目的：对口唇段面动脉、面静脉及其分属支作解剖观测,为临床应用充实形态学数据。方法解剖经福尔马林固定的教学用成人尸体标本32例64侧,观测口唇段面动脉、面静脉及其分属支的起始、走行、分布、管径及相互位置关系等情况,对结果作相关分析。结果面动脉与面静脉在下颌骨下缘处位置关系不恒定。以下颌骨下缘与面动脉交界处为起点,左右两侧面动脉距口角、下颌角、颏隆凸中点等处的距离,左侧分别为(5.49±0.63) cm、(2.50±0.89) cm、(6.20±1.68) cm,右侧分别为(5.69±0.72) cm、(2.56±1.08) cm、(6.85±1.86) cm；在下颌骨下缘处面动脉管径左侧为(0.33±0.08) cm、右侧为(0.38±0.07) cm,面静脉管径左侧为(0.40±0.12) cm、右侧为(0.42±0.18) cm。口唇段面动脉与面静脉属支不一定同行,且左右基本不对称。上唇动脉位置较为恒定,下唇动脉存在较大变异。结论口唇段面动脉与面静脉走行、位置关系及其分(属)支变异较大；上唇动脉较下唇动脉更易于定位。熟悉血管分布情况对面部皮瓣移植及口唇部手术具有极大意义。

Objective To observe the oral part of the facial artery and facial vein and to provide anatomical data for clinical applica-tion. Methods The origin, branches, course, diameter, position of oral part of facial artery and facial vein were observed on 32 fixed cada-ves (64 sides). Results The position relation between the facial artery and facial vein is non-constant. Measure the distance from inferior border of mandible to corner of the mouth, angulus mandibulae, mental protuberance midpoint. It is (5. 49 ± 0. 63) cm, (2. 50 ± 0. 89) cm and (6. 20 ± 1. 68) cm in the left side respectively, and (5. 69 ± 0. 72) cm, (2. 56 ± 1. 08) cm and (6. 85 ± 1. 86) cm in the right side re-spectively. The diameter of facial artery in inferior border of mandible is (0. 33 ± 0. 08) cm in the left side and (0. 38 ± 0. 07) cm in the right side;while the diameter of facial vein is (0. 40 ± 0. 12) cm in the left side and (0. 42 ± 0. 18) cm in the right side. The facial artery and facial vein are not concomitant and they are not asymmetry also. The position of superior labial artery arteries is constant, but the position of inferior labial artery arteries have more variations. Conclusion The branches, course, diameter and position of oral part of facial artery and facial vein have a number of variations. The superior labial artery arteries could be positioned more easily than inferior labial artery arter-ies. Being familiar with their distribution is of great importance for clinical application.
