Sagittal split osteotomy (SSO) is a surgical technique largely employed for mandibular mobilizations in orthognatic procedures. However, the traditional design of buccal osteotomy, located at the junction of mandibular ramus and body, may prevent more extensive sliding between the bone segments, particularly on the advance, laterality and verticality of the mandibular body. The author proposes ...

Percutaneous screw insertion for minimally displaced or reducible acetabular fracture using x-ray fluoroscopy and computer-assisted navigation system has been advocated by some authors. The purpose of this study was to compare intraoperative conditions and clinical results between isocentric C-arm 3-dimensional (Iso-C 3D) fluoroscopy and conventional fluoroscopy for percutaneous retrograde scre...

Case RepoRt A 55-year-old male patient signed in for replacement of his edentulous space by implants. Most of his maxillary and mandibular teeth had got exfoliated because of periodontitis and the patient was edentulous for around 8-10 years. He had now visited us for replacement of teeth. A panoramic radiograph was made in which showed as an incidental finding of multiple bilateral radiopacite...

UNLABELLED Among the osteotomies performed in orthognathic surgery, the sagittal osteotomy of the mandibular ramus (SOMR) is the most common, allowing a great range of movements and stable internal fixation (SIF), therefore eliminating the need of maxillomandibular block in the postoperative period. OBJECTIVES The purpose of this study was to evaluate the biomechanical resistance of three nat...

The aim of this study was to determine the influence of the design of the sagittal split ramus osteotomy (SSRO) on the mechanical resistance to vertical forces. An in vitro study was designed for 30 test specimens. Two osteotomy models were made on two polyurethane hemimandibles, where group I presented a SSRO with an angle at vestibular level between both molars and group II presented a linear...

The standard surgical treatment for mandibular prognathism is sagittal split ramus osteotomy (SSRO) if the proximal and distal segments of the ramus require fixing with screws or metal plates. In this procedure, however, it is frequently difficult to avoid neurosensory disturbance (NSD) of the inferior alveolar nerve (IAN) when the posterior margin of the ramus curves inward or when the ramus i...

OBJECTIVE This study evaluated the mechanical characteristics and stress distribution of the hybrid technique fixation of the sagittal split ramus osteotomy. STUDY DESIGN In the mechanical test, 10 polyurethane replicas of human hemimandibles of each group were submitted to linear loading test. For the photoelastic evaluation, 3 hemimandible replicas of photoelastic resin were subjected to ph...

Abstract Funding Acknowledgements Type of funding sources: None. Background The ramus artery contributes to the development turbulence, which may influence computed tomography (CT) derived fractional flow reserve (FFRCT) even without coronary disease. relationship between ramus-induced turbulence and FFRCT is unclear. Purpose To investigate effect on in normal arteries. Methods A total 120 cons...

We treated 39 patients with fractures of the humeral shaft by closed retrograde locked intramedullary nailing, using Russell-Taylor humeral nails. The mean healing time of all fractures was 13.7 weeks. After consolidation, shoulder function was excellent in 92.3% and elbow function excellent in 87.2%. Functional end-results were excellent in 84.6% of patients, moderate in 10.3% and bad in 5.1%....

In addition to the benefit of open surgical treatment of the scaphoid, a reduced downtime and a rapid return to work, percutaneous screw technique also reduces operative risks, avoids the possibility of soft tissue collapsing, the devascularisation of the fracture site and therefore is associated with lower risks of nonunion. The authors report the case of a 27-year-old patient, receiving surgi...
