Abstract

Background:

A bone-anchored hearing aid uses the principle of bone conduction and osseointegration to transfer sound vibrations to a functioning inner ear. It consists of a permanent titanium implant, and removable abutment and sound processor. Informed consent requires discussion of the procedural benefits, alternatives and complications. The risks of bone-anchored hearing aid surgery include infection, soft tissue hypertrophy, skin graft or flap failure, osseointegration failure, and the need for further surgery.

Case report:

A case of cerebrospinal fluid leak in a patient undergoing bone-anchored hearing aid surgery is reported and discussed.

Conclusion:

Bone-anchored hearing aid surgery poses a risk of breaching the inner table of the temporal bone and dura, resulting in a cerebrospinal fluid leak; the risk of meningitis is rare but serious. The surgeon should discuss the possibility of cerebrospinal fluid leak when consenting patients. Pre-operative computerised tomography scanning should be considered in certain individuals to aid implant placement.
