著者对鼻窦的几项主要病理生理作用进行研究: 1.上颌窦的通畅度:自然孔堵塞是发生鼻窦炎的重要病理生理因素,通过测量向上颌窦注水冲洗时的阻力,可以了解上颌窦堵塞的程度。用两个导管插入上颌窦内,一个用于吹入气体,另一个测定压力,所使用的导管有不同型号,通过对不同型号导管的造模观察,即测出与导管型号相似的患者自然孔的机能,经观察压力之增加与上颌窦体积无关。上颌窦自然孔之大小并不恒定,随体位变化而改变,当人体从坐位慢慢躺下时,自然孔逐渐缩小,从半躺位30度至水平位,对自然孔的影响最大,尤其急性鼻窦炎发作时尤
The author of the sinuses of several major pathophysiological effects: 1. Maxillary sinus patency: natural hole occlusion is an important pathophysiology of sinusitis, by measuring the maxillary sinus irrigation water resistance, you can understand the maxillary sinus obstruction Degree. Two catheters were inserted into the maxillary sinus, one for gas insufflation, and the other for pressure measurement. The catheters used were of different types. By modeling the different types of catheters, the natural orifice of the patient The function of the maxillary sinus has been found to be independent of the volume of the maxillary sinus after the observed increase in pressure. The size of natural hole in maxillary sinus is not constant and varies with body position. When the human body slowly recovers from the sitting position, the natural hole shrinks gradually. From 30 ° to 30 °, the effect on the natural hole is greatest, especially acute Sinusitis attack especially
