The Birmingham bone anchored hearing aid programme: surgical methods and complications

Abstract

AbstractSince 1988, 309 patients have been referred to the Birmingham bone anchored hearing aid programme for assessment. One hundred and eighty-eight have been fitted with bone anchored hearing aids (BAHA). Of these 169 have been fitted with a BAHA alone and 20 with a BAHA and auricular prosthesis(es).Only four (2.1 per cent) are not wearing their BAHAs. Three cases because the hearing had continued to deteriorate and in one case because of repeated failure to integrate. Nineteen patients (10.1 per cent) have lost fixtures but all but one of these have been successfully reimplanted. Of these 19 patients 10 (52.6 per cent) were syndromal and 10 (52.6 per cent) were under 16 years of age.A surgical method has been evolved both to cope with predictable failure of integration and soft tissue control.
