Mandibulo-facial dysostosis. Analysis; principles of surgery.

Before regarding the treatment of facial deformities in mandibulo-facial dysostosis, the clinical, radiological and anatomical findings are reviewed. The plastic surgical correction of the main deformities are then considered. The aims of the treatment are: close the palpebral coloboma, build the zygomatic bones and zygomatic arches, correct the malformation of the auricles and the macrostomia, re-establish normal dental occlusion if necessary and harmonize the profile by reducing the nose and excessive vertical dimension of the mental symphysis.
