The motor fibers to the thyrohyoid muscle are provided by the anterior ramus of C1 via the hypoglossal nerve rather than via the ansa cervicalis. Knowledge of possible variations in the branching patterns of the nerves attached to the hypoglossal nerve is necessary to minimize iatrogenic injury to these structures during surgical procedures. We describe a rare anatomical variant of the nerve branch to the thyrohyoid muscle. To our knowledge, this particular variant has not been previously reported.
支配甲状舌骨肌的运动纤维由 C1 的前支通过舌下神经提供，而不是通过颈袢。了解附着于舌下神经的神经分支的可能变异模式对于在手术过程中最小化这些结构的医源性损伤是必要的。我们描述了一种支配甲状舌骨肌的神经分支的罕见解剖变异。据我们所知，这种特殊的变异以前尚未报道过。
