【摘要】： 经口咽入路(transoraltranspharyn-geal approach,TOA)手术是处理颅脊交界区(craniovertebral junction,CVJ)腹侧病变的传统术式之一,手术入路层次简单,无须牵拉重要血管和神经,可直接解除脊髓腹侧受压等优点。但该区域的解剖数据还不全面。为了给该手术入路提供准确的解剖学依据,我们较全面地测量相关解剖数据。本研究通过对颅的水平切面10个标本、头颈部尸体标本20个,其中10个行正中矢状切面进行测量,得出了切牙孔下缘至后鼻棘、切牙孔下缘至咽结节、切牙孔下缘至枕骨大孔前端以及颅底内面斜坡高、寰椎前弓高、枢椎全高(含齿突) ,双侧椎动脉外径。结论:对于颅颈交界区腹侧中线病变的切除,距离短,解剖层次简单,可在直视下进行手术。即使是处理硬脑膜内的病变,也可避免对延髓、颈脊髓、后几对脑神经和椎动脉等结构的牵拉,因此只要适应症选择恰当,此入路对颅颈交界区的病变切除是较好的选择。
[Abstract]:Transoraltranspharyn-geal approach via oropharyngeal approach. Toa is one of the traditional procedures for the treatment of cranial craniocerebral junction (Craniocranium junctional junction CVJ), and the surgical approach is simple. It can relieve ventral compression of spinal cord directly without pulling important vessels and nerves. But the anatomical data in this area are not comprehensive. In order to provide accurate anatomical basis for the surgical approach. We measured the related anatomical data comprehensively. In this study, we measured 10 specimens of cranial horizontal section and 20 cadavers of head and neck, of which 10 were measured on the median sagittal plane. From the lower margin of incisor to the posterior nasal spine, from the lower margin of incisor to the pharyngeal nodule, from the lower margin of incisor to the anterior part of foramen magnum occipital, and from the inner slope of skull base, the anterior arch of atlas and the total height of axis (including odontoid process) were obtained. Conclusion: the distance is short, the anatomical level is simple, and the operation can be carried out under the direct vision for the lesion of the ventral midline of the craniocervical junction. Even the treatment of the lesions in the dura mater can avoid the oblongation of medulla oblongata. The cervical spinal cord, the posterior few pairs of cranial nerve and vertebral artery, etc., so long as the indication is appropriate, this approach is a good choice for the craniocervical junction lesion resection.
