Conversion of traditional osseointegrated bone-anchored hearing aids to the Baha® Attract in four pediatric patients

Abstract Bone-anchored hearing aids are external devices attached to the skull via a titanium implant, and can be used for multiple types of hearing loss. Traditionally, osseointegrated implants have been coupled to the external processor with a percutaneous abutment, but more recently, a fully implanted, transcutaneous magnet-based system has become available. Skin reactions from the percutaneous portion are a common complication that can prevent use of the device during critical windows of language development and learning in children. We describe our experience replacing the Baha ® abutment system with the Baha ® Attract in four pediatric patients. Specific operative considerations for incision placement, and magnet and implant coverage are discussed. All patients maintained osseointegration, had excellent long-term wound healing without post-operative infection, and were able to wear their devices more consistently.
