Abstract： 目的 分析评价下颌骨牵引延长技术治疗小下颌畸形伴阻塞性睡眠呼吸暂停综合征(obstructive sleep apnea syndrome,OSAS)后,患者上呼吸道、睡眠呼吸暂停指数及血氧的变化.方法 对5例小下颌畸形伴OSAS患者应用口内型牵引器行下颌骨牵引成骨延长下颌骨体、前伸下颌骨、扩大咽腔.结果 5例下颌骨体最大牵引幅度为24.40 mm,最小牵引幅度8.50 mm.在小颌畸形得到明显改善的同时,患者咽腔扩大,睡眠呼吸暂停指数明显下降,血氧饱和度显著上升.最长随访时间11个月,无复发.牵引过程中未出现牵引器松脱、未成骨或骨缝过早联合等现象.结论 与以往的小下颌畸形伴OSAS的手术治疗相比,下颌骨牵引延长术不但手术创伤小、操作简单、避免了植骨及由此带来的供、受区并发症,而且其下颌前移、咽腔扩大的效果更为明显且稳定.具有重要的应用及推广价值.
