成人阻塞性睡眠呼吸暂停综合征（ＯＳＡ）发病率为２％～４％［１］，外科手术为ＯＳＡＳ的主要治疗方法，如悬雍垂腭咽成形术（ＵＰＰＰ）、矢状位下颌骨切开颏舌肌前移（ＩＳＯ）、舌成形术、上下颌骨前移等，其中ＵＰＰＰ手术应用最为广泛，但据大量文献报道ＵＰＰＰ手术有效率仅为５０％左右［２］，效果不佳的主要原因是多数患者的上呼吸道有多水平面的阻塞，因此对ＯＳＡＳ患者阻塞部位的确切定位对于治疗方案的选择具有重要价值。 Adult obstructive sleep apnea syndrome (OSA) incidence of 2% to 4% [1], surgical treatment of OSAS is the main treatment methods, such as uvulopalatopharyngoplasty (UPPP), sagittal mandibular osteomyelitis Open the genioglossus muscle (ISO), tongue angioplasty, mandibular advancement, etc., of which the most widely used UPPP surgery, but according to a large number of reported UPPP effective rate of surgery was only about 50% [2], the effect is not good The main reason is that most patients have obstructions in the upper airway, so the exact location of obstructive sites in patients with OSAS is of great value for the choice of treatment options.
