Overview

Brief Summary

In this study, we treated four patients with unilateral conductive or mixed hearing loss patients by using VSB. As a result, the hearing thresholds for all patients improved dramatically after VSB fitting from 67.2 dB HL to 25.6 dB HL. Monosyllable perception score in noise condition and sound localization score were also improved but did not show statistical significance.
