Abstract

BACKGROUND: Depending on the type of collision, car occupants who are involved in traffic accidents are often exposed to the unexpected effects on the cervical spine of traumatic stimuli from different directions. In a rear-end collision or a frontal collision of the car it is most likely that there is an effect of linear acceleration and a lateral or side impact acceleration of axial rotation on the cervical spine. The neuro-otological manifestations of whiplash injuries that can occur in response to various trauma mechanisms have not yet been sufficiently investigated. Method: Data from 64 patients who suffered a whiplash injury were selected for analysis. In 32 patients the trauma mechanism was a sudden action on the cervical spine from a linear impulse caused by a head-on collision of cars or rear-end collision. In the other 32 patients the trauma mechanism was a sudden action of an axial neck rotation at a side impact collision or a cross collision. The study compared the results of neuro-otological findings between the two patient groups. RESULTS: A comparison of the neuro-otological examination data of 64 patients revealed that there were 32 patients who had a sudden injury mechanism of cervical axial rotation, the prevalence of central vestibular and sensory impairments, such as pathological central nystagmus disinhibition, pathological changes in the auditory brainstem evoked potentials (ABEP), the auditory evoked cortical potentials (ALEP) and visual evoked potentials (VEP). In the second group of patients where the injury mechanism consisted of an unexpected linear momentum, peripheral vestibular and sensory disorders were predominant. CONCLUSION: The observed differences in neuro-otological manifestations of whiplash trauma, which occur depending on the trauma mechanism, can be used for differential diagnostic purposes. The whiplash injuries of the cervical spine induced by an axial rotation acceleration showed a prevalence of central vestibular and sensory disturbances, while the whiplash injuries of the cervical spine induced by a linear acceleration showed a prevalence of peripheral vestibular, sensory and vestibulospinal disorders. Our data thus show in the first group of patients a prevalence of retrocochlear, supratentorial and subcortical lesions of the auditory tract, and brain lesions of the optic tract in the occipital pole and in the visual cortex.
