[Value of cortical acoustic evoked potentials in sensorineural hypoacusis of vascular genesis].

Sixty patients 19 to 43 years of age (28 females and 22 males) with neurosensory hypoacusis (NH) of vascular genesis were examined using long-latent acoustic evoked potentials. The patients were divided into three groups. Group 1 consisted of 20 NH patients with initial hypertension, frequent headache, vertigo, sleeplessness, irritability but no complaints of hearing problems.
