RÉSUMÉ
The aim of this study was to emphasize the role of 2nd and 3rd reconstruction in the evaluation of the maxillofacial lesions. This was performed on 50 patients classified into 5 groups; congenital maxillofacial lesions [10 patients], maxillofacial fractures [23 patients], inflammatory lesions [6 patients], neoplastic lesions [5 patients] and temporo-mandibular joint disorders [6 patients]. It was concluded that 3D reconstruction complements 2D CT scanning, which may be valuable in preoperative ii assessments of maxillofacial lesions. 3D CT reformation was an available adjunct in the evaluation of congenital maxillofacial anomalies, as it was able to demonstrate the precise osseous anatomy and offered a simplified technique for viewing and interpreting facial. 3D CT gave good visualization of the extent and course of fracture lines. 3D CT showed better visualization of the destructive bony processes in neoplastic masses, while, the delineation of soft tissue masses was better appreciated on conventional CT images
