Transplantation of the superiorly based pharyngeal flap was performed in young beagles, 99 to 110 days old, and pathohistological and neurohistological examinations were made of the healing process of the lesion. The results were as follows : 1. The epithelium at the adhesion site was extremely thin 30 days after operation but reached the normal thickness in about 180 days. 2. Infiltration of the inflammatory cells in the proper layer of the mucous membrane at the adhesion site was hardly observed in 90 days. 3. The diameter of the regenerated nerve fibers after severence increased with time and was nearly normal in 180 days. 4. Schwann cells had a great part in every instance of the regenerated nerve fibers. 5. Most of the regenerated nerve fibers running through the adhesion site regenerated and grew from the pharyngeal flap side. 6. The nerve endings were observed in the regenerated nerve fibers in 30 days. 7. The form of the nerve endings was mostly free nerve endings except that in part of the fibers it was glomerulus in 30 days, and smple ramified nerve endings with arborescence in 90 days, and glomerulus and simple ramified nerve endings with arborescence in 180 days.
