One-stage reconstruction for bilateral Möbius syndrome: simultaneous use of bilateral spinal accessory nerves to innervate 2 free muscles for facial reanimation.

Möbius syndrome (MS) can present with unilateral or bilateral facial paralysis. In performing 1-stage bilateral MS facial reanimation, we used bilateral spinal accessory (XI) nerves to innervate 2 free functional muscle transfers (FFMTs). Of 12 MS patients, 6 had bilateral facial paralysis. Bilateral gracilis were transferred and innervated using bilateral XI nerves. Results were evaluated using smile excursion score, cortical adaptation stage, and patient satisfaction questionnaire. In all, 13 FFMTs were performed (with 1 gracilis failure). Mean smile excursion score improved from 0.7 to 3.4 (out of 5) postoperatively. Four patients achieved spontaneous smile, 1 achieved independent smile, and 1 achieved dependent smile. Mean satisfaction score was 2.8 (out of 5). One-stage bilateral FFMTs neurotized by bilateral XI nerves are effective in treating bilateral MS patients. Careful patient selection, adequate neurologic and psychologic examination, and postoperative smile training are all important factors in achieving optimal outcomes.
