摘要
目的：观察伴其他颅神经症状的面神经炎患者治疗前后的脑干听觉诱发电位（BAEP）表现.方法：选择50例面神经炎伴其他颅神经症状的患者进行BAEP检测,并进行治疗前后对比.结果：与治疗前相比,治疗后Ⅱ-Ⅲ、Ⅲ-Ⅴ、Ⅰ-Ⅴ波IPL明显缩短（P〈0.01）,其中有一个以上的IPL缩短者42例占84%;Ⅰ、Ⅲ、Ⅴ波PL有一个以上缩短或治疗前BAEP波形消失而于治疗后出现者37例占74%;Ⅴ波波幅增高并且Ⅴ/Ⅰ IPL比大于0.5或双侧Ⅴ波侧间潜伏期差（IDL）小于0.3 ms,Ⅲ-Ⅴ波IPL小于Ⅰ-Ⅲ波IPL的35例占70%.结论：面神经炎不仅累及茎乳孔内面神经,还可累及脑干和其他颅神经.BAEP可以客观地反映面神经炎患者听觉系统和脑干功能,因此可以用于对该类患者进行疗效观察.
Objective：To explore the clinical applied value of brain stem auditoryk evoed potential （BAEP）in facial neuritis patients combined with damage of other cranial nerves. Methods： Fifty facial neuritis patients combined with damage of other cranial nerves were selected to get BAEP information; the results before and after treatment were analyzed. Results：The inter-peak latencies （IPL） of I -- III, II -- V , I - V were significantly shorten（P〈0.01）after treatment of the. More than one IPL shortened IPL took up 84%. 74% cases had prolonged potential latencies （PL） of Wave I , III and V with more than one shortened or disappeared waveform. In 69 % cases with amplitude of wave V increased and ratio of V/I more than0.5 or ILD of bilateral Wave V was less than 0.3 ms, IPL of III-V shorter than that of I -III Conclusion：Facial neuritis involves not only medial surface nerves of foramen stylomastoideum but also brainstem and/or other cranial nerves . BAEP can objectively reflect the function of auditory system and brain stem, and can be used to follow-up with patients with facial neuritis.
