To prove the influence of the vertebral nerve on hearing in rabbits, the vertebral artery, together with its sympathetic plexus (n. vertebralis Frank), was unilaterally cut at the height of the first vertebral body, the atlas. Both preoperatively and several times after dissection, auditory and vestibular functions were investigated using BERA and electronystagmography. The hearing threshold was not influenced, neither in the first days after the operation nor as much as six months later. The latencies between wave I and V did not change. Similar results were to be found for the vestibular system. There was no imbalance clinically and it was not possible to detect any electronystagmographic difference between the two vestibular organs. These results indicate, that there is still no experimental proof of hearing loss, as a result of disturbance of the sympathetic vertebral nerve.
为了证明椎动脉神经对家兔听力的影响，在第一椎体（寰椎）高度处单侧切断椎动脉及其交感神经丛（Frank椎动脉神经）。在术前以及解剖后的几个时间点，使用脑干听觉诱发电位（BERA）和眼震电图对听觉和前庭功能进行了研究。术后第一天以及术后长达六个月，听力阈值均未受到影响。I波和V波之间的潜伏期没有变化。前庭系统也得到了类似的结果。临床上没有出现失衡情况，并且无法检测到两个前庭器官之间存在任何眼震电图差异。这些结果表明，目前仍没有实验证据证明交感椎动脉神经紊乱会导致听力损失。
