We observed, for six years, the degree of hearingloss of the 55 young deafend children who have been using hearing aid from 1 to 3 years of age.
The results were as follows:
1) About 10% of the young deafened children grow worse in hearing.
2) The further destruction of hearing is noticed at higher percentage among the endogenious deafened children than among the exogenious deafened ones.
3) There is possibility of the further destruction of hearing by the use of hearing aid, but at the same time, pediatric diseases caused by virus infection or by some other factors are possibly to be its causes.
4) The further destruction of deafend children's hearing is to occur all through infancy, but it is especially remarkable at about 7.
