目的研究不同下颌前伸量对无鼾人群和阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者用力吸气流量(forced inspiratory airflow,FIF)的影响,探讨口腔矫治器治疗OSAHS的有效下颌前伸量.方法无鼾人群和OSAHS患者各18例分别在仰卧位和侧卧位进行不同下颌前伸量的FIF测定:下颌正中位(下颌前伸0％)、下颌前伸25％、下颌前伸50％和下颌前伸75％.测量结果换算成百分比值后取平均值((x)±s)进行单因素方差分析和配对t检验.结果无鼾人群不同体位,不同下颌前伸量的FIF百分比值之间差异均无统计学意义(P值均＞0.05).OSAHS患者在仰卧位及侧卧位,下颌前伸50％的FIF比值(107.1％±29.0％,112.0％±33.1％)和75％的FIF比值( 106.4％±20.7％,116.8％±36.4％)均显著高于下颌前伸0％的FIF比值(84.0％±18.3％,98.3％±24.0％)和25％的FIF比值(92.7％±21.8％,103.7％±22.6％),P值均＜0.05；但50％和75％两位置间差异均无统计学意义(P值均＞0.05).相同下颌前伸量时,仰卧位和侧卧位的FIF之间差异无统计学意义(P值均＞0.05).结论下颌前伸50％和前伸75％对于OSAHS患者的通气改善无明显区别,下颌前伸50％可考虑作为口腔矫治器治疗OSAHS的有效前伸量.

Objective To study the effect of different jaw forward distance on forced inspiratory airflow(FIF) in non-apnea subjects and patients with obstructive sleep apnea hypopnea syndrome (OSAHS)and to evaluate the effective jaw forward distance for the treatment of OSAHS with the oral appliance.Methods FIF was measured in 18 non-apnea subjects and 18 OSAHS patients at supine and lateral body positions with different jaw forward distances (the percentages of maximum jaw forward distance): 0％,25％,50％ and 75％.FIF were converted to percentage values(FIF％,(x) -±s) followed by averaged.Then the results were analyzed by one-way analysis of variance and paired t-test with α =0.05.Results For nonapnea subjects,there was no significant difference in the FIF values between different jaw forward distances as well as different body positions.For OSAHS patients,the mean FIF％ at supine and lateral body positions were 107.1％ ±29.0％ and 112.0％ ±33.1％ at jaw forward 50％,and were 106.4％ ±20.7％ and 116.8％ ±36.4％ at jaw forward 75％,respectively,which were significantly higher than those (84.0％ ± 18.3％ and 98.3％ ± 24.0％ ) at jaw forward 0％ or those (92.7％ ± 21.8％ and 103.7％ ± 22.6％ ) at jaw forward 25％,respectively.But there was no statistical difference in FIF between the two groups of jaw forward 50％ and jaw forward 75％ and no statistical difference in FIF between supine and lateral body positions in the same forward position.Conclusion Jaw forward 50％ is a effective jaw forward distance by oral appliance for the treatment of OSAHS and can improve the airway ventilation in OSAHS patients.
