OBJECTIVE The purpose of this retrospective study was to evaluate complications before, during, and after vertical alveolar distraction osteogenesis and to assess the survival rate of dental implants placed in distracted bone. STUDY DESIGN In a consecutive series, 37 patients with 45 alveolar ridge deficiencies of the partially edentulous mandible were(More)
OBJECTIVE The purpose of this retrospective study was to identify the major pathogens responsible for deep space head and neck infections and their current resistance to routinely used antibiotics in a university hospital setting. STUDY DESIGN A total of 206 patients suffering from odontogenic deep space infections were treated at our department by means(More)
INTRODUCTION The aim of this study was to review survival and locoregional control in patients with advanced oral and oropharyngeal squamous cell carcinoma treated by multimodal therapy with preoperative radiochemotherapy and radical surgery. MATERIAL Retrospective cohort study. METHODS Included in this analysis are 276 consecutive patients with UICC(More)
PURPOSE This retrospective study was performed to present our long-term results in the treatment of maxillary squamous cell carcinoma and evaluate especially the influence of T staging and grading on patients' survival. PATIENTS AND METHODS We performed a retrospective analysis of 93 consecutive patients with alveolar, gingival, or palatal maxillary SCC(More)
PURPOSE To evaluate the feasibility and accuracy of a new method for planning and realizing zygomatic osteotomies in cases of established post-traumatic deformities using stereolithographic (SL) models and computer assisted navigation. PATIENTS AND METHODS In 5 patients, osteotomy and repositioning of the zygomatic complex was planned using SL models. The(More)
The purpose of this study was to assess the prognostic value of histological response to preoperative radiochemotherapy in an established multimodal therapy concept for advanced oral and oropharyngeal cancer. Two hundred and twenty-two patients who underwent preoperative radiochemotherapy (RCT: 50 Gy, mitomycin C and fluorouracil) and radical surgery were(More)
OBJECTIVES The aim was to investigate the image quality of dual-energy computed-tomography (DECT) compared to single-energy images at 80 kV and 140 kV in oral tumors. MATERIALS AND METHODS Forty patients underwent a contrast-enhanced DECT scan on a definition flash-CT. Four reconstructions (80 kV, 140 kV, mixed (M), and optimum-contrast (OC)) were(More)
INTRODUCTION Multi-modality treatment concepts involving preoperative radiotherapy (RT) or chemoradiotherapy (CRT) and subsequent radical resection are used much less frequently than postoperative treatment for oral and oropharyngeal squamous cell carcinomas. In some centres, however, the preoperative approach has been established for several years. (More)
INTRODUCTION Lymphoscintigraphic planar imaging is a common procedure for sentinel lymph node imaging prior to lymph node biopsy, but fails to elucidate the specific lymphatic drainage. Composite functional/anatomical imaging (SPECT-CT) has the potential to enhance topographic orientation and diagnostic sensitivity of sentinel lymph node imaging, but has(More)
PURPOSE In this retrospective study, we evaluated isolated blowout fractures of the orbital floor by region-of-interest measurements from coronal computed tomography (CT) scans and their relationship to ophthalmologic findings. PATIENTS AND METHODS Fracture area and volume of displaced tissue of blowout fractures in 38 patients were measured from coronal(More)
