両側三叉神経知覚システムの調査

抄録

Ⅰ．Purpose

　Anatomic studies indicate a strict midline separation in the standard cutaneous innervation maps in the peripheral trigeminal system^1）. Similarly, in the central nervous system, the established orofacial pain pathway suggests no direct anatomic connection between the bilateral trigeminal nerves^2）. However, a previous study demonstrated pain attenuation after botulinum neurotoxin type A injection contralateral to the nerve injury, suggesting an association between the trigeminal nerves^3）. Therefore, this study aims to investigate the potential link between the right and left trigeminal nerves.
