Résumé
Objective To study a safe means of mandibular angle plasty of bone cutting and its clinical efficay.Methods Through grinding bone oblique trapezoidal incisure,mandibular angle wide deformity was then corrected according to the cutting trace on bone cutting method.Results Of 260 cases of torture beauty,185 cases were followed-up,in which 181 (97.84％) cases were satisfied with the results,and 1 case got satisfaction after facial liposuction; other 1 case did not accepted further treatment advice of bone cutting processing because her mandibular angle was too wide.Two cases of bone wax reaction occured and got satisfaction after treatment.Conclusions Mandibular angle plasty by combined grinding with cutting makes it easy for positioning and bone cutting; bone cutting arc becomes more fluent with good exposure of its posterior horn.It can prevent mandibular fracture induced by bone cutting that does not reach the designated position.Therefore,this procedure is relatively simple and safe.
