Objective: To explore the CO2 laser new treatment and effective for com. Methods: 120 patients had been treated by the CO2 laser direct vaporizing in traditional method. 104 patients had been treated in new method, that firstly the pathologic tissue of the corn was cleared away by surgical scissors, lastly the remnant tissue was vaporized by the CO2 laser. Results: The effective rate of traditional method group was 94.1％ (113/120), the new method group was 97.1％ (101/104). By X2 tests, the difference was no significant (X2=1.136, P＞0.05). Wound diameter of the traditional method group was (1.32±0.68) cm, the healing time of the traditional method group was (6.96±0.86) days; wound diameter of the new method group was (0.65±0.35) cm, the healig time of the new method group was (2.77±0.27) days. By analysis of t tests, wound diameter and the healing time between the two groups both had significant difference (t=2.03, P＜0.05; t=3.42, P＜0.05). Conclusion: The new method group is better than the traditional method group. The new method of CO2 laser treatment for com is a simple and practical technique with less side effect.%目的:探讨CO2激光治疗鸡眼的新治疗方法及其效果.方法:120例患者用CO2激光传统方法直接气化治疗(旧疗法组);104例患者用新方法治疗(新疗法组),即先用手术剪清除鸡眼病变组织,最后激光气化残余部分.结果:旧疗法治愈88例,好转25例,有效率为94.1%(113/120);新疗法治愈85例,好转16例,有效率为97.1%(101/104),经χ2检验,两组有效率比较无显著性差异(χ2=1.136,P>0.05).旧疗法伤口直径(1.32±0.68)cm,好转时间(6.96±0.86)d;新疗法伤口直径(0.65±0.35)cm,好转时间(2.77±0.27)d.两组伤口直径经t检验,有显著性差异(t=2.03,P<0.05);两组术后伤口好转时间经t检验,亦有显著性差异(t=3.42,P<0.05).结论:新方法治疗组优于传统方法治疗组.CO2激光治疗鸡眼新方法是一种治疗鸡眼简单实用、副作用少的方法.
