PURPOSE Autologous, allogenic, and alloplastic materials for bony reconstruction in the craniomaxillofacial region have specific drawbacks stimulating the ongoing search for new materials. Cultivated skin and mucosa grafts are in clinical routine use in head and neck reconstruction but so far, to the best of our knowledge, no successful clinical application(More)
PURPOSE The aim of the present study was to determine the quality of life of patients with respect to pain before, during, and after ablative intraoral tumor surgery. PATIENTS AND METHODS The Bochum Questionnaire on Rehabilitation was used to determine 147 items including the morphologic, functional, and psychosocial aspects of rehabilitation. One(More)
INTRODUCTION Angiogenesis is a cascade-like mechanism which is essential for tumour growth and metastasis. Therefore the existence of angiogenic molecules and the density of activated endothelial cells in individual tumours is of major interest. MATERIAL/PATIENTS: In order to evaluate the prognostic significance of these molecules, the distribution pattern(More)
BACKGROUND Increasing evidence suggests that endoglin (CD105) is a new powerful marker of neovascularization in solid malignancies. To explain the rating of CD105 expression in 51 squamous cell carcinoma of the oral cavity (SCCOC) we analyzed CD105 expression in tumor tissue and adjacent normal healthy mucosa. METHODS Mean CD105 density was quantitated by(More)
Autologous, allogenic and alloplastic materials for bony reconstruction in the cranio-maxillofacial area have many drawbacks thus stimulating the on-going search for new (bio-)materials. Whereas cultivated skin and mucosa are already in clinical routine use in head and neck reconstruction, so far there has been no successful clinical application to the best(More)
In urethra reconstruction, the creation of a new urethra from a free oral mucosa graft is an established surgical technique. The oral mucosa is removed at the same time that the urethra reconstruction procedure is performed. Depending on the size of graft required, the intraoral wound is closed primarily or left to heal secondarily. The latter method limits(More)
In 1984, Glassman et al. described a conservative surgical method of separation of the midpalatal suture in which an osteotomy is done only at the lateral and anterior wall of the maxilla. Between 1991 and 1997, we have operated on 21 patients with maxillary transverse discrepancies using the method that they described. This gave good results in 20(More)
OBJECTIVE We conducted a prospective investigation to evaluate the diagnostic accuracy of computer-aided 3-dimensional (3-D) technetium 99m dicarboxypropane methylene diphosphonate ((99m)Tc-DPD) single photon emission computed tomography (SPECT) reconstruction in the evaluation of microvascular bone flaps used for maxillofacial reconstruction. STUDY(More)
OBJECTIVE A prospective investigation designed to compare the diagnostic accuracy of conventional panoramic and posteroanterior mandibular radiographs with that of coronal computed tomography scans in cases of fracture of the mandibular condylar process was conducted. STUDY DESIGN In all, 182 patients with a total of 249 fractures (some unilateral and(More)
