目的比较微波、液氮冷冻二种治疗方法对化脓性肉芽肿的治疗效果及术后瘢痕情况。方法将136例化脓性肉芽肿患者随机分为二组,分别用微波、液氮冷冻进行治疗,并观察每组疗效。结果微波组有效率为98.52%,一次性治愈率为92.64%;液氮冷冻组有效率为95.58%,一次性治愈率为77.94%。二组间有效率比较差异无统计学意义(校正χ2=0.26,P>0.05),二组间一次性治愈率比较差异有统计学意义(χ2=5.86,P<0.05),术后瘢痕形成情况差异无统计学意义(χ2=0.17,P>0.05)。结论微波、液氮冷冻二种治疗方法对化脓性肉芽肿疗效均良好,一次性治愈率微波组高于液氮冷冻组。两种治疗方法对组织损伤均较小,瘢痕形成较轻。
Objective To compare the therapeutic effects of microwave and liquid nitrogen freezing on pyogenic granuloma and postoperative scarring. Methods Thirty-six patients with pyogenic granuloma were randomly divided into two groups. The patients were treated with microwave and liquid nitrogen respectively, and the curative effect of each group was observed. Results The effective rate of microwave group was 98.52% and the one-time cure rate was 92.64%. The effective rate of liquid nitrogen freezing group was 95.58% and the one-time cure rate was 77.94%. There was no significant difference in the effective rate between the two groups (χ2 = 0.26, P> 0.05). There was significant difference in one-off cure rate between the two groups (χ2 = 5.86, P <0.05) The difference was not statistically significant (χ2 = 0.17, P> 0.05). Conclusion Microwave and liquid nitrogen freezing two kinds of treatment of pyogenic granuloma curative effect is good, one-time cure rate microwave group was higher than liquid nitrogen freezing group. The two treatments are less tissue damage, scar formation lighter.
