A Pilot Study Demonstrating the Feasibility of Supermicrosurgical End-to-Side Anastomosis Onto Large Recipient Vessels in Head and Neck Reconstruction

In head and neck reconstruction using free flaps, microvascular anastomosis is commonly performed in an end-to-end fashion to relatively sizable arteries including the superficial temporal, facial, and superior thyroid arteries. However, recent developments of less invasive perforator flaps such as the superficial circumflex iliac artery perforator flap, anastomosis of smaller vessels that are less than 0.8 mm in diameter has become necessary; however, appropriate recipient arteries for end-to-end anastomosis are often absent.
