Comparative Analysis of Speech Outcomes in South Korean Preschoolers With Unilateral Congenital Aural Atresia Against a Norm-referenced Standard

When comparing speech parameters in patients with unilateral CAA, it was observed that receptive language abilities were mostly within the normal range. In addition, expressive language abilities were lower than receptive language abilities. The articulation abilities of preschoolers with unilateral CAA enrolled in this study were significantly inferior to those of their normally developing age-matched peers. Hence, preschoolers with unilateral CAA require careful monitoring of language development and appropriate intervention, including bone conduction hearing aids and articulation therapy, when necessary.
