对连续30例急性单侧外周性面瘫病人观察三叉神经功能。于起病后5周内进行电生理学检查,三叉诱发电位(TEP)检查发现47％的病人有三叉神经功能障碍,60％的病人电刺激引起瞬目反射(BR)结果表明有三叉神经病变,其中6例有脑干受累表现,2例TEP不正常,BR正常。25例所作ABR检查者中7例异常,只有3例TEP、BR和ABR均异常。作者从而认
Trigeminal nerve function was observed in 30 consecutive patients with acute unilateral peripheral facial paralysis. Electrophysiological examination was performed within 5 weeks after the onset of the disease. Tricuspid evoked potentials (TEP) showed that 47% of the patients had trigeminal dysfunction and 60% of patients had blinking reflex (BR). The results showed that there were trigeminal neuropathy, Six cases had brainstem involvement, two cases had abnormal TEP, and BR was normal. Of the 25 patients who underwent ABR, 7 were abnormal and only 3 had abnormal TEP, BR, and ABR. The authors thus recognize
