Multi-slice CT imaging in maxillofacial fractures by traffic accident

Abstract

Objectives: study the multi-slice CT (MSCT) imaging in the diagnosis of maxillofacial fractures by traffic accident. Subjects and methods: A cross-sectional descriptive study of 63 patients with maxillofacial trauma due to traffic accidents who underwent MSCT scan at Viet Duc Hospital in April 2022. Results: 46 male and 17 female. The mean age was 28.4±12.6 (from 15 to 75 years old). The most common traffic accidents are motorbikemotorcycle accidents with 21/63 (33.3%), self-motorbike-riding accidents are 18/63 (28.6%), car-motorcycle accidents account for 16 /63 (25.4%), pedestrian - car/motorcycle accidents are 5/63 (7.9%) and car-car accidents are 3/63 (4.8%). There were 28/63 (44.4%) cases associated with cranial fracture and 32/63 (50.8%) skull base fracture. In cases of maxillofacial fracture, orbital wall fracture was the most common with 41/63 (65.1%), maxillary fracture 39/63 (61.9%), zygomatic fracture 32/63 (50.8%), nose bone 19/63 (30.2%), frontal sinus wall 13/63 (20.6%), palatal and mandibular fracture were 11/6 (17.5%). The most common type of maxillary fractures is Lefort 1 with 11/63 (17, 5%) on both right and left side, Lefort 2 and 3 fractures are less common with 1.6% to 6.3%, respectively. Conclusion: MSCT is a reliable method in diagnosing maxillofacial fractures.
