Objective The aim of this study is to quantitatively evaluate the stability of the skeletal and dental widths using cone-beam computed tomography (CBCT) after segmental Le Fort I osteotomy in adult patients with skeletal Class III malocclusion requiring maxillary expansion. Methods In total, 25 and 36 patients with skeletal Class III malocclusion underwent Le Fort I osteotomy (control group) ...

OBJECTIVE The purpose of this study was to evaluate the horizontal changes in the condylar head with bent plate fixation after sagittal split ramus osteotomy (SSRO) with and without a Le Fort I osteotomy. STUDY DESIGN Of 47 Japanese patients with mandibular prognathism, 24 underwent SSRO and 23 underwent SSRO in combination with a Le Fort I osteotomy. A 3-5-mm gap was made between the proxima...

BACKGROUND Patients undergoing orthognathic procedures can require blood transfusions. The objectives of this study were to evaluate the predictors of intra-operative blood loss in patients undergoing orthognathic procedures and the transfusion rates and practices of our institution. MATERIALS AND METHODS This retrospective study included 92 patients who underwent the following four types of ...

BACKGROUND The amount of postoperative maxillary relapse of two different bone graft materials after Le Fort I osteotomy were compared in this study. OBJECTIVES The aim of this study is to compare postoperative maxillary relapse rates using heterologous and autologous graft materials after Le Fort I osteotomy. MATERIAL AND METHODS A total of 80 patients who had developmental malocclusion we...

OBJECTIVE Abnormalities of the midface and maxilla are frequently corrected using Le Fort I surgery. This osteotomy passes near the apices of the maxillary teeth, severing the blood vessels and nerves supplying the teeth. The aim of this review was to determine the effect of Le Fort I osteotomy on pulpal vascularity and neurosensory response. DATA SOURCES A systematic search of the literature...

Background. The combination of Dega transililiac and femoral subtrochanteric is used in our department in the treatment of Legg-Calvé-Perthes' disease. Subtrochanteric osteotomy, initially performed as varus-derotation osteotomy, is now mainly extension osteotomy with shortening. Femoral shortening is crucial for joint decompression and makes room for pelvic redirection after pelvic osteotomy. ...

PURPOSE Plantarmedial release and first ray extension osteotomy are often combined to treat paralytic cavovarus foot deformity. The purpose of this study is to evaluate the effect of additional first ray extension osteotomy in terms of dynamic pedobarography. MATERIALS AND METHODS We reviewed findings of pre- and postoperative plain radiography and dynamic pedobarography for 25 patients in wh...

OBJECTIVE Distraction osteogenesis is a well-accepted technique in the treatment of patients with hypoplastic craniofacial components. Complications of distraction osteogenesis are well described in the literature. We describe a complication of using an external distraction device in a 9-year-old girl with Pfeiffer. INTERVENTION AND RESULTS A modified Lefort III osteotomy was performed for ma...
