| Abstract: | OBJECTIVE: To evaluate the usefulness of two- dimensional (2D) and three-dimensional (3D) computed tomography (CT) in the identification and classification of Le Fort type fractures. METHODS: Sixty-two patients with different types of Le Fort fractures underwent CT scanning and 3D-CT reconstruction. The data were analyzed by multiplanar reconstruction (MPR), surface shaded display (SSD) and volume rendering (VR) respectively. RESULTS: The patients with Le Fort I, Le Fort II fracture and Le Fort III fracture accounted for 16.1%, 14.5% and 12.9% respectively. The compound fractures were the most common type and accounted for 56.5% (n=35, 18 cases with Le Fort I+II fracture, 10 cases with Le Fort II+III fracture and 7 cases with Le Fort I+ II+III fracture). Fifty-five cases coexisted with other fractures in maxillofacial region. 2D-CT could be used to define the tiny fractures and the deep-structure fractures more accurately compared with 3D-CT, but the real impression of Le Fort type fractures could not be correctly evaluated on 2D-CT. 3D-CT could clearly demonstrate the whole shape of Le Fort type fractures and identify the classification of Le Fort fractures. CONCLUSIONS: 3D-CT is the best imaging method for the diagnosis of Le Fort type fractures and can provide valuable information of space relationship, especially for the design of treatment plan before operation. |
