Research Abstract

To clarify the usefulness of hypoglossal-facial anastomosis and accessory-facial anastomosis for facial rehabilitation when the facial nerve is sacrificed. We carried out hypoglossal-facial anastomosis and accessory-facial anatomosis in guinea pigs using classic hypoglossal-facial anastomosis method and Y-shaped silicone tube. Data obtained from both blink reflex measurement and histological study demonstrate a good quality of regeneration of the facial nerve from the hypoglossal nerve completed 6 months after the operation. In addition a new nerve bundle was regenerated from the proximal stump of the facial nerve connecting to the anastomotic site in 80% of the animals. The diameter of regenerated nerve bundle and number of axon in the hypoglossal-facial anastomosis were significantly greater than those of accessory-facial anastomosis at both 4 and 8 weeks postoperation. The conduction velocity of the hypoglossal-facial anastomosis was also faster than that of accessory-facial anastomosis. These results suggest that hypoglossal-facial anastomosis is more favorable surgical choice for facial rehabilitation than accessory-facial anastomosis.
