ABSTRACT
Thirty-six patients with tinnitus but normal hearing [as proved by pure-tone audiometry and immittancemetry] were investigated to determine the values of the blood flow velocities and the hemodynamic changes in the extra-cranial vertebral arteries [VAS]- by color flow Doppler ultrasonography-for the detection of a possible cause of tinnitus in these cases. Further investigations were done to correlate their findings with that of vertebral arteries Doppler blood flow [VABF] and to study the accuracy and reliability of this recent tool of investigation. Abnormal Doppler findings could be detected in 15 cases. A significantly slow VABF was reported in tinnitus group compared with the control group
