Insights
Bone-anchored hearing aids (Baha) can benefit children with severe behavioral disorders, even when traditional assessments are not feasible. This study found positive outcomes in a small series of such children.
Area of Science:
- Otolaryngology
- Pediatric Audiology
Background:
- Traditional bone-anchored hearing aid (Baha) candidacy assessment involves bone conductor trials.
- A subset of children with severe behavioral, mental, or sensory disorders cannot undergo this preoperative assessment.
Observation:
- This study reviewed four children with severe behavioral difficulties who received Baha implantation without prior assessment.
- Assessments included the Glasgow Children's Benefit Inventory and a visual analogue scale for health status.
Findings:
- No surgical complications occurred, though intensive postoperative care was needed.
- All children wore their Baha for at least 8 hours daily.
- Parents reported improved child behavior and mood; Baha use positively impacted health status.
Implications:
- Baha implantation can be successful in children with severe behavioral challenges, even without preoperative trials.
- Multidisciplinary teams should consider Baha for these children.
- The success may be linked to the non-invasive physical presence of the Baha device.
Objective:
A trial of a bone conductor is traditionally used to determine whether a bone-anchored hearing aid (Baha) will be beneficial to a child. However there is a subgroup of children where a Baha assessment is not possible due to severe behavioural/mental/sensory disorders. We describe our experience in a small series of such children.
Method:
Retrospective case series review of four children at the severe end of the spectrum of behavioural difficulties who underwent Baha implantation where no formal preoperative hearing aid assessment was possible. The Glasgow Children's Benefit Inventory and a visual analogue scale assessing health status were used to determine the benefit of Baha implantation in this group.
Results:
There was no surgical morbidity in this group although a more intensive postoperative follow up was required. All four children wore their hearing aids at least 8h a day. Parents reported a positive impact of the Baha on the behaviour and mood of their children. The Baha showed a positive benefit when assessed using the Glasgow Children's Benefit Inventory and showed a positive change in health status.
Conclusions:
We feel that our early experience with Baha in children with severe behavioural difficulties has been positive to date. Multidisciplinary teams should not dismiss these children even if a trial of a bone conductor is not possible. We feel that the bone-anchored hearing aid has been successful in our cases because the children do not physically feel the presence of the hearing aid.
