A 12-year-old child with bilateral congenital microtia and ear canal atresia was bilaterally implanted with a Vibrant Soundbridge (VSB) on the right side and a Bonebridge on the left side. Prior to these surgeries the child was using percutaneous bone conduction devices (BCDs) on a headband for more than 9 years. No complications occurred during the surgeries. Sound field audiological testing showed cumulative benefit when both devices were used simultaneously. Directional hearing was tested in a sound-attenuated room. To ensure that the subject could only use acoustic information to localize sounds, the test was performed in complete darkness. The ability to localize sounds was poor when listening with either the VSB or Bonebridge, but increased significantly when both devices were used simultaneously. To our knowledge this is the first case report about the bilateral implantation of a VSB and Bonebridge.
