鼻腔为呼吸道的起点,其前后孔的口径大小及相互比例,对鼻腔和整个呼吸道的生理、病理都有很大影响。而国内的文献资料甚少,为此我们测量了54例正常人的鼻阈,20具尸体的鼻后孔和26个头颅骨的梨状孔和鼻后孔,现分述如下: 方法:先取所测部位之腊型,然后切取它的断面,用卡尺测量高、横,再按断 Nasal cavity as the starting point of the respiratory tract, the size of the aperture before and after the hole and the proportion of each other on the nasal cavity and the respiratory tract have a great impact on the physiology and pathology. However, there is little literature in our country. For this reason, we measured nasal threshold of 54 normal people, posterior nasal orifice of 20 corpses and piriform holes and nasal posterior orifice of 26 skull. The methods are as follows: Part of the wax-type test, and then cut its cross-section, using calipers to measure high and low, then press the broken
