Mild traumatic brain injury (mTBI) and TBI in general have received greater attention in the past few years due in part to increased awareness of risks involved with sports-related brain injuries and with the return of veterans from Iraq and Afghanistan. Associated damage/dysfunction in the auditory system has been reported from tympanic membrane perforations (e.g., veterans with history of blast exposure) to complaints of inability to focus on and understand speech in noisy environments despite normal peripheral hearing sensitivity. The goals of this brief review are to provide an overview of the effects and underlying mechanisms of mTBI and to summarize the associated effects on the auditory system and how they may be reflected in audiometric tests.
