Twenty adult healthy rabbits were divided into 2 groups at random. Under the identical experimental conditions, cut the trunk of the right facial nerve. Two weeks later. the caudal end of the divided facial nerve was anastomized with the cephalad end of the divided main trunk of the nerve to the masseter muscle. The experimental group was stimulated by music, twenty minutes of each time, three times a day. From the results it was noted that the rate of growth of the nerve in the experimental group was more rapid than that of the contril group.
