ABSTRACT

Purpose: Unilateral or asymmetric hearing loss (UHL/AHL) is often under-managed despite its potential effects on articulation accuracy. This longitudinal single-case study aimed to describe language and articulation development in a child with AHL caused by unilateral cochlear nerve deficiency (CND).Methods: Clinical records of a child who began using hearing aids and receiving speech-language therapy at age 2 were retrospectively reviewed. Standardized assessments were conducted between ages 1 and 3, and the results were converted to z-scores.Results: At age 3, language development was within the normal range, whereas articulation accuracy was markedly below expectations, indicating a marked dissociation.Conclusions: This case suggests a marked dissociation between language and articulation development in a child with AHL. This observation underscores the importance of monitoring articulation development, even when language outcomes appear typical.
