[The orthognathic treatment of mandibular asymmetry].

OBJECTIVE

To evaluate the methods of orthognathic treatment for mandibular asymmetry.

METHODS

110 cases of mandibular asymmetry had been treated in past thirteen years. The type of deformity, the management of the cases, and the effects of orthognathic treatment were summarized in this paper. Orthodontic therapy was taken before and after operation to keep the treatment effect.

RESULTS

According to the type of the asymmetry deformity, different methods were used. After treatment, all the patients obtained satisfactory facial appearances and oral function.

CONCLUSION

It should be diagnosed before surgery whether the development of deformity is steady or not. If it is steady, the effects of orthognathic and orthodontic therapy will be satisfactory; if not, we should remove the affected condyles and simulataneously ameliorate facial appearance.
