OBJECTIVES To assess the prevalence of speech and swallowing impairment after radical surgery for oral and oropharyngeal cancer from the patient's viewpoint and to examine the association of these functional alterations with selected clinical characteristics regarding patients, tumors, and oncologic treatment. DESIGN Cross-sectional, multicenter study(More)
PURPOSE To evaluate current trends in maxillofacial trauma, a retrospective review of mandibular fractures at a German university hospital was carried out. PATIENTS AND METHODS In this retrospective study, records of 444 patients with mandibular fractures between 2000 and 2005 at the Department of Oral and Maxillofacial Surgery, University Hospital of(More)
OBJECTIVES Minor sinus floor elevation is a method with relatively high predictability but is technically demanding. Improvement of the technique and increase in the predictability are desirable. MATERIAL AND METHODS A clinical protocol for minor sinus floor elevation with SLA-ITI (large grit acid-etched implants with diameter of 4.8 mm) is described.(More)
For the treatment of bisphosphonate-associated osteonecrosis of the jaw (BP-associated ONJ), poor cure rates are reported. In many cases, repeated osseous exposition and infection may occur. The currently recommended management of affected patients is antibiotic treatment and bony decortication, which is often complicated by soft tissue deficits due to(More)
BACKGROUND Squamous cell carcinoma mainly afflicts patients older than 40 years of age however, few cases are seen in younger patients. The aim of this study therefore was to determine the incidence of squamous cell carcinoma of the oral cavity and oropharynx in patients less than 40 years of age with a view to assessing the prognosis over a period of time.(More)
PURPOSE Manual segmentation of CT datasets for preoperative planning and intraoperative navigation is a time-consuming procedure. The purpose of this study was to develop an automated segmentation procedure for the facial skeleton based on a virtual anatomic atlas of the skull, to test its practicability, and to evaluate the accuracy of the segmented(More)
BACKGROUND The aim of orbital wall reconstruction is to reestablish anatomically exact orbital volumes to avoid long-term complications. Navigation could facilitate complex reconstructions. METHODS Quality of the orbital reconstruction (n=94) was measured based on (A) volume changes and (B) on 3D shape deviations compared to the unaffected side. Volume(More)
Ablative tumor surgery and orbital and midface reconstruction, as much as orthognathic surgery, requires detailed planning using computed tomography (CT) or magnetic resonance imaging (MRI). These techniques also allow simulation of complex surgeries preoperatively. Proper reconstruction depends on reliable information to choose the correct type of grafts(More)
OBJECTIVES Reconstruction of large mandiblular defects following ablative oncologic surgery could be done by using vascularized bone transfer or, more often, primarily with simultaneous or delayed bone grafting, using load bearing reconstruction plates. Bending of these reconstruction plates is typically directed along the outer contour of the original(More)
For tissue engineering, scaffolds should be biocompatible and promote neovascularization. Because little is known on those specific properties, we herein studied in vivo the host angiogenic and inflammatory response after implantation of commonly used scaffold materials. Porous poly(L-lactide-co-glycolide) (PLGA) and collagen-chitosan-hydroxyapatite(More)
