BACKGROUND The most frequently performed osteotomy for correction of mandibular retrognathia is a bilateral sagittal split ramus osteotomy. Permanent neurosensory disturbance of the inferior alveolar nerve is one of the most frequently and severe complications. Many authors have reported this, but the incidence differs widely. In the recent literature, only four authors have reported a percenta...

BACKGROUND Although percutaneous posterior-ring tension-band metallic plate and percutaneous iliosacral screws are used to fix unstable posterior pelvic ring fractures, the biomechanical stability and compatibility of both internal fixation techniques for the treatment of Denis I, II and III type vertical sacral fractures remain unclear. METHODS Using CT and MR images of the second generation...

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...

Purpose: The purpose of this study was to assess skeletal stability after mandibular setback surgery with and without an inter-maxillary fixation (IMF) screw. Subjects and Methods: The subjects consisted of 40 patients with mandibular prognathism. The subjects underwent sagittal split ramus osteotomy (SSRO) with titanium plate fixation and were divided into two groups, one with and one without ...

Introduction: The primary concern in the placement of ramal bone screws is blind nature procedure, as there a thick, mobile layer soft tissue over bone; also, ramus not uniplanar structure but swerving like propeller blade. purpose this study was to evaluate possibility establishing clinical guidelines based on visible dental and soft-tissue landmarks for safe, reliable, accurate insertion scre...

BACKGROUND The aim of the present study was to evaluate the treatment of patients developing a transverse jaw width discrepancy who exhibited class III malocclusion and/or facial asymmetry by a combination of mandibular constriction (MC) and intraoral vertical ramus osteotomies (IVROs). SUBJECTS AND METHODS In a retrospective study, functional results, postoperative complications, and skeleta...

PURPOSE To analyze the effectiveness of anterior pelvic plating and subsequent percutaneous sacroiliac joint screw fixation in patients with unstable pelvic ring injuries. MATERIALS AND METHODS Thirty-two patients were included with twenty-one males and eleven females. The mean age was 41 years (range, 19-76). The mean follow-up period was 51 months (range, 36-73). According to AO-OTA classif...
