目的：：评价点阵 CO2激光联合液氮冷冻治疗鸡眼的临床疗效。方法：85例鸡眼患者随机分为两组：治疗组43例，给予点阵 CO2激光联合液氮冷冻治疗；对照组42例，单用液氮冷冻治疗，10日1次，共治疗3次。结果：治疗组与对照组痊愈率分别为90.70％和52.38％，有统计学意义(P<0.01)；治疗组与对照组复发率分别为2.56％和9.09％，无统计学意义(P>0.05)。结论：点阵 CO2激光联合液氮冷冻治疗鸡眼安全有效。%Objective: To assess the clinical efficacy of CO2 fractional laser combined with liquid nitrogen refrigeration in the treatment of clavus. Methods: Eighty-five patients with clavus were randomly divided into two groups: 43 patients in treatment group were treated with CO2 fractional laser combined with liquid nitrogen refrigeration and 42 patients in control group were treated with liquid nitrogen refrigeration alone. The treat-ment was one time every 10 days, for 3 times. Results: The cure rates in treatment group and control group were 90.9% and 52.3%, with a significant difference (P<0.01). The recurrent rates in treatment group and control group were 2.56% and 9.09%, with no significant difference (P>0.05). Conclusion: CO2 fractional laser combined with liquid nitrogen refrigeration is effective in the treatment of clavus.
