Abstract

The preservation of the spinal accessory nerve represents a key goal in head and neck oncologic surgery during selective neck dissection. This study aims to illustrate the anatomical variants of the XI cranial nerve, delving into the relationship between the spinal nerve and the internal jugular vein, as well as the surgical implications. Two cases of patients who underwent oncologic surgery with neck dissection are described. Both cases found the spinal accessory nerve passing through the fenestration of the internal jugular vein. Alongside this case series, an independent literature review was conducted using the Medline and PubMed databases. In the majority of cases (67% - 96%), the spinal accessory nerve traces a lateral course to the internal jugular vein. Less frequently, the XI cranial nerve courses medial to the internal jugular vein. More rarely, as described in this case series, the nerve crosses through the fenestration of the vein (0.48% - 3.3%).

摘要

脊髓副神经的保留是选择性颈清扫术中头颈部肿瘤外科手术的关键目标。本研究旨在说明XI颅神经的解剖变异，研究脊神经与颈内静脉的关系,以及手术的影响。描述了2例接受颈淋巴结清扫术的肿瘤手术患者。两种情况下都发现脊髓副神经穿过颈内静脉开窗。除了这个案例系列，使用Medline和PubMed数据库进行独立文献综述.在大多数情况下（67％-96％），脊髓副神经向颈内静脉的外侧延伸。不那么频繁,XI颅神经向颈内静脉内侧延伸。很少,如这个案例系列所述，神经穿过静脉开窗（0.48％-3.3％）。
