Despite the importance of preoperative evaluation of small vessels in flap elevation, the conventional methods such as palpation or Doppler probes are technically insufficient. These two methods do not detect varying venous patterns that would be identified during the operation in a "trial-and-error" manner. In order to overcome this problem in the facial vessels, an anatomic study was done using color Doppler ultrasonography in 12 adults. The artery and the vein were located together at the lower border of the mandible. On the other hand, around the oral commissure, they were located apart from each other with variable distances and variable size of vein. This divergence of the facial vein from the artery is important information in the planning of axial pattern flaps. It is suggested that color Doppler ultrasonography is a useful tool for venous identification in every body region.
尽管术前评估皮瓣掀起中小血管很重要，但触诊或多普勒探头等传统方法在技术上存在不足。这两种方法无法检测到术中以“试错”方式才能发现的不同静脉模式。为了克服面部血管的这一问题，对12名成年人进行了彩色多普勒超声解剖学研究。动脉和静脉在下颌骨下缘处共同定位。另一方面，在口角周围，它们彼此分开，静脉距离和大小各不相同。面静脉与动脉的这种分离是轴型皮瓣规划中的重要信息。建议彩色多普勒超声是在身体各个部位识别静脉的有用工具。
