Background and Objectives: Launay’s external carotid vein (ECV) is poorly represented in the anatomical literature, although it is an occasional satellite of the external carotid artery (ECA). We aimed to establish the incidence and morphology of the ECV. Materials and Methods: One hundred computed tomography angiograms were investigated, and ECVs were documented anatomically, when found. Results: Launay’s vein was found in 3/200 sides (1.5%) in a male and two female cases. In two of these cases, the ECV was a replaced variant of the anterior division of the retromandibular vein (RMV), and the facial vein (FV) ended in the external jugular vein. In the third case with the ECV, the RMV was absent and the common FV that resulted from that ECV and the FV drained into the internal jugular vein. The ECV could also appear as an accessory RMV, not just as a replaced one. Additional variants were found, such as fenestration of the external jugular vein (EJV), the extracondylar vein draining the deep temporal veins and an arterial occipitoauricular trunk. Conclusions: Surgical dissections of the ECA in the retromandibular space should carefully observe an ECV to avoid unwanted haemorrhagic events. Approaches of the neck of the mandible should also carefully distinguish the consistent extracondylar veins.

Different patterns of variations in the venous drainage have been observed in the past. During routine dissection in our Department of Anatomy, an unusual drainage pattern of the veins of the left side of the face of a middle aged cadaver was observed. The facial vein presented a normal course from its origin up to the base of mandible, and then it crossed the base of mandible posteriorly to the facial artery. Thereafter, it joined with the anterior division of retromandibular vein to form the common facial vein, which drained into the external jugular vein directly. Sound anatomic knowledge of the above variation in facial veins is essential to the success of surgical procedures in this region.

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.

Intractable Epistaxis

AbstractThe surgical management of intractable epistaxis by external carotid artery ligation may become complicated if there is a high bifurcation of the common carotid artery. Occlusion of the bleeding vessels by catheter embolization is described in a patient in whom exploratio n of the neck had failed to locate the external carotid artery.
