【Abstract】 Cephalometric analysis has been a very important method for maxillofacial sur- geon and orthodontist in the diagnosls,treatment planning and result evaluationof patients with dentofacial deformities.Although there are some cephalometricappraisals in China,we had no cephalometric standards for the local Chinese inChengdu with which we could compare or assess the patients who came to us fortreatment.There is an urgent need to establish standards for the Chinese in Ch-engdu is evident,it is the main purpose of this study.This study consists of three parts:(1)Skeletal measurements(2)Dental mea-surements(3)Soft tissue measurements.There are 38 parameters(16angles,22 ti-nes)in this study.In order to assess the change of the position of maxilla preope-ratively and postoperatively,we measure angle SNP which has not been measuredby other investigators.In order to assess the positional change of maxillary andmandibular plans,we used FH and SN plans simultaneously and measure angle SN—FH,SN—MP,PP—MP,FH—MP.Maxillofacial surgeons usually pay great atten-tion to the amount of maxillary and mandibular movement,and therefore wemeasure NP—A(mm),NP—B(mm),NP—PG(mm)for clinical analysis and compari-son.Soft tissue is very important to facial appearance,therefore we measure theintegumental extension in millimeters and profile,facial soft tissue angles.we think,the quadrilateral analysis is necessary in some patients.更多还原
