Considering Antiviral Treatment to Preserve Hearing in Congenital CMV.

The authors comment on antiviral treatment to preserve hearing in congenital cytomegalovirus (cCMV), the leading nongenetic cause of sensorineural hearing loss (SNHL) in children. Topics discussed include reason newborns are usually tested for cCMV, clinical trials about ganciclovir or valganciclovir conducted by the Collaborative Antiviral Study Group (CASG) and lack of evidence of the efficacy of antiviral medication on hearing preservation in infants with asymptomatic cCMV.
