The purpose of this study was to provide the guidelines with respect to the location of the facial vessels, observe the potential reversed flow of the facial artery, and reemphasize the value of color Doppler ultrasound studies in flap planning.
A study was carried out to investigate the location and dynamics of the facial artery and vein using color Doppler ultrasonography in 12 adults.
The facial artery and the vein were located together at the lower border of the mandible. Around the oral commissure and under the nasal ala, they run apart from each other at variable distances. The reverse flow was observed in the 12 patients after the blood flow of the facial artery was blocked by applying pressure manually at the lower border of the mandible.
The divergence of the facial vein from the artery is important information in planning of axial pattern flaps. Observation of the reversed flow confirms the possibility of safe elevation of a retrograde flow-arterialized flap based on the distal portion of the facial artery.
本研究旨在提供关于面部血管位置的指南，观察面动脉的潜在逆流情况，并再次强调彩色多普勒超声检查在皮瓣规划中的价值。
对12名成年人进行研究，使用彩色多普勒超声检查来研究面动脉和静脉的位置及动态情况。
面动脉和静脉在下颌骨下缘处共同走行。在口角周围和鼻翼下方，它们以不同距离相互分开。在下颌骨下缘手动施加压力阻断面动脉血流后，12名患者均观察到逆流情况。
面静脉与动脉的分离是轴型皮瓣规划中的重要信息。对逆流的观察证实了基于面动脉远端安全掀起逆行血流动脉化皮瓣的可能性。
