To investigate the therapeutic effects of upper airway stenosis after Le Fort III osteotomy and midfacial distraction osteogenesis (DO).
Eleven cases (age, 5-16 yrs) with severe midface dysostosis complicated with exophthalmos, anterior crossbite and upper airway stenosis were treated by using Le Fort III osteotomy and midfacial DO from August 2000 to February 2007. The 3D reconstruction of the upper-airway from CT data was used to evaluate the upper airway volume before and after the operation. And meanwhile polysomnography was carried out to demonstrate the upper airway functional changes.
There was a 64.3% mean increase [mean, (9.13 +/- 6.94) ml, P < 0.05] in upper airway volume in the 11 cases after the operations. It showed that there was significant improvements in the indexes of polysomnography after the operations, such as apnea and hypopnea index, average SaO2, minimum oxygen saturation and snore index.
The Le Fort III osteotomy and midfacial distraction osteogenesis can efficiently relieve the symptoms of upper-airway stenosis in severe midfacial dysostosis.
探讨勒福Ⅲ型截骨术联合面中部牵引成骨术（DO）治疗上气道狭窄的疗效。
2000年8月至2007年2月，对11例（年龄5 - 16岁）患有严重面中部发育不全并伴有眼球突出、前牙反合及上气道狭窄的患者采用勒福Ⅲ型截骨术联合面中部DO进行治疗。利用CT数据对上气道进行三维重建，以评估手术前后上气道容积。同时进行多导睡眠监测以显示上气道功能变化。
11例患者术后上气道容积平均增加64.3%[平均值，(9.13±6.94)ml，P < 0.05]。结果显示，术后多导睡眠监测指标如呼吸暂停低通气指数、平均SaO₂、最低血氧饱和度及打鼾指数均有显著改善。
勒福Ⅲ型截骨术联合面中部牵引成骨术可有效缓解严重面中部发育不全患者的上气道狭窄症状。
