Uate, progress, or be delayed; therefore, careful hearing monitoring needs to be continued. Infants diagnosed with cCMV infection call for long-term follow-up, even if they pass NHS. The Joint Committee of Infant Hearing 2019 suggestions advocate that follow-up audiologic assessment of infants with cCMV infection is performed when they are no older than three months [16]. Within this study, 67 of cases had bilateral SNHL and 33 of circumstances had unilateral SNHL, which is constant with preceding cohort studies. As outlined by eight cohort studies [3], hearing loss as a consequence of cCMV infection was bilateral in 60 of instances and unilateral in 40 of instances (Table 1). A total of 55 of circumstances had bilateral severe-to-profound SNHL and cochlear implants should be regarded in these instances, 25 of instances had late-onset SNHL, and 43 of circumstances had progressive SNHL. The incidence of SNHL as a consequence of cCMV infection depends upon the timing of CMV infection for the duration of pregnancy. SNHL was detected in 80 and 8 of congenitally infected youngsters who were infected just after a major maternal infection within the first and second trimester of pregnancy, respectively, and was not detected soon after principal maternal infection inside the third trimester of pregnancy [22].Table 1.

Conclusions About 8 of men and women with unilateral or bilateral hearing loss of unknown etiology were good for cCMV infection. cCMV-related hearing loss is extremely heterogeneous and there is a higher risk of missing this situation by means of NHS. Even though immediate CMV screening is advisable for infants who do not pass NHS, such targeted cCMV screening will not capture infections that lead to late-onset hearing loss. Universal cCMV screening gives larger net savings as well as the greatest chance to supply directed care.Author Contributions: Conceptualization, S.B.M.; formal analysis, Y.Y.; investigation, A.N., H.S., S.M., T.T., S.K., T.S., N.M., K.K. and T.M.; information curation, Y.Y.; writing–original draft preparation, S.B.M.; writing–review and editing, S.B.M. and T.M.; supervision, T.M.
