The School-Age Child With a Unilateral Loss and a Bad Report Card
An 8-year-old second grader is referred by her teacher for suspected attention problems. She is falling behind in reading and often misses instructions. Audiometry shows a moderate-to-severe sensorineural loss in the left ear (PTA 65 dB HL) and normal hearing in the right ear. The loss was identified at age 3 but the family was told "one good ear is enough" and no amplification or FM system was provided. Speech recognition in the right ear is 96% in quiet but drops to 68% in competing noise (classroom-like). Tympanometry is normal. The child has no other diagnosed disabilities.
1. Is the teacher's concern about attention justified, or is hearing the cause? How do you distinguish?
Read the worked answer
Hearing is the more likely primary cause, though attention and hearing can interact. Distinguishing factors:
- Unilateral loss is not benign: children with unilateral hearing loss have higher rates of grade retention, need for extra help, and listening fatigue. In a noisy classroom, her right-ear speech recognition falls from 96% to 68% - a 28-point drop that means she misses a substantial fraction of instruction, especially when sound comes from her left side or the room is reverberant.
- She must turn her head to favor the good ear, which looks like inattention, and listening fatigue mimics attention deficits by afternoon.
- To distinguish: obtain teacher and parent questionnaires (e.g., CHILD, LIFE-R), classroom observation, and a speech-in-noise test with spatial separation (speech front, noise to the left). If performance improves with a remote microphone, hearing is driving the problem. Rule out ADHD only after hearing access is optimized - do not accept an ADHD label before fitting technology.
Recommend a full psychoeducational evaluation after hearing access is addressed.
2. What intervention plan do you recommend, and what does the evidence say about 'one good ear is enough'?
Read the worked answer
Plan:
- Remote microphone (FM/DM) system with a receiver on the right ear - the single most effective classroom accommodation for unilateral loss.
- Hearing aid or CROS/bone-conduction device on the left ear may be considered, but a CROS can be difficult for a child to accept and does not restore localization; an FM system is the priority.
- IEP/504 plan with preferential seating (front, good ear toward teacher), reduced background noise, captioned videos, and teacher training.
- Auditory training and monitoring every 6-12 months; watch for progression.
- Address reading difficulty with the school team.
Evidence: The "one good ear is enough" advice is outdated and wrong. Unilateral hearing loss is associated with educational risk - more grade retention, more IEP use, and poorer speech-in-noise performance. Early amplification/remote-microphone access improves outcomes. Document this to counter the earlier advice and advocate for services.
3. What would you tell the parents who were previously reassured, and how do you handle the school's request for an ADHD evaluation?
Read the worked answer
To parents: Be honest but supportive - explain that the earlier advice was based on an older view and that current evidence shows unilateral loss affects learning, especially in noise. Show them the speech-in-noise data (96% → 68%). Emphasize that this is fixable and that addressing hearing now can prevent further academic decline. Avoid blaming them; focus on the plan and the child's potential.
To the school: Recommend that the ADHD evaluation proceed only after hearing access is optimized (remote microphone, seating, classroom acoustics) for a defined trial period (e.g., 6-8 weeks), with teacher questionnaires before and after. This avoids mislabeling a hearing-access problem as ADHD. Provide the school with the audiogram, speech-in-noise results, and a written accommodation plan. Coordinate with the school audiologist/speech-language pathologist and document all recommendations.
