# Hearing and Balance in Adult Patients with a History of Traumatic Brain Injury*

## TL;DR

This study shows that adults with a history of traumatic brain injury may experience hearing and balance issues, suggesting the need for specialist evaluation.

## Contribution

The study identifies a significant prevalence of hearing and balance disorders in TBI patients, emphasizing the importance of clinical assessment.

## Key findings

- 35.3% of patients failed the right ear hearing screening, and 38.2% failed the left ear.
- Balance tests revealed abnormal results in a portion of participants, indicating a risk of falling.
- The study highlights the need for otorhinolaryngological evaluation in TBI patients.

## Abstract

Traumatic brain injury (TBI) can result in peripheral or central injury, causing hearing loss.

To identify possible hearing and balance disorders in adult patients with a history of TBI.

Observational cross-sectional study conducted in a public hospital. The sample consisted of 34 individuals aged 18 to 60 years old who had suffered mild to severe TBI more than 6 months before. They underwent an otoscopy and a medical history survey, recording their clinical history, as well as their previous and current hearing and balance complaints. Next, their hearing was screened at 1,000, 2,000, and 4,000 Hz, and their balance was assessed using the Classic and Sharpened Romberg tests, as well as the Timed Up and Go test.

The present study assessed 34 patients, of whom 35.3% failed the right ear and 38.2% failed the left ear in the hearing screening, highlighting a statistically significant difference between the pre- and post-trauma results. Regarding balance, 3.1% had a positive result on the right and 3.1% positive on the left in the Classic Romberg test. The Sharpened test found a higher result of 9.4 positive on the left and front. The Timed Up and Go test results were normal for 75.0% and abnormal for 25% of the participants, revealing a risk of falling.

The present study demonstrated that adults after TBI may have hearing and balance complaints and changes, highlighting the importance of referral to an otorhinolaryngologist and subsequent clinical diagnosis in this population.
