Hypoglossal-facial nerve transfer is a standard technique for facial-palsy reconstruction. The fascicular anatomy of the hypoglossal nerve may be important in determining strategies, when attempting to minimize atrophy of the tongue. The present study investigated hypoglossal fascicular anatomy by histomorphometric analysis of 10 human hypoglossal nerves. The nerve demonstrates a monofascicular topography in its proximal third and mid portions, becoming polyfascicular only in its distal third. The mean number of fascicles in the distal portion is 5.0, compared to 1.1 in the proximal and mid portions (p < .01). The mean number of myelinated axons in the hypoglossal nerve is 9200.
舌下神经-面神经吻合术是面神经麻痹重建的标准技术。在试图尽量减少舌萎缩时，舌下神经的束状解剖结构对于确定手术策略可能很重要。本研究通过对10条人类舌下神经进行组织形态计量学分析，研究了舌下神经的束状解剖结构。该神经在其近端三分之一和中部呈单束形态，仅在其远端三分之一处变为多束形态。远端部分的束平均数量为5.0，而近端和中部为1.1（p < 0.01）。舌下神经中髓鞘化轴突的平均数量为9200。
