title: Le Fort fractures (I). A study of frequency, etiology and treatment.
abstract: The cause and frequency of maxillary fractures as well as type of treatment performed has been reviewed in this study. During the time period between 1969 and 1982, a total of 301 maxillary fractures have been treated at our Department of Oral and Maxillofacial Surgery in Gothenburg. The period has been subdivided in 3 parts to evaluate whether differences in the amount of severe fractures could be observed. Since a law was instituted in Sweden in 1975 calling for a mandatory use of front seat belts, the frequency of fractures related to the time periods before and after 1975 could be of interest. We found a surprisingly equal number of fracture incidents during the different periods of time, but a decreasing number of maxillary fractures of type le Fort I, II and III; partial maxillary fractures on the other hand, had increased in number.
