Essential sources of arterial vascularisation in the head and neck region are the left and right common carotid arteries (CCA) and their branches. The left CCA (LCCA) originates from the arch of the aorta and the right CCA originates from the brachiocephalic trunk. In this case report, there was a bilateral higher division of CCA at the plane of the greater cornua of the hyoid bone, unilateral tri-ramification of the LCCA and the left external carotid artery (LECA), and the origin of the linguo-facial trunk and the pharyngo-occipital trunk from the LECA. An aneurysm formed in the distal part of LECA before its termination. In this case, we propose a novel categorization called the punnapatla classification for the anatomical variance branching forms of ECA. These kinds of variations are important to the surgeons, and anaesthetists, during the surgeries of the head and neck.
头颈部动脉血管化的主要来源是左右颈总动脉（CCA）及其分支。左颈总动脉（LCCA）起源于主动脉弓，右颈总动脉起源于头臂干。在本病例报告中，双侧颈总动脉在舌骨大角平面出现高位分支，左颈总动脉和左颈外动脉（LECA）单侧三叉分支，以及舌面干和咽枕干起源于左颈外动脉。在左颈外动脉末端之前的远端形成了一个动脉瘤。在本病例中，我们提出了一种名为蓬纳帕特拉分类的新分类方法，用于颈外动脉解剖变异分支形式。这类变异对头颈部手术中的外科医生和麻醉医生来说很重要。
