Bonebridge transcutaneous bone conduction implant in children with congenital aural atresia: surgical and audiological outcomes

  • L X Ngui (a1) and I P Tang (a1) (a2)



To investigate the surgical and audiological outcomes of the Bonebridge transcutaneous bone conduction hearing implant among children with congenital aural atresia.


Six children were recruited and underwent Bonebridge transcutaneous bone conduction implant surgery. The patients’ audiometric thresholds for air conduction, bone conduction and sound-field tests were assessed pre-operatively and at six months post-operatively. Patients’ satisfaction was assessed at six months post-operatively with the Hearing Device Satisfaction Scale.


No major complications were reported. Mean aided sound-field thresholds improved post-operatively by more than 30 dB for 0.5–4 kHz (p < 0.05). Mean unaided air conduction and bone conduction thresholds differed by less than 5 dB post-operatively (compared to pre-operatively) for 0.5–4 kHz; these findings were not significant (p > 0.05). All patients were satisfied (scores were over 90 per cent) with the implant in terms of functional outcome and cosmetic appearance.


Bonebridge transcutaneous bone conduction implant surgery is safe and effective among children with congenital aural atresia with conductive hearing loss.
