Introduction. It is important to ascertain whether vertigo is of the peripheral or the central origin, and whether other symptoms occur that may suggest a systemic disease or functional disorders.

Aim. The aim of the study was to evaluate the efficiency of the vestibular system in children with vertigo and balance disorders.

Material and methods. Study subjects comprised 14 girls and 16 boys at the age ranging from 5 to 17 years, with vertigo and balance disorders. ENG and VNG examinations, including assessment of spontaneous nystagmus, postural, oculomotor and caloric tests were performed in patients of the study group.

Results. Damage to the peripheral part of the balance system was diagnosed in 8 patients, the central type in 21, while one patient showed complete non-excitability of the labyrinth and bilateral congenital deafness. Static and dynamic trials were normal in 25 patients, 3 patients showed tendency to fall down backwards, and instability was detected in 2 patients. Normal hearing was noted in 22 children, one had bilateral conductive hearing loss. Six patients were diagnosed with unilateral deafness, and one with bilateral congenital deafness.

Conclusions. Most of vertigo occurring among children was not associated with damage to the peripheral part of the vestibular system. Both the VNG and ENG tests are very valuable in assessing the location of damage to the balance system. Due to the use of modern techniques, VNG test is a better diagnostic tool.
