Potential complications of placement include failure of osseointegration, with extrusion of the fixture/abutment skin overgrowth over the abutment and flap necrosis with secondary healing. The use of an osseointegrated bone-conducting device does not preclude future reconstructive surgery. Bilateral implants may impart better sound localization ability and possibly better hearing in noisy environments, but experimentally, this has not been consistently demonstrated. Bilateral osseointegrated bone-conducting devices have even been used for patients with bilateral atresia. Speech reception thresholds (SRTs) of less than 30 dB are obtainable with the use of these devices. This type of osseointegrated technology is more efficient than the bone-conducting hearing aids because the sound energy is not attenuated by the skin and intervening soft tissues. Therefore, one does not need an ear canal or middle ear to hear. A sound transducer attaches to this titanium implant and delivers the sound energy directly to the cochlea via bone conduction. These devices features a surgically implanted, percutaneous titanium fixture-abutment that osseointegrates into the temporal bone. Long-term results of the US experience with osseointegrated bone-conducting devices are also favorable. The active middle ear implants are approved for children aged 12 years or over (Cochlear Osia, Bonebridge).Įxperience using osseointegrated bone-conducting devices is considerable, especially in Europe. The osseointegrated systems are FDA-approved for children aged 5 years or older in the United States. As noted, the bone conductor is strongly recommended for children with bilateral CAA. The benefits of a bone conductor in children with unilateral CAA are unclear and the topic of active research.īoth the osseointegrated bone-conduction systems (Ponto, BAHA Connect, BAHA Attract) and the active middle ear bone conduction systems (Bonebridge, Cochlear Osia) involve surgery to place the osseointegrated titanium implant or middle ear actuator. Alternatives to surgical correction include amplification devices, such as a bone-conducting hearing aid on a soft or hard band worn around the head, or a conventional hearing aid if the auricle development supports placement of a device that is able to provide adequate amplification. The Adhear System (Med-El Medical Electronics) includes an adhesive worn behind the ear to which the speech processor attaches. This device is an alternative to the headband as it does not go around the head. ![]()
