Abstract

Twenty-four cross bred adult dogs were separated into four groups and submitted to bilateral neurotomy of the radial nerve, at the level of the distal third of the humerus. In each dog the epineural anastomosis was made 21 days after neurotomy. The surgical region of the left forearm received daily irradiation with GaAs laser for a ten day period in order to evaluate its influence on the repair process. The right forearm was the control. Functional recovery of the forearms was evaluated through ambulation, test of sensibility and motion evaluation. Nerve regeneration was confirmed by histological studies of the anastomosed nervous stumps, collected by biopsy in the 10th day (group A), in the 30th day (group B), in the 60th day (group C) and in the 90th day (group D) after neuroanastomosis. The histological studies showed that the proliferation of the connective tissue on the anastomosis region was the factor that proved to be the greatest impeachment for the nervous regeneration. The GaAs laser radiation decreases the local inflammatory response but may contribute to neuroma formation.
