Results: Typical was 26 patients, 37 patients. new face sensory disturbance reported after 16% 27% (p = 0.4). Thirteen failed whereas seven dose. Kaplan–Meier analysis found at 29 months 50% compared 79% who had durable 0.04). Conclusion: more one without significantly elevated occurrence disturbance.
