title: Computer-assisted mandibular condyle positioning in orthognathic surgery.
abstract: OBJECTIVE
  The correct placement of the mandibular condyle in the glenoid fossa during the osteosynthesis after the sagittal ramus osteotomy is often a problem. This article describes a computer-assisted positioning device.
  
  
  METHODS
  The procedure is based on the use of a three-dimensional optical localizer to establish the condylar segment position. The operative procedure is only slightly different from the usual.
  
  
  RESULTS
  The system is very easy to use, it does not require preoperative data acquisition, and the accuracy obtained is in fractions of a millimeter.
