To explore the effect of rat nerve growth factor combined with early rehabilitation intervention in the treatment of hearing injury caused by cytomegalovirus (CMV) infection.

106 cases of hearing impairment caused by cytomegalovirus infection diagnosed in our hospital from January 2012 to February 2018 were randomly divided into observation group and control group, 53 cases in each group. The control group were treated only with ganciclovir and comprehensive rehabilitation therapy, while the treatment group was treated with nerve growth factor on the basis of the control group. Before and after treatment, the children in both groups underwent multi-frequency steady-state evoked potential test, cytomegalovirus antibody DNA fluorescence quantification, and their mothers underwent cytomegalovirus antibody test. The total effective rate of the two groups and the effective rate of the observation group with different degrees of hearing impairment were compared, and the therapeutic effect of the observation group with congenital and acquired CMV infection was compared.

The total effective rate was 80.7% in the observation group, which was higher than 65.9% in the control group (P<0.05). The effective rate of mild to moderate hearing loss in observation group was higher than that in severe hearing impairment (P<0.05). The efficacy of the rat nerve growth factor in the treatment of hearing loss after CMV infection was higher than that of hearing loss caused by congenital cytomegalovirus infection (P<0.05).

Rat nerve growth factor combined with early comprehensive rehabilitation intervention is an effective method to treat acoustic nerve injury caused by CMV infection. The effect of rat nerve growth factor on mild and moderate hearing impairment was better than that of severe hearing impairment. The therapeutic effect of acquired CMV infection on hearing damage was better than that of by congenital infection.
