目的:探讨鼻塞对阻塞性睡眠呼吸暂停综合征(OSAS)发病的影响。方法:对18例诊断为鼻塞和腭咽平面阻塞的OSAS患者,单纯行鼻腔手术改善通气,6个月后复诊。结果:12例睡眠阻塞症状缓解,其中4例效果明显;6例无效。睡眠呼吸紊乱指数(AHI)由术前的29.9±2.1降至22.8±2.7;夜间最低血氧饱和度由(75.0±2.9)％升至(83.4±2.3)％;而体重指数无明显差异。无效组与有效组的术前AHI值差异有显著性意义。结论:鼻塞是OSAS的重要致病因素,早期治疗解除鼻塞是预防OSAS发病的重要措施之一;长期鼻塞引发的OS-AS患者,早期通过鼻腔手术解除鼻塞是治疗OSAS的有效方法之一。
Objective: To investigate the effect of nasal obstruction on the incidence of obstructive sleep apnea syndrome (OSAS). METHODS: Eighteen OSAS patients diagnosed as obstructive nasal obstruction and velopharyngeal obstruction were treated with nasal surgery to improve ventilation and were followed up 6 months later. Results: The symptoms of sleep obstruction in 12 cases were relieved, of which 4 cases were effective and 6 cases were ineffective. The sleep apnea index (AHI) decreased from 29.9 ± 2.1 to 22.8 ± 2.7 preoperatively and nighttime oxygen saturation increased from (75.0 ± 2.9)% to (83.4 ± 2.3)%, while there was no significant difference in body mass index. There was significant difference between preoperative AHI values of invalid group and effective group. Conclusion: Nasal obstruction is an important causative factor of OSAS. Early treatment of nasal obstruction is one of the important measures to prevent the pathogenesis of OSAS. Long-term nasal obstruction in patients with OS-AS, early nasal surgery to relieve nasal congestion is one of the effective ways to treat OSAS.
