Highlights
The Möbius syndrome (MS) was first described in 1880 by von Graefe and Saemisch, and in a more complete fashion in 1888
The Möbius Syndrome is a rare syndrome, with a 1/150 000 prevalence, that allows for different microsurgical and non-microsurgical techniques to correct the facial paralysis, and the strabismus of the patients
Since it is not always possible to perform microsurgical techniques on all patients, muscle transfer is a good alternative, whether it is of the gracilis muscle, the masseter, or the temporal muscle, as long as a vascularized muscle transfer is made, and that allows for the innervation with the facial nerve, so as to obtain a more natural smile
Summary
The Möbius syndrome (MS) was first described in 1880 by von Graefe and Saemisch, and in a more complete fashion in 1888. MS can be classified as classic MS, characterized by facial paralysis (60% of the cases); and as MS associated to other anomalies, whether they are other syndromes, disorders, or affectations of other nerves (40%) [2].
