  • Abstract
  • Look Inside

 Section of the chorda tympani nerve performed in 4 cases for the treatment of Ménière's disease with prognosis of the procedure and a few other questionable points are discussed. The patients were women, aged 24 to 41, on whom the operation was performed from 2 to 5 years ago. The treatment was definitely effective in all cases in allaying the dizziness. However, there was no effect upon the tests of hearing, tinnitus and of caloric nystagmus.

 Subjective sense of taste showed recovery in 3 cases out of the 4, in 3 to 6 months after the operation and by electrogustometry 2 cases out of this group were completely recovered. But there seemed to be no relation between the recovery of the taste with that of the dizziness.

 The progress of the spontaneous nystagmus was examined during preoperative, during operation and postoperatively, but there seemed to no effect due to the section of the chorda tympani nerve. Consequently, it seemed that the effect ofthe nerve section was unrelated to the recovery of dizziness which implies that there is no relation between the dizziness and the vestibular system. The authors believe that the dizzinessmay the result of psychological disturbance and the relief of the tension of the autonomic nervous system appeared to be more appropriate.
