title: Radiological assessment of hemifacial microsomia by three-dimensional computed tomography.
abstract: Hemifacial microsomia (HFM) is the commonest asymmetrical craniofacial deformity leading to underdevelopment of the craniofacial skeleton and soft tissues on the affected side. Timing of reconstructive surgery is based on a comprehensive analysis and classification of the deformity. Lateral cephalometric radiographs are of limited value because of superimposition of normal and abnormal bony structures. The skeletal and soft-tissue findings of six patients with HFM who underwent three-dimensional (3D) CT are presented. This method allows a comprehensive assessment of the deformity at a low radiation dose, 22% of that of a conventional CT scan, by the use of a low dose technique.
