The sensation of vertigo or dizziness shows individual differences in patients with inner ear or vestibular nerve damage. This study was designed to correlate the sensation of vertigo or dizziness with the severity of inner ear or vestibular nerve lesions. 1. Unilateral inner ear lesions Three months after the initial medical examination, patients no longer complained of vertigo or dizziness, and in 86%, the inner ear had recovered normal function. When the caloric response on the side of the lesion had recovered over 50% of normal function, 90% of the patients no longer complained of vertigo or dizziness. 2. Unilateral vestibular nerve lesions Three months after the initial medical examination, 90% of the patients no longer complained of vertigo or dizziness. When the caloric response on the side of the lesion had recovered over 30% of normal function, none of the patients complained of vertigo or dizziness.
