摘　　要：①目的　探讨超快速磁共振成像(MRI)在阻塞性睡眠呼吸暂停综合征(OSAS)病人阻塞部位的确定、手术疗效预测中的作用。②方法　以多导睡眠图(PSG)检查定性,分别对 15 例行悬雍垂腭咽成形术(UPPP)的OSAS病人术前进行MRI检查、鼻咽纤维喉镜检查配合Müller s运动检查(FEMM)。对超快速 MRI检查结果与UPPP手术疗效的关系、超快速MRI检查结果与FEMM检查结果进行相关回归分析。③结果　超快速MRI检查显示,阻塞位于软腭区(SP)4例,软腭区+舌根区(LR)8 例,软腭区+舌根区+会厌区(EP)3 例。UPPP术后治愈[术后睡眠呼吸暂停低通气指数(AHI) < 50] 3 例,阻塞部位均位于 SP 区;有效(术后 AHI 较术前减少超过50%)5例,阻塞位于SP区1例,位于SP+LR区3例,位于SP+LR+EP区1例;无效7例,阻塞位于SP+LR区5例,SP+LR+EP区2例。相关回归分析证实,15 例病人超快速 MRI和 FEMM检查结果具有相关性(r=0.19,P<0.01)。④结论　应用超快速MRI可以确定阻塞部位,对OSAS病人UPPP手术筛选、预测手术疗效具有重要的参考价值。Objective To determine the ultrafast MRI examination in locating the obstructive sites in patients with obstructive sleep apnea syndrome(OSAS). Methods A total of 15 patients with OSAS underwent ultrafast MRI examination and their PSG findings were analyzed by apnea hypopnea index(AHI). A fibrolaryngoscopy combined with Müller's maneuver (FEMM) was used before operation of UPPP. The results between MRT and the therapeutic efficacy of UPPP; the findings of FEMM and ultrafast MRI were compared. Results After UPPP, three patients' AHI was less than five, five patients' AHI dropped more than 50%, and seven patients showed ineffective. UPPP succeeded when MRI findings showed the obstructive sites were in SP. UPPP was less useful while the obstructive sites were more than one. Compared with findings in MRI and FEMM showed there were correlations between them. Conclusion Ultrafast MRI can locate the obstructive sites in OSAS patient, which is of important reference value in screening and predicting the operation of UPPP.
