title: [Computer-assisted surgery (CAS) for the optimal treatment of craniofacial fibrous dysplasia].
abstract: OBJECTIVE
  The rare bone disease craniofacial fibrous dysplasia is only treated in cases of visible deformities of the splanchnocranium and neurocranium, compression syndromes, and delocation of nasal and paranasal drainage.
  
  
  METHODS
  In a retrospective quality assessment analysis of six patients with craniofacial monostotic fibrous dysplasia, the indications were analysed for situations in which computer-assisted surgery (CAS) might be helpful.
  
  
  CONCLUSIONS
  CAS serves as an intraoperative basis for the assessment of cosmetic-aesthetic corrections of visible bone deformities of the splanchnocranium and neurocranium, and allows the controlled removal of pathologically affected bone in contralateral symmetry. This seems to be important, especially at the anterior skull base, as deformities of the human face produce strong psychological suffering. Furthermore, CAS allows the configuration of implants for defect reconstruction after focal restorations with bony radical surgery. Implants of various material can be prefabricated from these data, which can then be exactly fitted to cover the defect.
