The study aimed at describing a case of auditory brainstem implant (ABI) paediatric re-implantation performed at the Akademiska University Hospital, Sweden. The patient was a boy with Goldenhar syndrome with absent vestibular-cochlear nerves and was first implanted with an ABI in 2009 at the age of two years. A technical device failure in 2015 led to a re-implantation at the age of nine years. The ABI was successfully re-implanted although the implant was closely attached to the surrounding

After 12 months, the patient's hearing thresholds was not as good as it was after the primary implant, but it is still developing. The child is a full-time user. ABI re-implantation is possible even after many years, although there is a risk that the implant might be fixed to the brainstem and difficult to remove. ARTICLE HISTORY
