IntroductionMöbius syndrome is defined as a combined congenital bilateral facial and abducens nerve palsies. The main goal of treatment is to provide facial reanimation by means of a dynamic surgical procedure. The microneurovascular transfer of a free muscle transplant is the procedure of choice for facial animation in a child with facial paralysis.ObservationBetween January 2008 and January 2017, 124 patients with the syndrome have been approached at our institution. Distribution according to Möbius Syndrome classification presents as follows: Complete Möbius syndrome (n=88), Incomplete Möbius syndrome (n=28), Möbius-Like syndrome (n=8). Seventy-nine female and 45 male patients. Sixty-one percent have undergone a microsurgical procedure (n=76), in all of them, a free gracilis flap transfer was performed.DiscussionOur proposed treatment protocol for complete Möbius syndrome is determined by the available donor nerves. We prefer to use the masseteric nerve as first choice, however, if this nerve is not available, then our second choice is the spinal accesory nerve. For this purpose, all patients have an electromyography performed preoperatively. Overall, dynamic facial reanimation obtained through the microvascular transfer of the gracilis muscle have proved to improve notoriously oral comissure excursion and speech intelligibility.ConclusionThe free gracilis flap transfer is a reproducible procedure for patients with Möbius syndrome. It is of utmost importance to select the best motor nerve possible, based on an individualized preoperative clinical and electromyographic evaluation. To our best knowledge, this is the largest series of patients with Möbius syndrome globally, treated at a single-institution.
