为了提高鼻咽癌脱落细胞学诊断的阳性率,我们设计使用负压吸引法,采集65例鼻咽癌病人鼻咽部脱落细胞进行检查,结果阳性率达92.3%。现将方法和结果介绍如下:(一)负压吸引法吸引管为一自行设计的内径为5毫米的金属空心管,管的顶端有一帽状金属小头(顶面直径为10毫米的蘑菇头),借螺旋固定于管上,小头顶面有6～7个直径为1.5毫
In order to improve the positive rate of exfoliative cytology diagnosis of nasopharyngeal carcinoma, we designed a negative pressure suction method to collect 65 cases of nasopharyngeal carcinoma patients nasopharyngeal exfoliated cells for inspection, the positive rate of 92.3%. The method and results will now be described as follows: (1) Vacuum suction method The suction tube is a self-designed metal hollow tube with an internal diameter of 5 mm. The top of the tube has a small metal cap (a mushroom head with a top diameter of 10 mm). ), fixed by a spiral on the pipe, the top surface of the small head has 6 to 7 diameters of 1.5 millimeters
