Evaluation of hearing loss and quality of life in patients with mild traumatic brain injury

This project will focus on auditory dysfunction following head injury, and findings will provide information about the pathophysiology of hearing loss after mild traumatic brain injury (TBI). To date, little has been described on this topic. We aim to assess auditory symptoms and their association with quality-of-life metrics in patients with mild TBI using patient-reported outcome measures. We further plan to analyze objective audiometric tests to understand the nature and severity of auditory dysfunction. Findings will be applied to clinical guidelines that address at-risk patients and the need for monitoring via audiometric testing. We anticipate findings will generate important discussion regarding an often-overlooked area of health effects following head injury.

Long-term goal: To better diagnose and treat patients with auditory dysfunction following head injury, thereby minimizing hearing loss, tinnitus, and hyperacusis. The study has implications for a broad range of individuals, including those with isolated head injuries as well as those with repetitive head injuries, such as athletes and military personnel.
