ABSTRACT
Congenital cytomegalovirus infection (CMVI) is known to be one of the root causes of the development of sensorineural hearing loss in children, however, the problem of occurrence of central auditory processing disorder (CAPD) remains underinvestigated. The objective of the study was to assess the prevalence of CAPD in children with congenital CMVI, and to develop an examination algorithm including the assessment of central departments of the auditory system. At the first stage, the peripheral hearing was examined in 121 children. Among 60 patients with congenital CMVI, sensorineural hearing loss (SNHL) was revealed in 16.7%, in 30% of them it occurred with delay; examination of 61 children with the similar hearing loss risk factors, but without CMVI, revealed 4.9% of children with hearing impairment, with no delayed SNHL cases. At the second stage, the function of central departments of the auditory system was assessed in children aged from 4 to 7 years old with normal peripheral hearing level: the main group included 10 patients with congenital CMVI; the comparison group consisted of 10 patients with the similar hearing loss risk factors but without CMVI. The speech audiometry results were better in the comparison group; however, in both groups, they were lower than the rated value. The data obtained indicate that children with congenital CMV have higher SNHL and CADP incidence rate.
