RIBEIRO, Felipe Friedrich et al. Study of prevalence of mandibular fractures in Joinville-SC. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2012, vol.12, n.3, pp. 79-84. ISSN 1808-5210.

The aim of this study was to evaluate the prevalence of mandibular fractures treated at the São José in Joinville Municipal Hospital over a period of 18 months. A total of 83 fractures in 52 patients with mandibular fractures was recorded. The results showed a greater frequency of fractures of the jaw in males (45 cases); the 21 to 30-yr age group was the most affected; and automobile accidents (22 cases) were the most common cause, followed by physical aggression (19 cases). Forty-two patients had isolated jaw fractures and 10 also had other associated facial fractures. Thirty-seven cases were treated merely by open reduction and rigid internal fixation with the use of miniplates and the other 15 by maxillomandibular fixation. The most prevalent types of jaw fractures were those of the mandibular angle, the mandibular body and symphysis, with 21 cases, 16 in the condylar region and four in the ramus.
