6. The Balanced Electromagnetic Separation Transducer for Bone Conduction Audiometry and Hearing Rehabilitation
Sammanfattning : Hearing via air conduction (AC) and bone conduction (BC) are attributed to bethe natural ways of conducting sound to the cochlea. With AC hearing, air pressurevariations are transmitted to the cochlea via the ear canal, whereas with BChearing, sound vibrations are transmitted through the skull bone to the cochlea. LÄS MER
7. On Direct Drive Bone Conduction Devices - Hearing Rehabilitation and Objective Assessment of Stimulation Methods
Sammanfattning : Bone conduction devices (BCDs) rely on the transmission of sound in form of vibrations generated by a transducer to the inner ear via the skull and surrounding soft tissues. Direct drive BCDs stimulate the skull bone directly, either via a skin-penetrating abutment (BAHAs, Bone Anchored Hearing Aids), or with a transducer implanted under intact skin (active transcutaneous devices).

8. Allograft bone in hip revision: the effect of locally applied pharmacological treatment
Sammanfattning : The clinical success of primary hip replacement is paramount but the need for revisions will continue to increase due to the increasing number of operated individuals. In Sweden, the number of hip revisions in 2012 exceeded 2,300. During implant loosening, some of the bone in the femur is lost, which can make the revision more difficult. LÄS MER
9. Basic fibroblast growth factor for stimulation of bone formation in osteoinductive and conductive implants
Sammanfattning : Basic Fibroblast Growth Factor (bFGF) is one of the endogenous factors found in bone matrix. bFGF is a mitogen for many cell types, including osteoblasts and chondrocytes. It can stimulate angiogenesis and osteoblast gene expression. LÄS MER
10. The Bone Conduction Implant (BCI) - Preclinical Studies, Technical Design and a Clinical Evaluation
Sammanfattning : The Bone Conduction Implant (BCI) system has been developed as an alternative to the percutaneous bone anchored hearing aid (BAHA) with the advantage that the skin is kept intact. The transducer is permanently implanted and attached to the skull via a flat surface contact to the temporal bone. LÄS MER
