Resumen:
The effect of electric field stimulation for promoting axonal growth between sural-to-facial nerve grafts in cases of permanent facial palsy was studied. For this purpose a total of 14 patients with unilateral permanent facial palsy were studied pre- and postoperatively. A sural-to-facial nerve graft was performed in all cases and long-term postoperative electric field stimulation was randomly applied to half of the patients. Although improvement occurred in both groups, the results indicated that clinical and electrophysiological recovery was significantly better in patients receiving postoperative electric field stimulation. The results suggest that electric field stimulation in patients subjected to sural-to-facial grafts induces an additional improvement over the non-stimulated patients.
