Clinical Characteristics of Children With Single-Sided Deafness Presenting for Candidacy Assessment for Unilateral Cochlear Implantation

Abstract

Purpose of Review

Children with unilateral deafness may experience challenges with language development, educational progress, and social interaction. Rehabilitation with a cochlear implant (CI) may minimize these impacts. This review examines the characteristics of children with unilateral deafness presenting for candidacy assessment.

Recent Findings

Forty-nine children with unilateral deafness were assessed. Many (15/49) did not meet candidacy criteria due to cochlear nerve aplasia/hypoplasia (12/49), while 17/49 elected not to pursue CI. The most common etiologies in those 17/49 (35%) who met candidacy and consented to CI were congenital cytomegalovirus (cCMV) (41%) and trauma (26%).

Summary

Many children with unilateral deafness who present for assessment do not go on to receive an implant due to anatomic contraindications or their desire for non-intervention. This review highlights the high prevalence of cCMV amongst children with unilateral deafness presenting for CI where the potential for progression to bilateral hearing loss may influence decision for implantation.
