Labyrinthotomy was performed on 2 cases of end-stage of Menieres disease. Postoperative vesti- bular inbalance and its compensation were exami- ned for about 200 days after the operation. The postoperative spontaneous nystagmus were recorded. Goniometer test and Fukudas eye fol- ded vertical writing test were examined. Results obtained were as follows : 1. Direction and continuance of the nystagmus Duing 2 days after the operation the nystag- nnus was directed towards the unoperated side. Three to 10 days after the opertion the direfion of the nystagmus changed towards the operated side, and after that the nystagmus was directed to the operated side again. 2. Deviation of writing axis in the vertical writing test with eyes folded was directed to the same direction of the slow phase of the nystagmus and continued in parallel with the nystagmus. 3. The influence of labyrinthotomy upon gonio- metric inbalance was more manifest than upon the nystagmus.
