ABSTRACT
Spontaneous and experimental vestibular activity in 84 patients after total resection of neurinomas of the acoustic nerve is analysed. In the immediate postoperative period the frequency of marked manifestations of spontaneous vestibular activity reduced sharply, but spontaneous nystagmus persisted in 97.5% of patients. In some patients spontaneous nystagmus to the side from which the tumor had been removed become more conspicuous. In the remote postoperative period spontaneous nystagmus was unilateral in 45.5% of patients, bilateral in 40.3%, and not recorded at all in 14.2% of patients. In the early postoperative period vestibular hyperreflexia was recorded in 93.7% of cases, in the remote period it was found in 76.6% of cases. Data obtained by comparing the results of caloric tests with cold and hot water in these patients are also analysed.

The study was conducted in 3 patients following the application of intracranial facial nerve anastomoses, in 25 patients with the facial nerve anastomosed with the accessory nerve, and in 17 patients with facial-hypoglossal nerve anastomoses. Apart from the clinical observations of the facial muscle contractions, the comparative evaluation of the plastic operations was conducted with the aid of electromyography, electrogustometry and salivary glands secretion studies. The authors concluded that the intracranial anastomosis results in better restoration of the motor function of the facial muscles, the gustation being also partially restored on the side on the intervention. Among the anastomoses of the VII nerve with the XII and XI that with the XII is preferred.
