Angular Relationship Between the Foramen Ovale and the Trigeminal Impression: Percutaneous Cannulation Trajectories for Trigeminal Neuralgia.

摘要: The debilitating pain of trigeminal neuralgia often necessitates neurosurgical intervention via percutaneous transovale cannulation. While most treatments are successful, severe adverse events resulting from failure to properly cannulate the foramen ovale (FO) have been reported. With regard specific targeting particular divisions (ie, V1, V2, V3, and combinations thereof), operative techniques described; however, these descriptions not included angulation data. This anatomic study analyzed angular relationship between centroid anteromedial- posterolateral-most aspects FO boundaries impression. is first detail impression in dry human skulls relative coronal plane. information may be used prevent miscannulation also target branches nerve for optimal results.
