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)
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)
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)
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)
PURPOSE Vertical osteodistraction is a new alternative method for alveolar ridge augmentation of the mandible. The purpose of this article is describe a technique using an L-shaped osteotomy and titanium membranes for guided bone regeneration (GBR) in the distraction gap. PATIENTS AND METHODS Ten patients with severe atrophy of the edentulous molar region(More)
PURPOSE To perform a systematic review of the published data concerning maxillomandibular advancement for the treatment of obstructive sleep apnea syndrome. MATERIALS AND METHODS A systematic literature search was performed in the PubMed database. Original articles in the English language were reviewed to obtain information about patient data, success(More)
PURPOSE A computer program recently developed for the calculation of the orbital floor and fracture areas from coronal computed tomography (CT) scans was used in a study to evaluate the accuracy and ability of this new method. MATERIAL AND METHODS The size of orbital floors and fabricated fractures in 14 dried, anatomic specimens were measured in coronal(More)
PURPOSE The aim of this study was to analyze the 3-dimensional movement of the mandible segments after distraction of the mandibular midline by use of a cemented and screw-fixated tooth-borne appliance. PATIENTS AND METHODS Twenty patients with transverse deficiencies of the lower arch were included in a consecutive study. Before surgical intervention, a(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)
