MEDINA, María Jesús et al. Maxillofacial Fractures in Chilean Subjects. Int. J. Morphol. [online]. 2006, vol.24, n.3, pp.423-428. ISSN 0717-9502.

The oral and maxillofacial trauma represent a 6% to 8% approximately of the body fractures. These injuries are of complex handling and demand an accurate and precise diagnosis. The Hernán Henríquez Aravena Regional Hospital, of Temuco city, does not have oral and maxillofacial surgeons in the immediate urgency staff, so that first approach to handle those patients is made by other clinicians. After one year, a total of 34,931 consultations were made in the Urgency Service at the Hernán Henríquez Aravena Hospital. Of them, a representative sample of 742 subjects was chosen from which general information and the kind of injuries was obtained. Statistical association with the Chi - Square test was obtained. Six percent of the consultations in the Hernán Henríquez Aravena Regional Hospital were associated to maxillofacial fractures. 64.4% of the sample corresponded to male subjects. The relation man to woman was 3.1:1, displaying a greater difference in patients aged over 15 years. Of the total of sample, the group with more consultations was those aged below 20 years and the 31,1% of the consultations were caused by aggressions, whereas 24,4% were associated to falls. The main zone of fracture was related to the orbit nose etmoidal complex with 55,6% and dental fractures with a 22.2%. Statistically significance association was found between age, sex, aggression, mandible and dental fractures (p < 0,05) The data reflect the high prevalence of maxillofacial fractures in Temuco, Chile, similar to other parts of the world. The group of young people is the one of main consultation where the aggressions play a fundamental roll. With the present descriptive study we think that the presence of oral and maxillofacial surgeons in the urgency staff of the Hernán Henríquez Aravena Regional Hospital, Temuco, Chile is justified totally
