The present invention relates to a facial mask for the osteogenic distraction of the midface used for the correction of some craniofacial problems, such as depression of the midface, maxillary hypoplasia, asymmetries of the midface and various types of deficiency in craniofacial growth, thus stimulating the bone growth to correct this type of facial malformations. The device consists of a central stem (1) formed by a rod which extends from the top to the bottom of the face of patient, an upper hinge (2) articulating a front support (5) covered by a cushion (6), and a distraction system (22) comprising an upper (22A) and lower (22B) element. The upper element is a flat bolt bent U-shaped upwards at its ends and consisting of a central hinge (18), two lateral supports (24) and an elastic pericranial band (34), placed at both ends and whose purpose is to hold the head and provide stability to the device. The lower element is a bolt, also consisting of a central hinge (18) and two lateral supports (24). The lateral supports of both elements (upper and lower) crosses from front to back by distracting screws (27) wherein wires are inserted that anchored in the inner part of the facial mass for allowing actuating the maxilla or the midface in the direction of the facial mask. Further, an elastic fastener (7) is placed with some links to the intraoral appliance for simultaneously working and facilitating the traction. Finally, it involves a chin guard covered by a cushion (16) for supporting the chin of the patient and being immobilized by an upper stop (10) and a lower stop (12).La presente invención se refiere a una Máscara facial para distracción osteogénica del tercio medio facial que se utiliza para la corrección de algunos problemas craneofaciales como la depresión del tercio medio facial, hipoplasias maxilares, asimetrías del tercio medio y cuya función más propia es su empleo en diversos tipos de deficiencia en el crecimiento craneofacial, estimulando el crecimiento
