Objectives/Hypothesis: Congenital cytomegalovirus (cCMV) infection is a common cause of sensorineural hearing loss (SNHL). The incidence of SNHL is higher in symptomatic cCMV infants and is usually identified early. By contrast, the incidence of SNHL is lower in children with asymptomatic cCMV, and the hearing loss can be delayed in onset and progressive. The objective was to compare the outcome of cochlear implantation in children deafened by cCMV with a control group of children with implants who do not have the condition. Study Design: Retrospective review of case notes and data base. Methods: Retrospective review of 14 children with asymptomatic cCMV who underwent cochlear implantation. Their outcome measures were compared with those of a matched population by using standard assessment tools. Results: In the study group, the Modified Categories of Auditory Performance (M‐CAP) score (range, 1–7) ranged from 2 to 7 (mean, 4.2). In the control group, the M‐CAP ranged from 5 to 7 (mean, 6.0). In the study group, the Manchester Spoken Language Development Scale (MSLDS) score (range, 1–10) ranged from 1 to 9 (mean, 5.4). In the control group, the MSLDS ranged from 3 to 10 (mean, 8.1). Conclusions: Children with asymptomatic deafness caused by cCMV benefit from cochlear implantation but perform less well than a comparable group of children with implants who do not have cCMV. There is a range of performance in the cCMV group that may relate to the degree of motor or cognitive disabilities.
