title: [Precision of computer-assisted systems in profile reconstructive interventions on the face].
abstract: In this investigation we compared the precision of different computer-aided systems for positioning osteotomized segments to reconstruct craniofacial asymmetries. The accuracy of a mechanical navigation system, a laser-guided navigation system and the precision of templates moulded on stereolithographic models are compared, using measurements on geometrical objects, anatomical specimens and clinical application. The precision of a mechanical navigation system is 0.5 mm, and a laser-guided system 0.3 mm. The accuracy of a computer and template guided application is 1 mm.
