Although abducens nerve palsy is an established sequela of head trauma - given the prolonged intracranial course of the nerve - bilateral injury is rare. Here, we present two cases of bilateral traumatic abducens nerve avulsion, in the absence of regional fractures, one of which presented two months following the initial trauma. Additionally, we review the current literature on bilateral abducens nerve palsy secondary to trauma, discussing the anatomy of the nerve's course and potential mechanisms of injury.
虽然外展神经麻痹是头部创伤的既定后遗症——鉴于该神经的颅内行程较长——双侧损伤很少见。在此,我们报告两例双侧创伤性外展神经撕脱病例,均无局部骨折,其中一例在初次创伤后两个月出现。此外,我们回顾了目前关于创伤性双侧外展神经麻痹的文献,讨论了神经行程的解剖结构和潜在的损伤机制。
