Silensor阻鼾器治疗前后阻塞性睡眠呼吸暂停综合征患者上气道结构改变的分析

目的 探讨Silensor阻鼾器治疗前后阻塞性睡眠呼吸暂停综合征(OSAS)患者上气道结构的改变。方法 采用X线头影测量法对42例OSAS患者Silensor阻鼾器治疗前后的上气道及其周围结构的形态进行测量，并对测量的42项结果进行配对t检验。结果 经阻鼾器治疗后，OSAS患者的软腭后气道增大最显著，软腭后-软腭后咽壁距由（9.10±2.25） mm 增加到（12.24±2.61） mm，舌根后气道间隙由（8.99±3.20） mm增至（11.24±3.79） mm，软腭与舌体接触长度由（26.26±6.04） mm 减小至（14.37±8.14） mm，舌骨-下颌平面距由（21.27±6.12） mm减小为（12.14±5.89） mm，会厌谷与颏后点间的距离由（55.15±5.61） mm减小为（51.63±5.87） mm。口咽气道面积和喉咽气道面积分别由（7.01±1.54） mm2和（3.02±0.89） mm2增大为（7.85±1.61） mm2和（3.61±1.61） mm2。结论 Silensor阻鼾器治疗后OSAS患者的上气道间隙明显增大。

Changes of Upper Airway of Obstructive Sleep Apnea Syndrome Patients after the Treatment of Silensor Snoreguard

OBJECTIVE: To investigate the changes of upper airway of obstructive sleep apnea syndrome (OSAS) patients after the treatment of Silensor snoreguard. METHODS: 42 patients with OSAS were treated with dental appliance. Cephalometric analysis was carried out to compare the changes of upper airway before and after the treatment. RESULTS: SPP-SPPW increased from (9.10 +/- 2.25) mm to (12.24 +/- 2.61) mm. PAS increased from (8.99 +/- 3.20) mm to (11.24 +/- 3.79) mm. CL decreased from (26.26 +/- 6.04) mm to (14.37 +/- 8.14) mm. H-MP decreased from (21.27 +/- 6.12) mm to (12.14 +/- 5.89) mm. V -RGn decreased from (55.15 +/- 5.61) mm to (51.63 +/- 5.87) mm. OPAA increased from (7.01 +/- 1.54) mm2 to (7.85 +/- 1.61) mm2. HPAA increased from (3.02 +/- 0.89) mm2 to (3.61 +/- 1.61)mm2. CONCLUSION: Dental appliance worked with the effect of enlarging upper airway.
