OSSEOINTEGRATED IMPLANTS IN THE MANAGEMENT OF CHILDHOOD EAR ABNORMALITIES - THE INITIAL BIRMINGHAM EXPERIENCE

Over a four-year period 72 children with ear abnormalities have been referred for assessment by the extraoral osseointegrated implant team at The Queen Elizabeth Hospital, Birmingham. Thirty-two children have been judged suitable for rehabilitation. Twelve children have completed rehabilitation using bone-anchored hearing aids and/or auricular prostheses. Two fixtures (seven per cent of those loaded) have dislodged and required replacement. Audiological assessment of the bone-anchored hearing aid users shows only small improvements in their aided thresholds, compared to thresholds obtained with their previous aid. However all now have thresholds of 30 dB(A) or better and report a marked improvement in sound quality. When surveyed, hearing aid and prosthesis users report high levels of satisfaction with this form of rehabilitation. The technique adds a new dimension to the management of children with aural anomalies. The approach and results of a multidisciplinary programme are reported.
