    Background: In facial reanimation via microneurovascular muscle transfer, dual-nerve reinnervation of the muscle capitalizes on the synergistic effects of spontaneous motion from cross facial nerve grafting (CFNG) and increased excursion from masseteric nerve transfer. Two-stage approaches that delay masseteric nerve transfer until the time of the muscle flap increase spontaneity by maximizing muscle reinnervation from the CFNG. While this 2-stage, dual-nerve approach has been described in adults, we present a series of pediatric patients who underwent this reconstructive technique. Methods: We retrospectively reviewed all pediatric patients who underwent 2-stage, dual-nerve reconstruction with CFNG and ipsilateral masseteric nerve transfers. Procedures were performed between 2004 and 2016 by 2 surgeons at a single centre. Degree of facial paralysis before and after surgical intervention was measured using House-Brackmann scores. Results: Nine patients with a mean age of 8.6 (range: 5-15 years) years at time of surgery underwent 2-stage, dual-nerve reconstruction. Average time between CFNG and transfer of the free gracilis with masseteric nerve transfer was 13.3 (SD 2.4) months. Mean follow-up was 27.3 months (SD 25.7). Patients demonstrated initiation of voluntary movement on paralyzed side by 3.6 months (SD 0.6) on average, with 3 patients demonstrating spontaneous movement at 3 months. Conclusion: The 2-stage, dual innervation technique using CFNG and delayed ipsilateral masseteric nerve transfer with a free gracilis is a promising reconstructive option to maximize spontaneous expression in pediatric patients. Validated, objective scoring systems for excursion are needed before meaningful comparisons can be made to other reconstructive strategies.
