【摘要】 目的 探讨手术治疗鼻气道狭窄对阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome，OSAHS)患者的疗效。 方法 2008年2月-2010年2月，对300例OSAHS患者行鼻内镜鼻腔手术治疗，比较患者手术前后打鼾程度、嗜睡程度和鼾声评分。 结果 手术治疗鼻气道狭窄后患者嗜睡评分及鼾声评分平均值均小于术前，差异有统计学意义(Plt;0.05)，手术有效率88.67%，手术并发症发生率0.67%，为鼻中隔穿孔、鼻腔粘连。 结论 手术治疗鼻气道狭窄是治疗因鼻气道狭窄所致OSAHS的一种有效方法。【Abstract】 Objective To explore the therapeutic effect of the surgery of narrow nasal cavity on the obstructive sleep apnea hypopnea syndrome (OSAHS). Methods A total of 300 patients with OSAHS from February 2008 to February 2010 underwent the surgery of narrow nasal cavity and the pre- and post-operative Epworth sleepiness scale and snore scale were analyzed. Results After the surgery of narrow nasal cavity, snore degree, somnolence scale and snore scale decreased compared with those before the operation (Plt;0.05). The effective rate of the surgery was 88.67% and the rate of operative complication was 0.67%. Conclusion The surgery of narrow nasal cavity is effective for the patients with OSAHS caused by narrow nasal cauity.
