1. Middle Ear Cholesteatoma : Surgical Treatment, Follow-up and Hearing Restoration
Sammanfattning : Although middle-ear cholesteatoma is a major topic in otological research, its etiology and pathogenesis remain unclear. Pediatric cholesteatoma is considered more aggressive than adult cholesteatoma, as it has a higher rate of growth, is more often infected and exhibits wider extension. LÄS MER
2. MRI Studies of the Fetal Brain and Cranium
Sammanfattning : Ultrasound is the primary modality for fetal imaging, but Magnetic Resonance Imaging nowadays has a valuable complementary role as it often reveals findings that alter pregnancy management. Knowledge on some clinically relevant areas of the normal fetal development is still lacking, and this was the aim of this project. LÄS MER
3. Local pharmacological treatment of inner ear disorders
Sammanfattning : Hearing disorders are among the top 10 in terms of burden of disease in middle- and high-income countries, affecting 250 million people worldwide. During the last few decades researchers have made significant advances in understanding the basic mechanisms and molecular biology of inner ear diseases. LÄS MER
4. Growing up with one ear : central auditory structure and function in unilateral ear canal atresia
Sammanfattning : The following thesis aims to give more insight into the functional and structural response of the central auditory system to congenital unilateral ear canal atresia (UCA) and the accompanying asymmetric hearing with conductive hearing loss on the atretic side. There is clear evidence that unilateral hearing loss, including UCA, has a negative impact on sound localization ability and perception of speech in noise. LÄS MER
5. The Human Vestibular Aqueduct, Endolymphatic Duct and Sac : A Morphological Study Using Micro-CT, Super Resolution Immunohistochemistry and Synchrotron Phase Contrast Imaging
Sammanfattning : The inner ear lies sheltered in the temporal bone and consists of basically three parts: the cochlea (the hearing organ), the vestibular (the balance organ), and the endolymphatic duct (ED) and endolymphatic sac (ES). The ES and ED are located in a bony canal, the vestibular aqueduct (VA), located on the medial side of the vestibule. LÄS MER
