The association between positional vertebral and basilar artery flow lesion and prevalence of vertigo in patients with cervical spondylosis.

Objective: The aim of our investigations was to characterize the relationship between basilar artery (BA) flow velocity in patients with cervical spondylosis and age, grade of radiological changes, prevalence of vertigo, and decreased blood flow velocity through vertebral arteries (VA) after head rotation.

Study Design And Setting: A prospective, controlled study in academic neurotology was conducted. We examined 80 patients with radiological evidence of cervical spondylosis.
