摘　　要：采用18只新西兰白兔制作双侧耳背游离皮瓣于术后48h、4天、7天、10天、2周及3周分别进行微血管塑料灌注铸型追踪观察皮瓣血供重建的变化过程。结果发现术后第2周开始出现少量切缘新生血管，至第3周方见广泛的吻合支，毛细血管通过其网络结构不断扩展形成连接，而中央动静脉及其分支则通过断端血管芽萌出，多点吻接而完成再通。In order to study the process of revascularization of free flap bilateral dorsal-auricular free flaps of 18 Newzealand rabbits were completed and investigated with the tech-nique of microvascular corrosion casting at 2, 4, 7, 10 days and 2, 4 weeks postoperatively. It was discovered that scarce neovascularity appeared around the margin of flap before 2 weeks following transplantation and extensive revascularization occured at 3 weeks postoperatively.The capillaries connected through their network expansion while central artery and vein formed recirculation by means of multiple point anastomoses of the 'vascular buds' sprouting up at both ends of vessels.
