Abstract:
Objective:To develop a modified rat laryngeal transplantation model to improve the survival rate of recipients.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.Results: The artery,vein patency rate and survival rate were 30%,15%,and 30% in control group,and 75%,65%,and 80% in experimental group,respectively(P
