Regional vascular relationships to the foramen ovale: an anatomical study with application to approaches to the external skull base with an emphasis on transcutaneous procedures for the treatment of trigeminal neuralgia.

摘要: Object The foramen ovale and its neighboring vascular structures may be seen via external approaches to the skull base. More commonly, however, transcutaneous are performed. Although complications with this latter technique uncommon, studies of distances surrounding extracranial lacking in literature. present study aimed elucidate such anatomical relationships. Methods Twenty adult cadavers (40 sides) underwent dissection region at Measurements between surface were made. Results From nearest aspect undersurface ovale, authors found that mean middle meningeal artery, maxillary superior bulb internal jugular vein, carotid artery entrance exit from canal 3, 19, 20, 9, 12 mm, respectivel...
