We studied vestibular evoked myogenic potentials in 6 patients after unilateral vestibular neurectomy and in 22 patients after unilateral vestibular neuritis and unilateral absent caloric responses. We found that the ipsilesional vestibular evoked potentials were abolished in every patient after unilateral vestibular neurectomy. In vestibular neuritis patients we found that the ipsilesional vestibular evoked potentials were absent in some but not in all cases. These findings confirm that the p13-n23 potential is of vestibular origin and also show that it is not of lateral canal origin.
我们研究了6例单侧前庭神经切除术后患者以及22例单侧前庭神经炎且单侧冷热试验反应消失患者的前庭诱发肌源性电位。我们发现，单侧前庭神经切除术后的每位患者患侧前庭诱发电位均消失。在前庭神经炎患者中，我们发现部分而非所有病例的患侧前庭诱发电位消失。这些发现证实p13 - n23电位起源于前庭，也表明它并非起源于水平半规管。
