摘　　要：研究舌下神经管及其毗邻结构的位置关系，为临床手术提供解剖学依据。方法：取成人头颅干骨标本60例（120侧），观察和测量舌下神经管及其毗邻结构的距离，并对双侧距离差别作统计学分析。结果：舌下神经管长度左（11．22＋1．67）mm，右（11．28士1．79）mm；其长轴与矢状面的夹角左45．19°士1．51°、右45．30°士1．33°；其长轴与枕髁长轴的夹角左62．44°土3．62°、右62．32°±3．64°；枕髁后缘到达舌下神经管内口、外口的距离左（9．38土1．67）mm、（16．18±1．97）mm，右（9．35±1．70）mm、（16．13±1．94）mm。颈静脉结节上表面到达舌下神经管内口的距离左（6．17士1．34）mm、右（6．22±1．36）mm；髁管的出现率为65％，2侧均含有双髁管1．67％。舌下神经管内口有骨性突起分隔者8．33％，内口分为双管者18．33％、三管者6．67％、二分管1．67％。以上结果左、右侧差异没有统计学意义。结论：熟悉舌下神经管及其毗邻结构的解剖知识，有助于临床相姜疼病的诊断和手术治疗肯禀的制宦。To provide anatomic basis for clinical surgery by studying the position relationship of the hypoglossal canal and its adjaeent structures. Methods： The distance between the hypoglossal canal and its adjacent struetures of 60 adult dry skullbase bones was observed and measured, and the data between bilateral sides were statistically analyzed. Results： The length of the hypoglossal canal on the left and right sides was （11.22±1.67）ram and （11.28±1.79）mm respeetively the angle formed by the long axis of the hypoglossal canal and the sagittal plane on the left and right sides were （45. 19±1.51） and （45. 30±1.33） degree respectively~ and the angle formed by the hypoglossal canal and the occipital con- dyle on the left and right sides were （62.44±3. 62） and （62.32±3. 64） degree respectively. The distance from the posterior edge of the occipital condyle to the intracranial orifice or the extracranial orifice of the hypoglossal canal was （9. 38 ± 1.67）mm, （16.18±1.97）mm （left）, （9. 35±1.70）mm and （16. 13±1.94）ram （right） respectively. The distance from the upper surface of the jugular tubercle to the intraeranial orifiee of the hypoglossal canal on the left and right sides were （6.17±1.34）mm and （6. 22＋1.36）mm respectively. The condylar canal was seen in 65%. Two sides in 1 ease （1.67%） were a double condylar canal. There were 5 sides （8. 33 %） on which the intracranial orifice of the hypoglossal canal was sep- arated by bony prominence, and 11 sides （18. 33%） on whieh the intraeranial orifice of the hypoglossal canal was separated into two parts, 4 sides （6. 67%） into three parts,and 1 side （1. 67%） into two-way branches. No significant differences were found on the left and right sides. Conclusion： The anatomy knowledge of the hypoglossal canal and its adjacent struc- tures is helpful for the clinical diagnosis and surgical plans.
