根据上颌窦口阻力的高低,可预测窦粘膜,尤其是窦口粘膜病变的程度,因而可为临床选用治疗方法提供客观依据。为此,我们自制了一种简易的上颌窦口阻力测定装置。现将该装置的制作和使用方法介绍如下。一、测压装置用两个容积2500ml的储液瓶,盛满液体,一为测压瓶,瓶口接有刻度的玻璃管;一为冲洗瓶,该瓶的一玻璃管连接上颌窦穿刺针,另用
According to the level of maxillary ostium resistance, can predict the degree of sinus mucosa, especially ostium mucosal lesions, which can provide an objective basis for clinical choice of treatment. To this end, we made a simple homemade maxillary ostium resistance measurement device. The device is now the production and use of methods are described below. First, the pressure measuring device with two volumes of 2500ml liquid storage bottle, filled with liquid, a pressure measuring bottle, bottle mouth connected to the graduated glass tube; a flushing bottle, a glass tube connected to the maxillary sinus puncture needle , Another use
