Abstract

After axotomy of a peripheral motor nerve, structural alterations of Nissl’s substance in the neuron are observed. This reaction — classically termed chromatolysis — is considered as a response to the changed metabolism of the injured neuron; its regeneration seems to cause restoration of Nissl’s substance. We performed a quantitative investigation of Nissl’s substance in the facial and hypoglossal nucleus after hypoglossal-facial anastomosis (HFA) in comparison to facial-facial (FFA), hypoglossal-hypoglossal (HHA) anastomosis, and resection of the nerves.
