Purpose: In Venezuela there are few studies that report the epidemiological pattern of Mandibular Fractures.
Materials and methods: The medical records and radiographs for 585 patients treated for mandibular fracture in Caracas, Venezuela, over a 8-year period were reviewed. Variables such as age, gender, etiology, fracture type, treatment techniques, anesthetics and complications. The statistical methodology used was: frequency, percentages, mean, standard deviation, chi-square, t of Student and Fisher.
Results: The male shows was 478 patients (81.7%) and female 107 (18.3%), with a ratio of 4:1. The average age was 28.79 years. The most common range was between 21 to 30 years (38%), followed by 11 to 20 and 31 to 40 with equal numbers of patients, (22.65%) each. Most fractures were caused by physical violence (46.3%), traffic accidents (25.1%), gunshot (17.6%), falls (10.6%) and sporting activities (0,3%). The expressions of physical violence were (44.27%), stroke (41.3%), assault (39.4%) and blunt objects (19.3%). Traffic accidents were (24.78%), automobile (49.0%), motorcycles (35.2%), bicycle (10.3%) and coil (5.5%). As for the location was in body (23.1%), angle (15.6%) condyle (3.9%), symphysis (3.6%), sub-condylar (3.3%), alveolar (3.3%), parasymphysis (2.9%), raw (1.7%) and coronoid (0.3%). The (97.9%) had not complications.
Discussion: Young people are the most susceptible to the mandibular fractures. The violence and traffic accidents are the most frequent etiological factors, and there is a predisposition of women to the falls and men the gunshot. Body and angle are the most fractured, and are more displaced than non-displaced. Post surgical complications were rare.
