This study investigates the morphological-topographic anatomy of the Internal Jugular Vein (IJV) and its relationships with other vascular and neural structures in patients undergoing functional neck dissection. Thirty-two patients (27 males,emales; f 5 mean age: 63.03) were included. Preoperative computerized tomography (CT) imaging measured the transverse diameters ofat the IJV the os hyoidea and cartilago cricoidea levels, along with morphometric measurements such as the IJV position relative to themmon Co Carotid Artery (CCA) and the distance between the IJV and CCA. The IJV length and number of branches entering the IJV were also recorded. During dissection, the IJV's anatomical relationship with the Accessory Nerve (AN) was noted. Findings showed.7 that% 67 of IJV positions were lateral to the CCA, while 25.5 % were anterior, and 6.8 % were posterior. The most common IJV branchwas type the five-branch type (61 %). Right IJV diameters were larger than the left, with no significant differences observed betweenck sides ne and sexes. A positive correlation was found between the upper and lower IJV diameters. The distance between the IJV and CCAied, var with some measured at 1 mm and others at 4 mm. The majority of AN positions were anterior (55.9 %). Our study, which included measurements obtained both via CT imaging and during neck dissection, objectively clarifies the relative positions of theo the IJV t CCA, providing measurable guidelines for surgical practice. Significant anatomical variations between the IJV, CCA and ANpoe still significant risks during neck dissection surgeries and jugular vein catheterizations.
