Injury to cranial nerves is a common sequela of blunt head trauma. The olfactory, facial, and audiovestibular nerves are damaged most often, followed by the optic and ocular motor nerves. The trigeminal and lower cranial nerves are rarely involved. Chances of recovery are greatest for the facial nerve, intermediate for the ocular motor nerves, and least likely for the olfactory, optic, and audiovestibular nerves. Treatment is usually symptomatic, although steroids or surgical decompression of the optic and facial nerves can lead to dramatic results in selected patients.
颅神经损伤是钝性头部外伤常见的后遗症。嗅神经、面神经和听前庭神经最常受损，其次是视神经和动眼神经。三叉神经和低位颅神经很少受累。面神经恢复的可能性最大，动眼神经次之，而嗅神经、视神经和听前庭神经恢复的可能性最小。治疗通常是对症治疗，尽管在部分患者中，使用类固醇或对视神经和面神经进行手术减压可产生显著效果。
