摘　　要：目的 观察半张口位超声探查上颌动脉(MXA)及脑膜中动脉(MMA)的价值。方法 前瞻性招募40名健康志愿者,分别行半张口位和闭口位经颞下窝彩色多普勒超声及头颈部CT血管造影(CTA),观察其所示双侧MXA及MMA,测量内径及血流动力学参数;以CTA为对照,评估超声探查MXA及MAA的价值。结果 半张口位超声对于MXA和MMA显示率分别为95.00%(76/80)和90.00%(72/80);而闭口位超声显示率分别为75.00%(60/80)和60.00%(48/80)。半张口位与闭口位对于MXA和MMA的显示率差异均有统计学意义(P均<0.05)。MXA内径、收缩期峰值流速(PSV)及舒张末期流速(EDV)均显著大于MMA,而阻力指数(RI)及搏动指数(PI)小于MMA(P均<0.05)。半张口位及闭口位CTA中,MXA显示率均为100.00%(80/80),MMA显示率均为95.00%(76/80);且半张口位超声与CTA对于MXA及和MMA的显示率差异均无统计学意义(P均>0.05)。CTA显示76条MXA走行于翼外肌下头浅面,4条MXA走行于翼外肌下头深面并与同侧MMA伴行直至MMA进入棘孔,且均未被半张口位超声所显示。结论 半张口位超声可用于探查MXA和MMA,显示率均与CTA相当。Objective To observe the value of half-open mouth position ultrasound for detecting maxillary artery(MXA)and middle meningeal artery(MMA).Methods Forty healthy volunteers were prospectively recruited.Color Doppler ultrasound through infratemporal fossa,as well as and head and neck CT angiography(CTA)were performed under closed mouth and half-open mouth positions,respectively.Bilateral MXA and MMA were observed,and the internal diameter and hemodynamic parameters of MXA and MMA were measured.Taken CTA findings as references,the value of ultrasound for detecting MXA and MAA was analyzed.Results The display rate of MXA and MMA of half-open mouth position ultrasound was 95.00%(76/80)and 90.00%(72/80),respectively,while of closed mouth position ultrasound was 75.00%(60/80)and 60.00%(48/80),respectively.There were significant differences of ultrasound display rates of MXA and MMA between closed and half-open mouth positions(both P<0.05).The inner diameter,peak systolic velocity(PSV)and end diastolic velocity(EDV)of MXA was all significantly higher than those of MMA,while its resistance index(RI)and pulsatile index(PI)was lower than those of MMA(both P<0.05).The display rates of MXA in CTA under both closed and half-open mouth positions were both 100.00%(80/80),while of MMA were both 95.00%(76/80).Under half-open mouth position,there was no significant difference of display rate of MXA and MMA between ultrasound and CTA(both P>0.05).CTA showed 76 MXA run on the superficial surface of the lower head of lateral pterygoid muscle,while other 4 run on the deep surface of the lower head paralleled to the ipsilateral MMA until MMA entered into foramen spinosum,which were not displayed with half-open mouth position ultrasound.Conclusion Half-open mouth position ultrasound was feasible for detecting MXA and MMA,with display rates similar to CTA.
