上呼吸道成像技术有助于确定阻塞性睡眠呼吸暂停(OSA)患者梗阻的确切位置和性质。对10例OSA患者和10例非OSA对照组进行锥束CT(NewTom QR-DVT9000)扫描，比较其上呼吸道结构。阻塞性睡眠呼吸暂停综合征患者的体重指数较高(阻塞性睡眠呼吸暂停综合征：29.5±9.05 kg/m(2)；非阻塞性睡眠呼吸暂停低通气综合征患者：23.1±3.05 kg/m(2)[P=0.34])，气道总容量(mm(3))较低(阻塞性睡眠呼吸暂停低通气综合征：4868.4±/-1863.9；非阻塞性睡眠呼吸暂停低通气综合征组：6051.7+/-1756.4[P=0.054])，最小横截面积的前后径(Mm)显著小于非阻塞性阻塞性睡眠呼吸暂停低通气综合征组(4.6%±-1.2%)；非OSA7.8+/-3.31[P=.009]，最小截面积较小(OSA45.8+/-17.5 mm(2)；非OSA7.8+/-111.7 mm(2)[P=.011])，位于咬合面以下者占70%(OSA7/10；非OSA5/10[P=.030])。OSA组呈凹形或椭圆形，非OSA组呈凹形、圆形或方形。
Upper airway imaging techniques can be useful to identify the exact location and nature of the obstruction in obstructive sleep apnea (OSA) patients. Ten OSA patients and 10 non-OSA control subjects were imaged using cone-beam computed tomography (NewTom QR-DVT9000) to compare their upper airway structure. The OSA subjects presented higher BMI (OSA: 29.5 +/- 9.05 kg/m(2); non-OSA: 23.1 +/- 3.05 kg/m(2) [P = 0.34]), lower total volume (mm(3)) of the airway (OSA: 4868.4 +/- 1863.9; non-OSA: 6051.7 +/- 1756.4 [P =.054]), statistically significantly smaller anterior-posterior dimension (mm) of the minimum cross-section segment (OSA: 4.6 +/- 1.2; non-OSA: 7.8 +/- 3.31 [P = .009]), and smaller minimum cross-section area (OSA: 45.8 +/- 17.5 mm(2); non-OSA: 146.9 +/- 111.7 mm(2) [P = .011]) positioned below the occlusal plane in 70% of the cases (OSA:7 out of 10; non-OSA: 5 out of 10 [P = .030]). The OSA group presented a concave or elliptic shaped airway and the non-OSA group presented a concave, round, or square shaped airway.
