PURPOSE Surgical debridement is the therapy of choice in advanced stages of bisphosphonate-related osteonecrosis of the jaws (BRONJ). However, the therapy is currently only loosely standardized because no suitable imaging modalities exist. This study aims to redress this by exploring the suitability and reproducibility of applying a fluorescence-guided bone(More)
OBJECTIVES Traditional surgical teaching is influenced by restrictive factors, such as financial pressures and ethical constraints. The teaching of surgical skills during a medical school education seems not to be robust enough at present, possibly resulting in stressful circumstance for surgical novices. However, the authors are convinced that practical(More)
Mandibular reconstruction with a fibular free flap has become standard in specialised centres for head and neck reconstruction, particularly for defects with more than one osteotomy that are challenging even for experienced surgeons. Virtual surgical planning is a potential tool to facilitate harvesting of the fibula and the osteostomy. The purpose of this(More)
PURPOSE To date, the therapy of bisphosphonate-associated osteonecrosis of the jaws (BONJ) has been hampered by the lack of imaging modalities that enable the extent of necrosis to be visualized. This study aims to demonstrate the feasibility of tetracycline fluorescence guided bone resection in the surgical management of BONJ. PATIENTS AND METHODS(More)
Despite the refinement of microsurgical techniques, microsurgical free flap transfer in patients with a history of previous radiotherapy, neck dissection or free flaps remains a challenge in oncologic reconstructive surgery. Previous studies on the prognostic factors for postoperative complications have been largely retrospective and shown conflicting(More)
The aim of this study is to evaluate the accuracy of a surgical template-aided implant placement produced by rapid prototyping using a DICOM dataset from cone beam computer tomography (CBCT). On the basis of CBCT scans (Sirona® Galileos), a total of ten models were produced using a rapid-prototyping three-dimensional printer. On the same patients,(More)
Bisphosphonate related osteonecrosis of the jaw (BRONJ) is rare but potentially severe, and the etiopathology and risk factors are poorly defined. To date, it has not been possible to induce BRONJ in a large animal model, a shortfall this study aims to redress. Ten two-year-old adult Göttingen minipigs were split into two groups. Five pigs (group 1) were(More)
A new technique is described that preserves trapezius muscle function in radical neck surgery while cutting that part of the spinal accessory nerve which courses through the sternocleidomastoid muscle. The technique takes advantage of the little-know fact that, in humans, the trapezius muscle has dual innervation. The C2-3-4 motor root is joined to the(More)
PURPOSE Differential diagnosis of osteoradionecrosis and bisphosphonate-related osteonecrosis of the jaw is primarily based on medical history, rather than pathogenesis or histopathology. This report aims to redress this shortcoming by demonstrating the advantages of tetracycline bone fluorescence as an aid to characterize osteonecrosis entities according(More)
