Measurements of the hypoglossal canal: The midpoint of the inner orifice of the hypoglossal canal is on average somewhat over 26 mm away from the opisthion. The distances of the canal centre come to approximately 30 mm, those of the outer canal orifice to 34 mm. The distance of the intracranial pores from each other amounts to 28 xmm. The medial portal for the extracranial pore is on an average 33 mm away from the portal of the opposite side, the lateral 40 mm from the lateral portal of the opposite side. The intracranial pore of the canal for the XII. nerve is situated on an average 13 mm in front of the posterior rim of the occipital condyle, the midpoint of the canal is 15.85 mm in front of this measuring zone, and the exit of the canal 19 mm. Some differences between the sexes and measurements of the postnatal increase of these distances have been included in this investigation. The diagnostic and surgical importance of the hypoglossal canal are discussed.
舌下神经管内口的中点平均距离枕骨大孔后缘略超过26毫米。神经管中心的距离约为30毫米，外口的距离为34毫米。颅内孔之间的距离为28毫米。颅外孔的内侧入口平均距离对侧入口33毫米，外侧入口距离对侧外侧入口40毫米。舌下神经（第十二对脑神经）管的颅内孔平均位于枕髁后缘前方13毫米处，神经管中点位于该测量区域前方15.85毫米处，神经管出口位于前方19毫米处。本研究纳入了性别差异以及这些距离出生后增长情况的测量。文中讨论了舌下神经管在诊断和手术方面的重要性。
