In 2 patients with delayed endolymphatic hydrops, labyrinthectomy was carried out because they had severe vertiginous attacks in spite of continuous conservartive drug therapy. The process of central compensation in vestibular asymmetry after surgery was evaluated by observation of nystagmus and movements of the center of gravity during standing in each patients. Both patients never experienced recurrence of vertigo and their gaze nystagmus disappear early after operation but nystagmus under the condition without visual fixation were remained for a long time. The pattern on statokinesigrams showed the lateral sway type in the early stage and later the central type with small magnitude in each. Vestibular rehabilitation was attempted in both patients. The patient who started exercises early and continued the exercises for a relatively long term, was successfully treated. However, it failed to accelerate the compensation in the other patient whose exercises late and continued the exercises for short duration.
