Two cases of vestibular neuronitis in childhood *
Acute unilateral and/or bilateral vestibular paralysis without any cochlear symptoms, is known as vestibular neuronitis. In 1952, Dix & Hallpike were the first to define the disease as a clinical entity on the basis of 100 cases. Since then many clinical and basic studies have been reported. In 1987, the diagnostic criteria of vestibular neuronitis were determined by the Standardization Committee of the Japan Socicty of Equilibrium Research and have been applied in Japan. The peak of age distribution for this condition is between 30-50 years, so only a few specialists have dealt with vestibular neuronitis in childhood. Two eases of vestibular neuronitis in childhood were reported. One patient had had a preceding episode of upper respiratory tract infection. Spontaneous horizontal-rotary nystagmus to the intact side and caloric CP of the lesioned side were observed in both cases during the first medical examinations. In the two cases the sensation of vertigo disappeared and disappearance of nystagmus was observed early in the clinical course.
