Methods Eighty Class Ⅱ isogeneic F344 rats, weighing 250-350 g, were randomly divided into 2 groups(n=40). The control group adopted the Strome model. The allograft used for the experimental group preserved ascending pharyngeal artery, which formed a complex allograft together with tongue base, larynx and pharyngolarynx. End-to-end anastomosis was performed between both allograft common carotid arteries and anterior neck veins. The patency rate and survival rate of the allograft of the 2 groups were compared.
