目的探讨鼻腔扩容技术在治疗阻塞性睡眠呼吸暂停低通气综合征(OSAHS)中的意义。方法以鼻腔扩容技术理论为基础,对伴鼻腔结构异常的OSAHS患者施行鼻腔扩容手术,观察患者术后主客观症状改善情况。结果鼻腔扩容术可以有效减轻OSAHS患者的鼻堵和嗜睡症状,并提高了最低血氧饱和度。部分患者虽然手术前后呼吸暂停低通气指数(AHI)存在边缘性统计学差异,但术后AHI仍然较高,没有下降到正常水平。结论鼻腔扩容手术可以改善OSAHS患者鼻塞及白天嗜睡、睡眠打鼾等相关睡眠主观症状,并在一定程度上改善OSAHS患者的阻塞性睡眠呼吸暂停的严重程度,鼻腔扩容术提出了治疗OSAHS的新观念,但应适当选择手术适应证。 Objective To investigate the significance of nasal dilatation technique in the treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Based on the theory of nasal dilatation technique, nasal dilatation surgery was performed on OSAHS patients with nasal structure abnormalities. The objective and subjective symptoms were observed after operation. Results Nasal dilatation was effective in reducing nasal congestion and drowsiness in OSAHS patients and increased the lowest oxygen saturation. Although some patients had marginal statistical differences in apnea-hypopnea index (AHI) before and after surgery, the AHI remained high and did not decrease to normal level after operation. Conclusion Nasal dilatation surgery can improve subjective symptoms of nasal obstruction, daytime sleepiness and sleep snoring in OSAHS patients, and to some extent, improve the severity of obstructive sleep apnea in patients with OSAHS. Nasal dilatation technique proposed a new concept of OSAHS treatment, However, surgical indications should be properly selected.
