Use of the orthognathic surgery simulating instrument in the presurgical evaluation of facial asymmetry.
The use of Orthognathic Surgery Simulating Instrument (OSSI) is described. Two cases of facial asymmetry, one with hemifacial microsomia and one with unilateral condylar hyperplasia, are presented to demonstrate the diagnostic capabilities of the articulator. The OSSI has greatly improved our ability to plan the treatment of cases of gross facial asymmetry.
