[A statistical contribution to fractures of the maxillofacial area]

Twenty years experience (from 1975 to 1994), on 483 patients with injury of the maxillo-facial area observed at the Department of Maxillo-Facial Surgery of the University of Naples "Federico II" is reported. The analysis of the data, according to the literature, shows that the sex most involved is male (76%) with a prevalence of the second decade of life (38%); street injury is the most frequent cause of maxillo-facial fracture (48.5%), while in 1.6% the cause is not reported. Mandibular fractures (57%), particularly those of the left condyle, are more frequent. The type of treatment is discussed in relation to the site of fracture, in particular the therapy of the condylar ones. In fact, in the treatment of those fractures the authors use sequential functional plates, the first of whose presents a monolateral byte, homolateral to the injury, while the second a contralateral guide in closure. The use of such plates, even if it doesn't often obtain a perfect anatomical realignment of the fracture, allows an optimal functional rehabilitation due to the potential of remodelling of the condyle, avoiding complications related to surgical intervention.
