Laser nerve repair by solid protein band technique. II: assessment of long-term nerve regeneration.
A total of 18 adult male Wistar rats had left tibial nerve repaired by either the laser-solder technique or a more conventional microsuture technique. The diode laser power was 90 mW and the radiation dose 16 J/mg. Three months postoperatively electrophysiology showed that the average compound muscle action potential (CMAP) of the laser repair group was not significantly different from the CMAP of the sutured nerves. Light microscopy confirmed regeneration of myelinated axons in both groups of animals. The laser-solder technique, when used with such parameters, proved to be a reliable method to achieve satisfactory peripheral nerve anastomosis and nerve regeneration.
