The implant-site split-skin graft technique for the bone-anchored hearing aid.

Abstract

We describe the technique of implant-site split-skin grafting for the bone-anchored hearing aid (BAHA). Twenty-five patients have undergone this procedure (20 adults and five children) since 1993 with a minimum follow-up of 1 year. Fifteen adults were operated upon as single stage surgery, all other cases (including all children) were performed in two stages. In four patients (16%) significant early graft inflammation was encountered which settled with outpatient treatment. In one the abutment had to be temporarily removed to allow the graft to settle. All patients now have a stable graft site. This surgical technique is straightforward and a separate graft donor site is avoided. It would appear this technique results in a stable BAHA graft site with low associated morbidity.
