Ossified ligamentum flavum (OLF) is a condition of heterotopic lamellar bone formation within the yellow ligament. Some patients with OLF can be asymptomatic. However, asymptomatic OLF may not be obvious on preoperative MRI and could increase the risk of iatrogenic injury during treatments for unrelated spinal conditions. This report describes a case of spinal cord injury caused by the indirect...

A systematic literature review and a meta-analysis of indirect sinus lift without the use of bone graft material was performed. A PubMed search was made from January 2005 to January 2012 with keywords: "sinus lift", "osteotome", "graft" and "maxillary sinus elevation". The inclusion criteria were: maxillary sinus lift technique with osteotomes with a minimum follow-up period of 5 months after s...

the aim of this study was to compare the lateral window and osteotome techniques for sinus lifting using histological and histomorphometric methods.in this clinical trial 10 patients (a total number of 14 sinus areas) who needed implant treatment in the atrophic posterior maxilla were enrolled. in all the cases the residual bone height between the sinus floor and the alveolar crest was less tha...

Since maxillofacial injury is frequently accompanied by other diseases, its evaluation and treatment are open delayed. When the evaluation is delayed, the surgical treatment can be difficult or impossible. A 21-yr-old man presented with right facial swelling and deformity after injury. We planned immediate surgical repair for his right tetrapod fracture, but the operation was delayed for two mo...

AIM The aim of the study was to evaluate retrospectively maxillary sinus functions and complications by using generally accepted diagnostic criteria with lateral window and osteotome sinus floor elevation (OSFE) procedures followed by dental implants placement. MATERIALS AND METHODS A group of 60 patients in whom a SFE with the two procedures (lateral window and OSFE) followed by dental impla...

_Since its introduction, sinus floor augmentation has generated great interest in the international scientific community and been subject to many changes in procedure. The first documented maxillary sinus augmentations using bone grafts date back to the work of Philip J. Boyne in the 1960s.1 An access osteotomy to elevate the sinus membrane can be performed by a vestibular or a crestal approach...
