Details of the course of the accessory nerve and the pattern of the cervical contributions to the nerve are essential for planning neck dissection. Based on a recent anatomic description, a technique was devised to preserve the distal accessory nerve; the theory advanced was that the trapezius was supplied by motor fibers from the cervical plexus, which join the accessory nerve in the posterior triangle. Dissections were performed on 23 cadavers to test such a theory. The course of the accessory nerve in the neck was mapped in each dissection, and landmarks for use during surgery determined. Cervical contributions to the nerve usually joined deep to the sternocleidomastoid, and not in the posterior triangle. Branches from the cervical plexus, independent of the accessory nerve, entered the trapezius in the posterior triangle. None of the bilateral dissections showed symmetry of the cervical contributions.
副神经的走行细节以及颈部对该神经的贡献模式对于规划颈部清扫术至关重要。基于最近的解剖学描述，设计了一种保留副神经远端的技术；提出的理论是斜方肌由颈丛的运动纤维供应，这些纤维在颈后三角与副神经会合。对23具尸体进行了解剖以验证这一理论。在每次解剖中绘制了副神经在颈部的走行，并确定了手术中使用的标志。颈部对该神经的贡献通常在胸锁乳突肌深面会合，而非在颈后三角。来自颈丛的分支独立于副神经，在颈后三角进入斜方肌。双侧解剖均未显示颈部贡献的对称性。
