Abstract：
OBJECTIVE: Minimally invasive atlantoaxial surgery offers the benefits of reduced trauma and quicker recovery. Previous studies have focused on feasibility and technical aspects, but the lack of comprehensive safety information has limited its availability and widespread use. This study proposes to define the feasibility and range of surgical safety using the intersection of the greater occipital nerve and the inferior border of the inferior cephalic oblique as a reference point.
METHODS: Dissection was performed on 10 fresh cadavers to define the anatomical reference point as the intersection of the greater occipital nerve and the inferior border of the inferior cephalic oblique muscle. The study aimed to analyze the safety range of minimally invasive atlantoaxial fusion surgery by measuring the distance between the anatomical reference point and the transverse foramen of the axis, the distance between the anatomical reference point and the superior border of the posterior arch of the atlas, and the distance between the anatomical reference point and the spinal canal. Measurements were compared using Student\'s t test.
RESULTS: The point where the occipital greater nerve intersects with the inferior border of the inferior cephalic oblique muscle was defined as the anatomical marker for minimally invasive posterior atlantoaxial surgery. The distance between this anatomical marker and the transverse foramen of the axis was measured to be 9.32 ± 2.04 mm. Additionally, the distance to the superior border of the posterior arch of the atlas was found to be 21.29 ± 1.93 mm, and the distance to the spinal canal was measured to be 11.53 ± 2.18 mm. These measurement results can aid surgeons in protecting the vertebral artery and dura mater during minimally invasive posterior atlantoaxial surgery.
CONCLUSIONS: The intersection of the greater occipital nerve with the inferior border of the inferior cephalic oblique muscle is a safe and reliable anatomical landmark in minimally invasive posterior atlantoaxial surgery.

摘要：
目的：微创寰枢椎手术可减少创伤和更快恢复。以前的研究集中在可行性和技术方面，但是缺乏全面的安全信息限制了其可用性和广泛使用。本研究提出以枕骨大神经与头下斜下缘的交点为参照点，界定手术安全性的可行性和范围。
方法：对10具新鲜尸体进行解剖，以将解剖参考点定义为枕大神经与下头斜肌下缘的交点。该研究旨在通过测量解剖参考点与轴的横孔之间的距离来分析微创寰枢融合手术的安全性范围。解剖参考点与后弓上边界的距离，解剖参考点和椎管之间的距离。使用Studentt检验比较测量值。
结果：枕大神经与下头斜肌下缘相交的点被定义为微创后路寰枢椎手术的解剖学标志。该解剖标记与轴的横孔之间的距离测量为9.32±2.04mm。此外,距后弓上缘的距离为21.29±1.93mm，与椎管的距离为11.53±2.18mm。这些测量结果可以帮助外科医生在微创后路寰枢椎手术中保护椎动脉和硬脑膜。
结论：枕大神经与下头斜肌下缘的交汇处是微创后路寰枢椎手术中安全可靠的解剖学标志。
