国外1965年有人用低温冷冻治疗宫颈炎第一例取得成功后,近年来不断有更多的报道。我院自1975年11月开始应用液氮冷冻治疗宫颈糜烂、反复发作的颈管息肉、宫颈白斑及宫颈非典型增生共316例,获得比较满意的效果。一、冷冻治疗原理:利用液氮低温冷冻治疗造成细胞内冰晶形成,从而使细胞遭接机械损伤、脱水和皱缩、电解质毒性浓缩和pH值改变、细胞膜 In 1965 some people use cryogenic cryotherapy for the first case of cervicitis success, in recent years continue to have more reports. Our hospital from November 1975 began to apply liquid nitrogen cryotherapy for cervical erosion, recurrent cervical polyps, cervical leukoplakia and cervical dysplasia of a total of 316 cases, to obtain more satisfactory results. First, the cryogenic treatment principle: the use of liquid nitrogen cryogenic treatment resulting in intracellular ice crystals, so that the cells were subjected to mechanical damage, dehydration and shrinkage, electrolyte toxicity and pH changes, the membrane
