  2. 1. Skull base meningioma : Surgical and adjuvant treatment with clinical and PET evaluation

    Author : Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Meningioma; cerebellopontine angle; translabyrinthine and transcochlear approaches; facial nerve; steretactic irradiation; proton beam therapy; interferon- alpha; PET; 11C-L-methionine; 76BR-BrdU; Neurovetenskap; Neurology; Neurologi; Medicine; medicin;

    Abstract : The treatment strategy for skull base meningiomas remains a controversial issue. Because of the proximity of these tumours to critical neurovascular structures, the risk for vascular damage and new cranial neuropathies postoperatively is significant. READ MORE

  4. 2. Survival of onlay bone grafts. A study in the adult rat

    Author : Monica Gordh; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

    Abstract : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.

  5. 3. Dynamic skull reshaping for sagittal craniosynostosis

    Author : José Guimarães-Ferreira; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Craniosynostosis; Sagittal synostosis; Plastic surgery; Craniofacial; surgery; Spring mediated cranioplasty; Modified pi-plasty; procedure; Roentgencephalometry.;

    Abstract : Objectives: The present investigation was aimed at expanding the knowledge base regarding the skull morphology in sagittal craniosynostosis and at assessing the safety and efficacy of two dynamic cranioplasty procedures, the modified pi-plasty procedure and the spring-mediated cranioplasty. Methods: The patient population consisted of children with non-syndromic sagittal craniosynostosis. READ MORE

  6. 4. Prognostic factors for outcome of benign skull base lesions: The vestibular schwannoma model

    Author : Abdul Rahman Mohummad Al-Shudifat; Neurokirurgi; []
    Keywords : Skull base tumors; Vestibular schwannoma; Prognostic factors;

    Abstract : Skull base tumors comprise different pathological entities, making establishment of management guidelines challenging. All trials to define the ideal outcome measurement which can be reflected on treatment and prognosis improvement, are not conclusive with a lot of methodological criticism. READ MORE

  7. 5. Physical Modeling of Brain and Head Kinematics

    Author : Johan Ivarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Abstract : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. READ MORE
