摘      要：Objective Hemifacial microsomia(HFM),a congenital craniofacial malformation,is characterized by unilateral mandibular *** present,the Pruzansky classification is the most common descriptive classification used clinically,which involves mandibular *** multiple classification systems have been proposed for HFM,a quantitative classification has not yet been *** study intended to propose a quantitative classification for HFMaccording to the mandibular volume on the affected *** Patients with HFM from January 2017 to January 2018 were included,and the A/U ratio(volume of the affected side/volume of the unaffected side)was *** study proposed a classification for HFM(mandibular-volume classification,MVC)according to the A/U ratio and compared the new classification system with the Pruzansky classification using consistency and correlation *** A total of 48 patients were *** results of MVC based on the A/U ratio were as follows:A/U0.85,classified asmild;0.73-0.85,as moderate;and0.73 assevere;the weighted kappa value of the Pruzansky and MVC classifications was 0.616(P0.01).Conclusion The quantitative classification of HFMbased on the A/U ratio can serve asa viable evaluation index for patients withHFM and can provide a new reference index for determiningthe treatment plan.
