Intraoperative measurement of maxillary repositioning: an ancillary technique.
A technique for measuring maxillary movement with the LeFort I osteotomy is described. Three-dimensional measurement of upper jaw position can be gauged to within 1 mm by means of a simple two-point measurement system. When used in combination with direct bone measurements and appropriate surgical sequencing, assessment of maxillary repositioning is possible at virtually any time during the surgical procedure.
