[摘要] 目的 探讨等离子低温射频消融(temperature-controlled radiofrequency ablation，RFA)治疗悬雍垂腭咽成形术(uvulopalatopharyngoplasty，UPPP)术后无效的阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome，OSAHS)的疗效。方法 选择19例UPPP术后无效的OSAHS患者接受RFA治疗。比较治疗前后呼吸暂停低通气指数(AHI)、最低血氧饱和度(LSaO2)、鼾声评级和Epworth嗜睡程度评分，评价治疗效果。结果 治疗总有效率68.4%，患者治疗8周后鼾声评级的降低较治疗前差异无显著性，Epworth嗜睡程度评分较治疗前降低非常明显(P<0.01)。治疗后6个月AHI较治疗前减低明显(P<0.05)，LSaO2较治疗前升高明显(P<0.05)。结论 对UPPP术后无效的OSAHS，RFA是一种有效的治疗方法。
