Bone Conduction Implant by Prof. Dr. Thomas Lenarz

Bone conduction implant surgery by Prof. Dr. Thomas Lenarz offers a sophisticated bypass for individuals with conductive hearing loss, single-sided deafness, or chronic ear canal issues that render traditional hearing aids ineffective. Unlike standard devices that push sound through the air, these implants, such as the Baha or Bonebridge systems, utilize the skull's natural ability to conduct vibrations. Under the precision of Prof. Lenarz, a small titanium implant or an active transducer is integrated into the temporal bone behind the ear. This technology captures sound waves and converts them into mechanical vibrations that travel directly through the bone to the functioning inner ear (cochlea), effectively "short-circuiting" any damage in the outer or middle ear. The clinical advantage of choosing Prof. Lenarz for this procedure is rooted in his active implantation philosophy, which favors transcutaneous (under-the-skin) technology to maintain skin integrity and reduce the risk of long-term inflammation. Research from Hannover Medical School, where Prof. Lenarz has led groundbreaking trials, indicates that active bone-conduction systems provide a significantly higher functional gain in the high-frequency range than older, skin-penetrating abutments. For patients with single-sided deafness, studies have shown that this surgical intervention can improve speech understanding in noisy environments by up to 30% by transferring sound from the deaf side to the healthy cochlea on the opposite side, restoring a 360-degree auditory field. The surgical offer is meticulously guided by high-resolution 3D Imaging (CT) to identify the optimal "bone volume" for stable implant placement. This pre-operative mapping is critical, especially in pediatric cases or patients with congenital malformations of the ear canal, as it ensures the device is anchored in the densest part of the mastoid bone for maximum vibrational efficiency. During the procedure, Prof. Lenarz uses laser-assisted positioning to ensure the transducer is isolated from the skin and hair follicles, preventing feedback or signal damping.
