Surgical experience with bone-anchored hearing aids in children.
Titanium osseointegrated implants for bone-anchored hearing aids (BAHAs) have been in use since 1977. A series of 32 children who received implantation since 1990 is reported. The report focuses on the surgical aspects of BAHAs, predisposing factors, and prevention of complications in an unusual pediatric population. The records of 32 children who had undergone two-stage implantation of a BAHA were retrospectively reviewed. The majority of the patients had craniofacial abnormalities. Of the 32 implantees, 29 use their BAHA at present. Five children failed to achieve osseointegration, and eight patients have had revision surgery for lost abutments, trauma, or chronic skin problems. There were no differences between preimplantation and postimplantation bone or air conduction thresholds. The pediatric BAHA carries with it a unique set of challenges and problems but can be successfully implanted and maintained.
