Outcomes Following Conversion of a Percutaneous to a Transcutaneous Bone Conduction Device in Eight Children

Abstract

The percutaneous bone conduction device (P-OBCD) is a well-established method of hearing rehabilitation. However, it is associated with soft tissue complications involving the peri-abutment skin.

The magnetic osseointegrated bone conduction (T-OBCD) device overcomes this by leaving an intact skin flap over the implant.

The current study assesses the outcomes of conversion to a T-OBCD in a paediatric population in two tertiary referral paediatric centres.

Eight children underwent conversion. The mean age at conversion was 10 years (range 5-16 years). All had skin reactions between Holgers 3 and 4. Mean improvement in thresholds was 25dBHL.

Conversion from a P-OBCD to a T-OBCD is a safe and beneficial method of hearing rehabilitation in children with persistent soft tissue complications.
