Abstract

Aim

The aim of this study is to detect saccular dysfunction tests using vestibular evoked myogenic potentials (VEMPs) in dizzy patients with normal videonystagmography (VNG) findings.

Patients and methods

Thirty patients complaining of dizziness with normal VNG findings were studied. They were subjected to full assessment of history, basic audiological evaluation, VNG, and VEMPs. VEMPs were evaluated in both ears of all cases through absolute latencies of p13 and n23.

Results

VEMPs showed abnormalities in 19 patients (66.3%). Ten patients (33.3%) showed unilateral absent, six patients (20%) showed bilateral absent, and three patients (20%) showed shifted latencies.

Conclusion

VEMP appears to be a valuable tool in the detection of initial saccular abnormalities initially in dizzy patients with normal VNG findings.
