To determine the relationship between the lingual artery and lingual markers for preoperative evaluation of the lingual artery in patients with obstructive sleep apnoea/hypopnoea syndrome (OSAHS).
A 16-section computed tomographic angiography (CTA) of the lingual artery was performed in 87 inpatient cases with OSAHS, from December 2007 to May 2009. The course of the lingual artery and the anatomic relationship between the lingual artery and the lingual markers were analyzed using CTA imaging.
The course of the lingual artery with the tongue in a resting position was similar to that of the Big Dipper constellation (Plough) in the sagittal view of CTA imaging. The first segment of the lingual artery declined approximately 19.27 ± 5.24 mm, the middle segment of the lingual artery was forward approximately 19.30 ± 6.79 mm, and the ascending segment of the lingual artery rose approximately 52.49 ± 10.98 mm. The entry point where the lingual artery entered into the tongue was adjacent to the tip of the greater horn of the hyoid bone. The relationship between the second segment of the lingual artery and the greater horn of the hyoid bone was relatively steady with the tongue in whatever position. The interval between the bilateral greater horn of the hyoid bone equalled that between the bilateral lingual arteries.
Recognizing some lingual markers in the patients with OSAHS, such as the greater horn of the hyoid bone, foramen cecum, circumvallate papilla, lingual vein and tongue midline, may facilitate the surgeon's ability to define the course of the lingual artery accurately in the treatment of OSAHS.
探讨阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者舌动脉与舌体解剖标志的关系，为术前评估舌动脉提供参考。
回顾性分析 2007 年 12 月至 2009 年 5 月间 87 例 OSAHS 患者的 16 层螺旋 CT 血管造影（CTA）资料。分析舌动脉的行程及其与舌体解剖标志的关系。
在 CTA 矢状位图像上，安静状态下舌动脉与舌体的位置关系类似于北斗七星（Plough）的形状。第一段舌动脉下降约 19.27 ± 5.24mm，中段舌动脉向前走行约 19.30 ± 6.79mm，上升段舌动脉上升约 52.49 ± 10.98mm。舌动脉入舌起始部位于舌骨大角尖端附近。第二段舌动脉与舌骨大角的关系在舌体任何位置都相对稳定。双侧舌骨大角之间的距离与双侧舌动脉之间的距离相等。
熟悉 OSAHS 患者舌体的一些解剖标志，如舌骨大角、茎突舌骨韧带、轮廓乳头、舌静脉和舌中线等，有助于术者在治疗 OSAHS 时准确判断舌动脉的行程。
