Two patients with bilateral congenital atresia who wore digital bone-conduction hearing aids (DBCA) behind the ear are reported here.
No developmental delay in speech, language, or auditory perception was observed after more than 4 years of education at our institution, compared to their hearing peers. Because they suffered from environmental noise and poor speech perception in noisy circumstances while wearing conventional bone-conduction hearing aids, we fitted them with digital bone-conduction hearing aids remade from digital hearing aids.
Marked improvement in speech intelligibility in noise and less suffering from unpleasant noise was observed after subjects began wearing digital bone conduction hearing aids (DBCHA).
These results suggest that DBCHA fitting is highly effective and may play an important role during rehabilitation for children with congenital aural atresia and microtia.
