从1974年6月起,我们应用液氮低温治疗口腔粘膜白斑近100余例。且曾先后在“新医学”、“人民军医”杂志上作过报导,本文拟报告液氮冷冻口腔白斑4—6年患者随访结果,以了解冷冻对口腔白斑的治疗价值。一、临床资料1974年6月至1980年8月对口腔白斑应用液氮冷冻治疗103例,随访率为73.7%(76/103)。本组随访期最长为六年,最短为四年。 From June 1974 onwards, we use liquid nitrogen hypothermia treatment of oral mucosa nearly 100 cases of white spots. And has in the “New Medicine”, “People’s Military Medical” magazine has reported that this paper is intended to report the liquid nitrogen frozen oral leukoplakia patients 4-6 years follow-up results to understand the treatment of oral leukoplakia value. First, the clinical data of June 1974 to August 1980 applied to oral leukoplakia cryogenic treatment of 103 cases, the follow-up rate was 73.7% (76/103). The longest follow-up period of this group is six years, the shortest of four years.
