In view of orthognathic surgery,on the basis of the ccphalometric data of the youths innorth-west China,the most common 29 parameters were chosen,including angles,linear measureand ratio.For analysis,they were divided into four groups:general profile feature,maxilla andorbital-zygomatic regio,mandible and chin.This kind of analysis can be usecd for clinicaldiagnosis and for detemining the nature,position and degree of the dcformities.It is espceially effec-five in the designing of operation and prediction of the result of the surgery.
