Abstract
The disfigurement of irreversible unilateral facial paralysis can be corrected by crossβface nerve grafting in conjunction with muscle transplantation. A total of 33 patients underwent crossβface nerve grafting using the sural nerve prior to undergoing the second stage of the procedure. Before a muscle transplant can be successfully connected to the distal end of the crossβface nerve graft, the regenerating axons need to have grown from the contralateral facial nerve to the distal end of the nerve graft. This can be tested by the Tinel sign. A retrospective study was performed to determine the rate of growth of regenerating axons through the crossβface nerve graft. A rate of axon growth of 1.8 mm/day was found, and also an inverse relationship between the age of the patient and the regeneration rate. These results can be used as a guide in planning patients' treatment. Β© 1993 WileyβLiss Inc.

## Abstract Poor recovery is seen after repair of long defects in peripheral nerves when denatured muscle grafts or regeneration chambers providing physical support alone are used. The presence of Schwann cells and neurotrophic factors is required for axons to migrate significant distances. In this
We investigated regeneration across a long nerve defect in the swine model to study extensive neural loss and long nerve gap. Most experiments have been conducted in the rodent model that, while an appropriate immunological model, only allows short nerve gaps to be studied. Twelve outbred swine rece
