冷冻疗法是近二十年发展起来的新技术,在临床上广泛应用。我科自1981年以来,对口腔颌面部血管瘤、疣、痣、色素沉着、角化病、瘢痕疙瘩等共2,718例病人进行液氮冷冻治疗,从最后的疗效看,都是比较满意的(有另文总结)。但由于颜面部组织疏松、血运丰富,术后水肿十分明显,甚至出现大泡和血泡,个别病例还有继发感染的情况。为了避免这些缺陷,我们采取了各种措施,如冷冻前常规消毒、冷冻后创面涂龙胆紫,全身用抗炎药及维生素C等,都收到了一定的效果、最后我们试用了新鲜鸡卵膜覆盖冷冻后创面,临床观察收到了好效果。病例选择:我们选择颌面部血管瘤病人共34例,其中毛细血管型血管瘤19例、海绵状血管瘤15 Cryotherapy is a new technology developed in the past two decades, widely used in clinical practice. Our department since 1981, on oral and maxillofacial hemangioma, warts, moles, pigmentation, keratosis, keloids and a total of 2,718 patients with liquid nitrogen cryotherapy, the final effect from the point of view, are more satisfied (There is another summary). However, due to loose facial tissue, rich blood supply, postoperative edema is very obvious, and even bubble and bubble, in some cases there are secondary infections. In order to avoid these defects, we have taken a variety of measures, such as routine disinfection before freezing, after the wound gel coated gentian violet, systemic anti-inflammatory drugs and vitamin C, have received some results, and finally we tried a fresh egg Membrane coverage frozen wounds, clinical observation received good results. Case Selection: We selected a total of 34 patients with maxillofacial hemangiomas, including 19 capillary angiomas, cavernous hemangiomas 15
