Hemifacial microsomia is a developmental abnormality involving structures derived from the first and second branchial arches. Microvascular transplants are increasingly being used to improve facial contour in patients with this condition. We have reviewed 9 patients with this abnormality to determine which recipient vessels have been used. In 6 patients, the facial vessels were located and used for flap revascularization. In 3 patients, the facial vessels could not be identified intraoperatively, and the occipital artery and a branch of the external jugular vein were used as recipient vessels. In this series of hemifacial microsomia patients, therefore, the facial vessels could not be located in 3 patients. We recommend that surgeons performing microsurgical transplants in cases of hemifacial microsomia be prepared to explore the external carotid and external jugular systems for recipient vessels.
半侧颜面短小畸形是一种涉及源于第一和第二鳃弓结构的发育异常。微血管移植越来越多地被用于改善患有这种病症患者的面部轮廓。我们回顾了9例患有这种异常的患者，以确定使用了哪些受区血管。在6例患者中，找到了面部血管并将其用于皮瓣再血管化。在3例患者中，术中未能识别出面部血管，枕动脉和颈外静脉的一个分支被用作受区血管。因此，在这组半侧颜面短小畸形患者中，有3例患者无法找到面部血管。我们建议，在半侧颜面短小畸形病例中进行显微外科移植的外科医生应准备好探查颈外动脉和颈外静脉系统以寻找受区血管。
