临床资料45例中男25人,女20人;最大年龄70岁,最小年龄15岁;病程短者3个月,最长者达28年.高负压操作方法:将临床常用的普通型吸引器与鼓气耳镜侧孔相连接.吸引时根据外耳道大小更换合适之耳镜头,使外耳道口与耳镜密合.患者取坐位或卧位,把耳镜密接于外耳道口,起动吸引器,通过耳镜在直视下观察吸引情况,吸至基本上无脓汁,并吸出肉芽组织及胆脂瘤样脱屑,每次吸引操作时负压一定要达到80kPa左右.如脓汁较多而粘稠负压最高可达93.3kPa.如果负压低于40.0kPa则疗效欠佳.
Clinical data of 45 cases, 25 males and 20 females, the maximum age of 70 years, the youngest age of 15 years; the short duration of 3 months, the longest up to 28 years. High negative pressure method of operation: the clinical common type of attraction The device is connected with the side hole of the otoscope and is suitable for changing the size of the external auditory canal so as to make the external auditory canal mouth and the otoscope close together.The patient takes the sitting position or the supine position and closely attaches the otoscope to the external auditory canal, Through the otoscope under direct vision to observe the attraction, sucked to basically no pus, and aspiration of granulation tissue and cholesteatoma desquamation, each suction operation when the negative pressure must reach about 80kPa. If more pus and Viscous negative pressure up to 93.3kPa. Negative pressure below 40.0kPa ineffective.
