This article reported the implantation of the greater auricular nerve into the cervicoshoulder skin flap in rabbits. The progress following implantation of the nerve was continuously observed. According to the time elapsed from the nerves
being implanted, the experimental animals were divided into 4 groups, 4 animalsin each group, in the order of 1, 2, 4 and 6 months groups, respectively, and the normal skin and the cervicoshoulder skin flaps without nerve implantation were used as control. The electron microscope was the method used to observed theprogress. The results showed that in the 2nd month the unmyelinated fibers first appeared, then the myelinated in the 4th month. The caliber of the axons, the thickness of the myelin sheath and the ratio of MF/UF increased with time. In the 4th month, the number of the regenerating nerve fibers (unmyelinated fibers predominant) had achieved the highest level and significantly exceeded that of thenormal skin. But at the 6 months. the MF/UF ratio was still for lower than normal.
