Research Abstract	The purpose of this study is to clarify whether flow-in end-to-side nerve anastomosis can prevent denervation atrophy of the muscle. In rats, the zygomatic branch was anastomosed with the side of the buccal branch, which was cut and immediately sutured at one or two portions proximal to the anastomotic site. Then, after the some period, the zygomatic branch was cut(donor release). As a result, the number of the regenerated axons was less distally than proximally to the anastomotic site in the one-portion-cut group, while it was more distally than proximally in the two-portions-cut group. It is recommended that flow-in end-to-side nerve anastomosis accompanied by donor release is recommended only for the nerve with severe damage
