Osteosyntheses of lefort-I fracture.

In mid-face the maxilla represents the bridge between the cranial base superiorly and the dental occlusal plane inferiorly. Its valuable relation with the oral cavity, nasal cavity, and orbits and the multitude of structures contained within and adjacent to it make the maxilla a functionally and cosmetically precise structure. Fracture of these facial bones is potentially life-threatening as well as disfiguring. In time surgical intervention of these fractures provides the best chance to correct deformity and prevent unfavourable sequelae.
