分布于鼻粘膜的副交感神经在慢性肥厚性鼻炎的发病机理中有显著作用。本文用剌激翼管神经的方法研究了副交感神经的这种作用,在光镜和电镜下观察其对慢性肥厚性鼻炎的病人的鼻和上颌窦粘膜的影响。8例肥厚性鼻炎病人(3例男性,5例女性,年龄从16岁至52岁),用 Prades 法行翼管神经切除,暴露翼管神经。电刺激为0.8毫秒的方波脉冲和6Hz 固定频率,强度为5毫安,剌激时间分别为30、60、90、120或180秒;通常在刺激两次后,让病人休息5～10分钟。刺激前、后取受刺激翼管神经同侧的上颌窦和中鼻甲粘膜标本,做成切
Parasympathetic nerves distributed in the nasal mucosa have a significant role in the pathogenesis of chronic hypertrophic rhinitis. In this study, the effect of parasympathetic nerve was studied by stimulating the nerve of the pterygoid nerve and its effect on the nasal and maxillary sinus mucosa of patients with chronic hypertrophic rhinitis was observed under light and electron microscopy. 8 cases of hypertrophic rhinitis patients (3 males and 5 females, aged from 16 to 52 years old), with Prades method of pterygoid nerve excision, exposing the pterygoid nerve. The electrical stimulation was a square wave pulse of 0.8 milliseconds and a fixed frequency of 6 Hz with an intensity of 5 milliamperes and stimulation times of 30, 60, 90, 120 or 180 seconds, respectively; usually the patient was allowed to rest for 5 to 10 minutes after two stimuli . Before and after stimulation, the maxillary sinus and middle turbinate mucosa of the ipsilateral maxillary sinus were stimulated to stimulate
