title: [Quantitative analysis based on three-dimensional CT in the contouring surgery of craniofacial fibrous dysplasia].
abstract: OBJECTIVE
  To investigate the quantitative analysis based on three-dimensional computed tomography (3D-CT) in contouring surgery of complex craniofacial fibrous dysplasia (FD).
  
  
  METHODS
  14 patients with craniofacial FD underwent 3D-CT scan. Axial images of patients with craniofacial FD were reconstructed into 3D model by using Mimics 10.0. Anatomical landmarks were located and the coordinate of the landmarks obtained. The differences between the right landmarks and the left were calculated and analyzed. Quantitative contouring surgery was performed based on the quantitative analysis result.
  
  
  RESULTS
  With the detail data from the 3D-CT analysis, the surgery of contouring was more safe and accurate with less operation time, less bleeding and good results.
  
  
  CONCLUSIONS
  The method of 3D CT quantitative analysis can provide precise information in the diagnosis and treatment planning of craniofacial deformity. Based on the result of 3D-CT quantitative analysis, the operations can be performed more accurately and safely with good symmetric consequence.
