骨導インプラントの現状と展望

抄録

Bone conduction is an excellent sound transmission system, and the pathways and characteristics of bone conduction are gradually being better understood. Advances have been made in the development of bone conduction implants, although these are not yet widely used in Japan. Baha^® is the most traditional bone conduction implant, and in recent years, new products with improved performance have been introduced and the indications have been expanded. BONEBRIDGE^® is a new bone conduction implant that began to be covered by the national health insurance in 2021 and can be used in Japan. A new product called Osia^® has also been developed and is increasingly used overseas. In addition, we are developing a novel bone conduction implant using a giant magnetostrictive material (GMM) that offers high output, simplicity of use, a simplified structure (fixed with one screw), and minimally invasive surgery in Japan, to aim for clinical application in the near future.
