In order to evaluate the function of the inferior vestibular nerve (IVN), we used the caloric stimulation as the indicatior of the superior vestibular nerve (SVN) and galvanic body sway test (GBST) as total stimulation of the vestibular nerve.The materials of this project were chosen from the case of acoustic neuromas, because from our study, it is known that more than 80% of the cases of the tumors were originated from IVN.The results obtained were as follows.1. When the function of the SVN is good and the minimal laterality is present in GBST,this laterality is from the functional disturbances of the IVN.2. When the results of caloric stimulation and GBST as well show marked laterality, not only the function of SVN but IVN are also decreased.3. When the caloric response has no laterality and GBST has moderate laterality, this means the function of the IVN has to be decreased.These results will contribute to the evaluation of SVN and IVN in cases of Meniere's disease, sudden deafness with vertigo, vestibular neuronitis and so forth.

为了评估下前庭神经（IVN）的功能，我们将热量刺激用作上前庭神经（SVN）和电力体摇摆试验（GBST）的指示，作为前庭神经的总刺激。 IVN。获得的结果如下1。当SVN的功能良好并且GBST中存在最小的横向性时，该横向性来自IVN.2的功能干扰。当热量刺激和GBST的结果也显示出明显的横向性时，不仅SVN的功能，IVN的功能也降低了3。当热量响应没有侧向性并且GBST的侧向性中等时，这意味着必须降低IVN的功能。这些结果将有助于评估Meniere病的SVN和IVN，这会导致眩晕，前庭神经元炎的突然耳聋，等等。
