Hearing loss is a known symptom among people who suffer from traumatic brain injuries. Studies have shown that sensorineural hearing loss is the most common type of hearing loss resulting from traumatic brain injury. However, it is not well understood whether the auditory pathway is affected by traumatic brain injury. In this study, we examined the auditory radiation, using diffusion tensor imaging data and probabilistic tractography. Fifty-three veterans with traumatic brain injury and forty-four veterans without traumatic brain injury are compared. There was no significant difference in fractional anisotropy of the auditory radiation between those with and without traumatic brain injury. It is suggested that the auditory radiation is not impacted by traumatic brain injury, while sensorineural hearing loss is commonly found in individuals with traumatic brain injury.
