【Abstract】 Objective To explore the methods of orthognathic treatment for the developmental mandibular asymmetry to simultaneously achieve satisfactory facial appearance and oral functions and to prevent recurrence of the deformity. Methods 37 cases of developmental mandibular asymmetry have been treated in past seven years. The type of the deformity,the management of the cases,and the effects of therapy were summarized in this paper. Results According to the type of the asymmetric deformity,different means were used. After treatment,all the patients obtained satisfactory facial appearance and oral function. Conclusions During the orthognathic treatment,it is important to simultaneously ameliorate facial appearance and achieve good oral function. It should be diagnosed before surgery whether the development of the deformity is steady or not. The correction of skeleton and soft tissues must be performed by stages.更多还原
