Audioscan testing in patients with King-Kopetzky syndrome.

In this study, the Audioscan test has been used to detect early signs of hearing abnormalities in 80 patients with King-Kopetzky syndrome. A significantly higher prevalence of Audioscan notches between 500 and 3,000 Hz was found for each age band and gender in patients with King-Kopetzky syndrome than in control subjects. This indicates that Audioscan notches between 500 and 3,000 Hz may represent a fine hearing deficit as an indicator of mild auditory dysfunction in patients with King-Kopetzky syndrome. However, there was no significant difference in the percentage of notches in the 3,001-8,000 Hz frequency band between the King-Kopetzky syndrome and control groups.
