title: Head trauma and mid-frequency hearing loss.
abstract: Numerous reports in the literature associate head trauma with high-frequency hearing losses, often mimicking "4K notches" attributed to noise exposure. We have observed that some patients with a positive history for head trauma may show midfrequency notches in their audiometric configurations.
