A report of three cases and review of auditory brainstem implants in children
Copyright © 2014 Elsevier Masson SAS. All rights reserved..
AIM OF THE STUDY: To present three pediatric cases of auditory brainstem implantation (ABI) and review literature data concerning this topic.
PATIENTS: The first two children had a neurofibromatosis type II with bilateral sensorineural deafness; in both cases, the implant was inserted during the surgical removal of a vestibular schwannoma; the third patient had profound deafness due to bilateral cochlear nerve insufficiency associated with inner ear malformation.
RESULTS: Two postoperative complications were observed: patient 1 had a persistent fever which required the replacement of the fat graft used to seal the translabyrinthine approach; patient 3 had a CSF leakage requiring additional surgery and lumbar external drainage. In our three patients, the numbers of active electrodes were 6/22 (Cochlear ABI 24M ABI), 11/12 (Medel Opus II ABI) and 11/12 (implant Medel), respectively. Due to additional major surgical procedures and to disappointing functional results of the ABI, patient 1 stopped wearing her implant 18 months after implantation. Nine months after surgery, patient 2 achieved open-set speech recognition and was very satisfied with the implant. Six months after implantation, patient 3 (cochlear nerve deficiency), who was 3.5 years-old at the time, clearly reacted to some environmental sounds but was not yet able to achieve speech recognition.
CONCLUSIONS: ABI has now entered the list of treatments that can be proposed in pediatric profound sensorineural deafness. Its major risks of complications are CSF leakage and non-auditory side effects. Its outcomes are worse and less predictable than cochlear implants. Thus, its indications must remain restricted to cases meeting the following conditions: absence of alternative option to restore hearing, patients and parents high level of motivation and realistic expectations.
