Title: Bimaxillary orthognathic surgery in treatment of dental-facial oblique deformity
Abstract: Objective This paper presents the experiences and techniques of bimaxillary orthognathic surgery in treatment of dental-facial oblique deformities.Methods In past decade,12 patients with dental-facial oblique deformities were treated in this center.The main techniques consisted of Le Fort I osteotomy and sagittal split ramus osteotomy combined with genioplasty.Alternative technique included distraction osteogenesis and rapid prototyping.The patients were divided into 2 groups.beach.according to the ramus procedure performed ether bilaterally or unilaterally.Results The operation and healing were uneventful.During the follow-up for 8 months to 2 years,stable results were found in 9 patients with symmetrical face,normal proportion of facial height,and mouth openning of more than 35 mm.The advantages of computer-assisted mimic surgery and manufacture of implant for hard tissue by rapid prototyping technique are specially presented.Apparent tendency of relapse was found in two cases in group 1 and one case in group 2,which could be controlled by orthodontic treatment.Futher study is needed to correct the deficiency of soft tissue in the face.Conclusions For correction of dental-facial oblique deformity,clinical result can be expected by combination of bimaxillary orthognathic surgery and genioplasy with rapid prototyping technique in future.Further improvement can be expected if the soft tissue can be augmented simultaneously.
