To study modified rat laryngeal transplantation model.


Eighty isogeneic histocompatible F344 rats were randomized into control and experimental groups. Strome model of laryngeal transplantation was established in the the control group, and in the experimental group, the ascending pharyngeal artery was preserved and the base of the tongue, larynx and pharyngolarynx were harvested as a complex allograft followed by end-to-end anastomosis of the both allograft common carotid arteries with the recipient common carotid artery and the anterior jugular vein, respectively. The arterial and nenous patency rate and allograft viability rate were compared between the two groups.


The artery and vein patency rates and graft survival rate were 30%, 15%, and 30% in the control group, and 75%, 65%, and 80% in the experimental group, respectively, showing significant difference between the two groups (P<0.05).


In modified rat laryngeal transplantation model, the allograft viability rate and vessel patency rate are improved, which provides a good model for immunological study of larynx transplantation.
