The major arterial supply to the thyroid gland is from the superior and inferior thyroid arteries, arising from the external carotid artery and the thyrocervical trunk respectively. The external laryngeal nerve runs in close proximity to the origin of the superior thyroid artery in relation to the thyroid gland. The superior thyroid artery is clinically important in head and neck surgeries. Objectives To locate the origin of the superior thyroid artery, because wide variability is reported. To provide knowledge of possible variations in its origin, because it is important for surgical procedures in the neck. Methods The origin of the superior thyroid artery was studied by dissecting sixty adult human hemineck specimens from donated cadavers in a Department of Anatomy. Results The highest incidence observed was origin of the superior thyroid artery from the external carotid artery (88.33%), whereas origin from the common carotid bifurcation only occurred in 8.33%. However, in 3.33% of cases, the superior thyroid artery originated from the common carotid artery and in a single case, the external laryngeal nerve did not cross the stem of the superior thyroid artery at all, but ran ventral and parallel to the artery. Conclusions It is important to rule out anomalous origin of superior thyroid artery and verify its relationship to the external laryngeal nerve prior to ligation of the artery in thyroid surgeries, in order to prevent iatrogenic injuries. Moreover, because anomalous origins of the superior thyroid artery are only anatomic variants, thorough knowledge of these is decisive for head and neck surgeries.

✓ The authors present a patient with a complex vascular malformation composed of bilateral spontaneous carotid-cavernous fistulas (CCF's). The abnormality was supplied on the right side by the right external carotid artery (ECA) and the right internal carotid artery (ICA), and on the left side only by the left ICA. There was also an arteriovenous communication between the right ECA and the lateral sinus. Surgical embolization of both cavernous sinuses with oxidized cellulose was achieved on one side by direct puncture and on the other through one of its venous affluents, successfully occluding both CCF's and preserving the patency of both ICA's without any neurological deficit. The arteriovenous communication between the right ECA and the lateral sinus was occluded by embolization of the occipital artery and ligation of the right ECA.

AbstractDevelopmental anomalies in the origin and branching pattern of the external carotid artery are not common. The level of the bifurcation of the common carotid artery and also the variations in the origin/branching pattern of the external carotid artery are well known and documented. During a routine dissection of middle aged male cadaver in department of Anatomy in BP Koirala Institute of Health Sciences (BPKIHS) The clinically-relevant variations to be noted were the high origin and anomalous course of the facial artery, superior thyroid artery arising as a branch of Common Carotid artery, high origin of ascending pharyngeal artery, posterior auricular artery and direct glandular branches to the Submandibular gland. Such anatomical variations of external carotid artery are important for surgeons in surgeries of head and neck region and also for radiologists in the image interpretation of the face and neck region.

Unusual Origin

Thyroid surgeries are most common neck surgeries; hence thorough knowledge of the variations in blood supply of this gland to the surgeons is very important to prevent any alarming hemorrhage or iatrogenic damage. We found a variation in origin of superior thyroid artery on right side during routine dissection on an adult male cadaver in the Department of Anatomy, A.I.I.M.S, NewDelhi. Left superior thyroid artery was normal. Right side, superior thyroid artery was arising from common carotid artery instead of external carotid artery, just proximal to the bifurcation of common carotid artery. This variant branching pattern of superior thyroid artery is very rare. The inferior thyroid arteries did not show any unusual origin. Knowledge of such arterial variations related to the thyroid gland is immensely helpful to the surgeons to avoid damage of the vital organs in this region.

Common Trunk

The present study describes analytically a rare case in which lingual and facial arteries arise together from an external carotid artery in a common trunk. Thirty anatomic dissections were performed on 15 cadavers in the macroscopic laboratory in the Department of Anatomy of the Medical School of National and Kapodistrian University of Athens. One common trunk from which originated lingual and facial arteries was found. The frequency of this morphology is measured at 6 per cent. The length of the common trunk is measured at 7.3 mm between its origin and its diversion at the facial artery and lingual artery, its diameter at 2.8 mm, its distance from carotid bifurcation at 7.9 mm, and from the superior thyroid artery at 3.3 mm. At the left side of the neck region, facial and lingual arteries arose separately. The anatomic variations of the branching pattern of the external carotid artery and the micrometric values of the vessels are especially important as a result of the numerous operations performed in the neck region that implicate various specialties such as general surgery, head and neck surgery, plastic surgery, and maxillofacial surgery.

ABSTRACTVariations in the position of the bifurcation of the common carotid artery and the origin or branching pattern of the external carotid artery are well known and documented. Here, we report the trifurcation of the right common carotid artery in a male cadaver aged about 55 years. The right common carotid artery was found to divide into the external and internal carotids and the occipital artery. High division of bilateral common carotid arteries and a lateral position of the right external carotid artery at its origin were also observed in the same cadaver. There were two ascending pharyngeal arteries on the right side - one from the occipital artery and another from the internal carotid artery. The intraarterial approach is one of the most important routes for the administration of anticancer drugs for head and neck cancers. A profound knowledge of the anatomical characteristics and variations of the carotid artery such as its branching pattern and its position is essential to avoid complications with catheter insertion.
