| Research Abstract |
Cross-Link nerve grafting technique between facial nerve and hypoglossal nerve with grafted sensory nerve for facial nerve palsy has demonstrated effectiveness in patients. This is very interesting surgical method, though no basic research has been performed to analyze the newly formed neural circuit. We constructed the rat cross-link nerve grafted model and introduced the neural tracer method. In our experiment, anterograde labeling showed that axons of hypoglossal neuron pass through the grafted nerve and extend to facial nerve bundle. On the other hand, in retrograde labeling study, axons from facial nucleolus extend to hypoglossal nerve bundle and from hypoglossal nucleous to facial nerve bundle. These data suggest that crossing of axons are caused by the Cross-Link nerve grafting.
