To determine the relationships between the lingual artery and the lingual markers in tongue resting and extended positions in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) for the clinical application of functional tongue surgery.
Computed tomography angiography (CTA) of the lingual artery was performed on 30 OSAHS patients using a 16-slice spiral CT scanner. The anatomical relationships between the lingual artery and the lingual markers were analyzed with the tongue in resting and extended positions using the CTA images.
The course of the lingual artery resembled the configuration of the Big Dipper constellation when the tongue was in a resting position. When the tongue was in a full-extended position, the majority of the lingual artery moved forward and upward with the hyoid and formed a "√" fashion. The positions of the tip of the greater horn of the hyoid changed with the tongue positions. While the relationship between the main lingual artery and the tip of the greater horn of the hyoid, as well as the distances between bilateral lingual arteries, remained constant in both tongue positions.
In conditions of dynamic tongue movement, the tip of the great horn of the hyoid and the lingual midline are constant anatomical markers to indicate the course of the lingual artery.
确定阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者舌处于静息位和伸展位时舌动脉与舌部标志之间的关系，以用于功能性舌手术的临床应用。
使用16层螺旋CT扫描仪对30例OSAHS患者进行舌动脉的计算机断层血管造影（CTA）。利用CTA图像分析舌处于静息位和伸展位时舌动脉与舌部标志之间的解剖关系。
当舌处于静息位时，舌动脉的走行类似北斗七星的形态。当舌处于完全伸展位时，大部分舌动脉随舌骨向前上方移动，呈“√”形。舌骨大角尖端的位置随舌位改变。而在两种舌位下，舌动脉主干与舌骨大角尖端的关系以及双侧舌动脉之间的距离保持不变。
在动态舌运动情况下，舌骨大角尖端和舌中线是指示舌动脉走行的恒定解剖标志。
