RESUMO
Maxillofacial trauma is associated with facial deformation, loss of function, emotional and social impacts, and high financial costs. This study investigated cases of maxillofacial trauma in a large Brazilian city through a cross-sectional study conducted at two public and two private hospitals. Primary data of 400 patients were collected through a questionnaire, clinical examination, and tomography. Statistical analysis at the 5% significance level was performed. Motorcycle accident was the major cause of trauma (41%); the most frequent trauma and treatment were mandibular fracture (24.3%) and surgery (71%), respectively. The female sex was more affected only regarding domestic accidents (p = 0.041) and falls (p < 0.001). Motorcycle accidents were more prevalent among 20 to 29 year-olds (p < 0.001), followed by physical aggression (p < 0.001) and sports accidents (p = 0.004). Falls were more frequent among 40 to 59 year-olds (p < 0.001). Mandibular fracture affected males and 20 to 29 year-olds more and was mainly associated with motorcycle accidents (48.2%) and physical aggression (22.7%) (p = 0.008). Nose fracture was more frequent in falls (29.6%), physical aggression (22.5%), and sports accidents (21.1%) (p < 0.001). Compound fracture was associated with motorcycle accidents (84.2%; p = 0.028). Maxillofacial trauma (mandibular, nasal, and zygomatic fractures) was associated with motorcycle accidents, physical aggression, and falls. Surgical treatment, hospital care, and public services were the most frequent.
