Symptomatic congenital Cytomegalovirus deafness: the impact of a six-week course of antiviral treatment on hearing improvement.

Congenital Cytomegalovirus infection is the leading non-genetic cause of neurosensory deafness. We compared the outcomes of a treated group of children to an untreated group. The effect of antiviral therapy on hearing improvement between baseline and 2-year follow-up was statistically significant. These results suggest that the benefit of 6-week therapy is not limited to preventing further hearing deterioration.
