[Relationship between injury dynamics and site of maxillofacial fractures. Comparative study of 100 cases].

One hundred cases of facial mass fractures observed in the period April-September 1988 have been assessed using a clinico-anamnestic type investigation. Among trauma patients there is a prevalence of male patients aged between 10 and 30. Fractures located at the middle third and mandible occur in a practically equivalent number. Most traumas are the result of road accidents, following by falls. A good degree of correlation was observed between trauma aetiology and dynamics on the one hand and type and gravity of fractures on the other. Direct fractures, with greatest comminution of fragments prevail in high speed traumas; indirect fractures are most frequent in low speed traumas (cyclists and accidental).
