Abstract

Introduction: The clinical and paraclinical symptoms of Le Fort II maxillary fractures are quite diverse and play a crucial role in guiding surgical treatment. Objectives: To describe the clinical features, radiographic (X-ray) images, and computed tomography (CT) scans of patients with Le Fort II maxillary fractures. Materials and Methods: A cross-sectional descriptive study was conducted on 35 Le Fort II maxillary fracture patients who underwent surgical treatment at Can Tho Central General Hospital from June 2023 to December 2024. Results: The average age of the patients was 32.4±13.21 years, with the majority in the 19-39 age group (65.7%) and predominantly male (82.9%). All patients (100%) presented with bone discontinuity or step defects, tenderness at specific pressure points, and abnormal mobility of the maxilla. Clinical symptoms included facial deformity (82.9%), restricted mouth opening (82.9%), and malocclusion (94.3%). X-ray and CT scans (including 3D reconstruction) revealed that the fracture line predominantly passed through the zygomaticomaxillary suture with corresponding rates of 94.2% and 94.3% on the right side and 91.2% and 94.3% on the left side. Conclusion: Le Fort II maxillary fractures primarily occur in males aged 19-39. Clinical, X-ray, and CT image findings are diverse, with fracture lines most commonly passing through the zygomaticomaxillary suture in over 91.2% of cases.
