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.

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.

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.

The complicated process of angiogenesis and remodelling which includes annexation and regression of vessels may give rise to variations in the branches of external carotid artery. The knowledge of variations in the branching pattern of external carotid artery (ECA) is important for surgical procedures in the neck region, such as radial neck dissection, catheterization, reconstruction of aneurysm, carotid endarterectomy and intervention radiology. The anatomical consequences of anomalous branching pattern of external carotid artery may have important clinical implications. A rare, common branch of the ECA, a thyro-linguo-facial trunk was found on right side in a 65 years old male cadaver during routine dissection. After giving a branch to thyroid gland as superior thyroid artery, this trunk ran forwards and medially as linguo-facial trunk and divided into lingual and facial arteries. The hypoglossal nerve was crossing the linguo-facial trunk.

Background: External carotid artery is the main artery supplying the structures of neck and face. Variability in the branching pattern of external carotid artery is important surgically and radiologically from the point of view of procedures carried out in that region. Purpose of the present study was to study the branching pattern of external carotid artery.Methods: Carotid triangle of the neck and the infratemporal fossa was dissected for studying the external carotid artery.Results: Generally the common carotid artery bifurcates at the level of upper border of lamina of thyroid cartilage. Level of bifurcation of common carotid artery may vary; it may arise at a lower level or at a higher level than its normal level of origin, which was observed in this study. Amongst the branches of external carotid artery like the superior thyroid artery, the facial artery, the lingual artery usually shows variations in their origin. These include origin of superior thyroid artery from common carotid artery, common trunk for facial and lingual arteries and many other different types of variations were seen in this study.Conclusions: Variant origins of the branches of external carotid artery are of significance in surgeries of thyroid, parotid gland, tongue as well as important in diagnostic procedures of head, neck, face region.

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.

Las anomalías en el origen y patrón de ramificación de la arteria carótida externa (ACE) son comunes. El nivel de la bifurcación de la arteria carótida común (ACC) y las variaciones en el origen / patrón de ramificación de la arteria carótida externa están bien documentados. En el hallazgo de las arterias occipitales y posteriores surgían de un corto tronco común de la ACE en el lado izquierdo. El conocimiento de las variaciones en el origen y curso de las ramas de la ACE  son de suma importancia en la cirugía. Los cirujanos deben ser conscientes de la posibilidad de encontrar estas variaciones, ya que pueden conducir a dificultades en la distinción de las ramas de la arteria carótida externa. Este conocimiento es también importante para los radiólogos en la interpretación de las imágenes de las regiones de la cara y el cuello.  Anomalies in the origin and branching pattern of the external carotid artery (ECA) are common. The level of the bifurcation of the common carotid artery (CCA) and the variations in the origin/branching pattern of the external carotid artery are well documented. In the present finding occipital and posterior auricular arteries were arising by a short common trunk from ECA on the left side. Knowledge of variations in the origin and course of branches of ECA is of importance in surgery. Surgeons need to be aware of the possibility of encountering such variations, as they may lead to difficulties in differentiating the branches of external carotid artery. This knowledge is also important for radiologists in the image interpretation of the face and neck regions.

Abstract the methods of dissection and analysis of angioCT’s. Each of the details was analyzed comparatively on both sides of the body assessing: the origin of the superior thyroid artery in relation to the carotid bifurcation, the face of the external carotid artery that gives origin and the traject of the artery from the origin to the glandular parenchyma. The origin of the superior thyroid artery was evaluated on a number of 64 cases, most frequently having its origin from the external carotid artery, an aspect met 53.125 % of cases, at a distance that was between 1-18 mm. In 28.125 % of cases the superior thyroid artery had its origin in the common carotid trunk at a distance of 1-10 mm caudal to the terminal bifurcation of the common carotid. In 18.75 % of cases, the thyroid artery originated from the carotid bifurcation, which thus ends up by trifurcation. The side of the vessel that emerges the superior thyroid artery was assessed on 42 cases; most commonly the superior thyroid artery having its origin on the medial face, an aspect found in 66.67 % of cases; in 23.81 % of cases originated from the posterior medial and only two cases (4.76 % of cases), both on the left side(8.70 % of cases on the left), the origin of the superior thyroid artery was located on the anterior, respectively faces of the common carotid artery. The traject of the superior thyroid artery was followed on 53 cases, in most cases the artery showing initially a horizontal traject (transverse) towards medially for 1-4 cm, then became obliquely downward, an aspect met in 28.30 % of cases and in 22.64 % of cases, the artery was obliquely downward from its origin. In 11.32 % of cases the traject was obliquely ascending and in 9.43 % of cases the artery was initially obliquely upward for 2-3 cm, after which became transverse. For the remaining 28.30 % of the cases we have met a number of other 5 different patterns of traject but in a small percentage for each of them (5.66% of cases).

The superior thyroid artery shows a great variability in what concerns its origin. Most often, it appears as an independent branch of the external carotid artery, as its first collateral branch, or directly from the common carotid or at its terminal level. The superior thyroid artery origin was evaluated on 144 cases, using as study methods the dissection (39 cases), the plastic injection (22 cases) and the CT angiography evaluation (83 cases). It was studied, by percentage, the originating artery of the superior thyroid artery, the relation to the bifurcation of the common carotid artery, the neighboring arterial branches and the surface of the external carotid on which originated, the caliber of the external carotid artery before and after the origin of the superior thyroid artery. Most commonly, in 89 cases (61.80%), we describe the origin of the superior thyroid artery from the external carotid artery; from the common carotid artery originated 31 superior thyroid arteries (21.53%); at the level of the bifurcation of the common carotid artery, the superior thyroid artery had its origin in 21 cases (14.58%); in 2 cases (1.39%) we encountered the superior thyroid artery originating from a thyro-lingual trunk and in one case (0.69%), we met a thyro-linguo-facial trunk. The superior thyroid arteries may originate as an independent artery or as arterial trunks in varying proportions. When the origin of the superior thyroid artery is from the terminal common carotid, we propose to use the expression of terminal branching or the common carotid artery trifurcation. The results of our study are similar to those found in international literature, with statistical differences that may be attributed primarily to the total number of cases on which we worked and also working methods or may be attributed to other causes, such as the geographic area where the study was conducted and the amount of time the results were obtained.
