The effect of freezing on peripheral nerve repair

It has been suggested that where a double lesion to a peripheral nerve exists, the results of regeneration of the nerve is actually improved. This has been studied by comparing the results of nerve section and repair with and without an accompanying second lesion in the form of freezing of the nerve proximal to the anastomosis. While the effects of freezing does not adversely affect the results of nerve repair it has not been shown to produce any significant improvement.
