Malar bones play an important role in facial form and are one of the surrounding bony structures of the orbit. If they are displaced and not correctly treated. They will cause disfigurement and also severe disability due to interference with vision or mastication. Up to now there are many classification of the Malar bone fractures. So the determination of the most practicable one to be applied in Vietnam will be very necessary for the prognosis and treatment

A retrospective study on 2149 patients with the maxillo facial fracture in the Institute of facio-maxillodentology during 1988- 1998 has shown that the morbidity rate in men was higher than this in women. The patients with ages of 20 -40 accounted for 65%. 40% of patients were at ages of 20 -29. The mandibular fracture accounted for 64%. The treatment mainly involved the reconstruction and the bone cooperation by steel thread with the good results (85.3%).

Zygomaticomaxillary fractures (ZMF) often have characteristic clinical signs as well as the functional signs, such as difficult in opening of the mouth, occular movement and bad influence on aesthetics. In case of therapy it was very important to choose the best way of topographic analytic severity and direction of bone- displacement in of ZMF, all this aims at the selection of the most suitable therapeutical procedure. This written assessment aims at highlighting the most characteristic clinical signs and various therapeutic methods frequently used in 157 patients with ZMF.
