PURPOSE To classify muscle fibers of human extraocular muscle (hEOM) and to compare them to previous studies on hEOM, as well as to nonhuman EOM classification schemes and skeletal muscle fiber types. METHODS Muscle fibers cut in different muscle planes were followed on consecutive cross sections and typed with regard to their oxidative profile in(More)
In the present study, two biphasic calcium phosphate biomaterials (BCP) with HA/TCP ratios of 50/50 and 30/70 were obtained from a pure HA biomaterial. The biomaterials which showed the same three-dimensional geometry were implanted into corticocancellous costal defects of sheep. In the specimens of all three biomaterials, abundant bone formation, mineral(More)
Apart from the somatotopic organization of the trigeminal ganglion (TG) into the ophthalmic, maxillary and mandibular divisions along the mediolateral axis, there exist further somatotopic organizations within these three divisions. According to literature, the cell organization in the TG and the somatotopy in the brainstem develop together, formed by(More)
PURPOSE The present study was conducted to evaluate the effect of platelet-rich plasma (PRP) on new bone formation and remodeling after grafting of the maxillary sinus with an algae-derived hydroxyapatite AlgOss/C Graft/Algipore. MATERIALS AND METHODS Fourteen consecutive patients with severely atrophic maxillae underwent uni- or bilateral grafting of the(More)
The present study investigated the hypothesis that hydroxyapatite (HA), tricalcium phosphate (TCP), and a HA-gel coated on endosseous titanium (Ti) implants by spark discharging (SD) and dip coating would achieve predictable osseointegration without evident bioresorption of the coatings on the long term. A costal sheep model was used for the implantation of(More)
The clinical outcome of two stage reconstruction with revascularized grafts after resection of extensive retromolar and oropharyngeal squamous cell carcinoma in 17 patients is presented. In the first operation, the intraoral soft tissue defect was covered by a revascularized jejunal flap, and the mandibular defect was bridged by a reconstruction plate.(More)
In the present work two methods of harvesting the RFFF (radial free forearm flap) are compared: the prelaminated fasciomucosal and the non-prelaminated fasciocutaneous version. The flaps were employed for intraoral reconstruction after radical oncological surgery of the oral cavity. In most cases a squamous cell carcinoma was the present malignant tumour. A(More)
