U. Finckhkramer et al., AGE AT DIAGNOSIS FOR PERSISTING HEARING-LOSS IN CHILDREN STILL TOO LATE, HNO. Hals-, Nasen-, Ohrenarzte, 46(6), 1998, pp. 598-602
Since 1994, the German Registry for Hearing Loss in Children has regis
tered data of 1500 children and by now can present results concerning
the age at diagnosis of permanent hearing loss in children in Germany.
The mean age at diagnosis is still very high.There is a strong correla
tion between age at diagnosis and degree of hearing loss, i.e., severe
and profound healing loss, is diagnosed distinctly earlier than mild
and moderate hearing loss.On average, mild hearing loss is diagnosed w
ith 6.2 years, moderate h.l. with 4.4 years, severe hearing loss with
2.5 years and profound hearing loss with 1.9 years. This corresponds w
ith the results of regional German studies. At least regionally, in ot
her European countries the age at diagnosis is known to be distinctly
fewer.ln 36% of the children registered in Germany the delay between f
irst suspicion and diagnosis of permanent hearing loss is 1 year or mo
re.
