Degenerative and regenerative processes in the peripheral nerve after disconnection and reanastomosis using the Neodym Yag laser.

The development of neuroma after peripheral nerve surgery is still an unsolved problem. Such lesions are not yet controllable by conventional methods. Reports of results achieved using various types of laser surgery appear contradictory. In this experimental study on rats, the Neodym Yag laser was found to be superior the conventional methods. After severance and reanastomosis of the sciatic nerve using this type of laser, no development of neuroma was observed in any of the animals during the first three months of observation.
