头晕和眩晕是轻微头部外伤后的常见症状。尽管许多患者的这些症状会在几周内消失，但在某些患者中，症状可能会持续更长时间，并妨碍重返工作岗位和充分发挥功能的能力。持续性或反复性头晕的原因可能包括良性阵发性位置性眩晕、所谓的迷路脑震荡、单侧前庭神经损伤或椭圆囊或球囊损伤、外淋巴瘘或较少见的外伤性内淋巴积水。头部外伤后的一些头晕是由于非迷路原因引起的，可能与结构或微观结构中枢神经系统损伤有关，或者与偏头痛、广泛性焦虑以及与患者自我感知、易感心理状态以及环境和压力相关因素相关的问题之间更复杂的相互作用有关。在本文中，作者回顾了脑震荡后头晕的内耳原因，以及目前对无法确定外周前庭原因的慢性脑震荡后头晕的理解。
Dizziness and vertigo are common symptoms following minor head trauma. Although these symptoms resolve within a few weeks in many patients, in some the symptoms may last much longer and impede ability to return to work and full functioning. Causes of persisting or recurrent dizziness may include benign paroxysmal positional vertigo, so-called labyrinthine concussion, unilateral vestibular nerve injury or damage to the utricle or saccule, perilymphatic fistula, or less commonly traumatic endolymphatic hydrops. Some dizziness after head trauma is due to nonlabyrinthine causes that may be related to structural or microstructural central nervous system injury or to more complicated interactions between migraine, generalized anxiety, and issues related to patients self-perception, predisposing psychological states, and environmental and stress-related factors. In this article, the authors review both the inner ear causes of dizziness after concussion and also the current understanding of chronic postconcussive dizziness when no peripheral vestibular cause can be identified.
