BACKGROUND: Facial palsy may have deleterious effects for pediatric patients. The most common reconstruction is 2-stage free gracilis muscle transfer (FGMT) after cross-face nerve graft (CFNG). This requires a prolonged period from time of surgery to smile. New techniques using both a CFNG and motor nerve to masseter (MNM) as dual power sources in a single-stage surgery have been described in adults. Here, we examine our experience with this technique in children.
METHODS: A retrospective study was performed examining patients who underwent dual-innervated single-stage FGMT at 2 pediatric hospitals from 2016 to 2019. Demographics, etiology, perioperative characteristics, time to mandibular and emotional smile, and Sunnybrook scores were recorded.
RESULTS: Five patients met inclusion criteria with a mean age of 11.8 (range, 8-20). Two patients had congenital facial palsy while 3 had acquired facial palsy. Four patients (80%) received dual end-to-end neural coaptations of the CFNG and MNM to the obturator nerve. One (20%) had end-to-side coaptation of the CFNG to the obturator nerve and end-to-end of the MNM to the obturator nerve. The average time to mandibular smile was 103 ± 15.4 days. The average time to emotional smile was 245 ± 48.1 days. The preoperative Sunnybrook scale was 32 ± 7.5 and improved to 55.3 ± 20.6 at 8 months postoperatively.
CONCLUSIONS: Dual-innervated FGMT is effective for facial reanimation in children with unilateral facial palsy. Patients can harness a stronger motor source (MNM) and the component of an emotional stimulus (CFNG). This approach may be the new criterion standard pediatric facial reanimation.
