Objectives: The present study was designed to determine the value of the blood flow velocity and hemodynamic changes in the extracranial vertebral arteries in adults with vertigo by using color flow Doppler ultrasonography. Material and Methods: Ninety-six adult patients with vertigo without definite otogenic causes (clinically and audiologically normal) were investigated by color flow Doppler ultrasonography. Electronystagmography was done to correlate its findings with those of vertebral arteries Doppler blood flow (VABF).
