Patient-reported auditory handicap measures following mild traumatic brain injury

Abstract

Objectives/Hypothesis: Few studies have specifically addressed auditory complaints in patients with nonblast mild traumatic brain injury (mTBI). Herein, we aimed to investigate auditory symptoms in patients following mTBI using patient-reported outcome measures. Study Design: Retrospective analysis of prospectively collected data in a tertiary-care hospital. Methods: The patients included those with mTBI (cases) and those without mTBI (controls). Individuals (≥18 years old) with and without mTBI were screened. Exclusion criteria included history of otologic disorders, blast injury, or occupational noise exposure. Primary outcomes included the Hearing Handicap Inventory for Adults (HHIA), Tinnitus Handicap Inventory (THI), and Hyperacusis Questionnaire (HQ). Secondary outcomes included subjective auditory complaints. Results: From September 2017 to September 2018, 52 patients with mTBI and 55 controls met inclusion and exclusion criteria. The mean time between mTBI and survey intake was 70.6 months. The mean age and gender were 51.5 years old and 73% female in the mTBI group, and 46.1 years old and 56.3% female in the control group (P =.112 and P =.105, respectively). Patients with mTBI reported hyperacusis (67.3% of all mTBI patients), hearing loss (61.5%), and tinnitus (61.5%), compared to 8.3%, 12.7%, and 16.4%, respectively, for control subjects (P
