  1. 1. Advanced cranial navigation

    Författare :Simon Skyrman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neurosurgery is performed with extremely low margins of error. Surgical inaccuracy may have disastrous consequences. The overall aim of this thesis was to improve accuracy in cranial neurosurgical procedures by the application of new technical aids. LÄS MER

  3. 2. Functional Aspects of Cranial Implants : Mechanical and Regenerative Properties

    Författare :Susanne Lewin; Caroline Öhman-Mägi; Cecilia Persson; Harry van Lenthe; Uppsala universitet; []
    Nyckelord :Calcium phosphate; Ti-6Al-4V; composites; mechanical properties; finite element methods; cranial implants; computed tomography; quantitative image analysis; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : In several neurosurgical procedures, the skull must be temporarily opened. The resulting bone defect can subsequently be reconstructed with a cranial implant. However, the complication rate of this surgical procedure is high (~20%). The most common complication for cranial implants is infection. LÄS MER

  4. 3. Central projections of sensory innervation of cranial vessels

    Författare :Yi Liu; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; Spinothalamic; Neurology; neuropsychology; neurophysiology; Neural tracing; trigeminal nerve; Headache; Cranial vessel; Brainstem; neuropsykologi; neurofysiologi;

    Sammanfattning : Primary headaches (e.g. migraine and cluster headache), the symptoms of which is associated with cranial vascular activity, is likely to be dependent on a primary central nervous system dysfunction. LÄS MER

  5. 4. Aspects of locomotor evolution in the Carnivora (Mammalia)

    Författare :Ki Andersson; Lars E. Holmer; Lars Werdelin; Margaret E. Lewis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morphology; Mammalia; Carnivora; Locomotion; Cranial; Elbow joint; Morphology; Morphometrics; Landmarks; Multivariate statistics; Allometry; Ecomorphology; Dental; Body size; Morfologi; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

    Sammanfattning : In this thesis, the shape of the distal humerus trochlea is analysed using landmark-based morphometrics and multivariate methods, with the aim of exploring locomotor evolution in carnivorans. Elbow joint morphology is used together with body size and craniodental morphology to characterize past and present carnivorans. LÄS MER

  7. 5. Genetic studies of craniosynostosis with focus on syndromic forms

    Författare :Alexandra Topa; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cranial; suture; genetic; diagnostic; next generation sequencing;

    Sammanfattning : Craniosynostosis (CS) represents the premature closure of skull sutures and affects ~1 in 2500 children. Untreated CS can lead to significant complications in craniofacial and psychomotor development. The only treatment available is surgical and requires access to highly specialized healthcare. LÄS MER
