The hearing screening of newborns
depends on the development and financial support of health care
system of each country. Therefore it is often preferable to performed
a targeted screening on newborns at risk for hearing impairment,
although the universal screening would be preferable. In this short
report, we present the initial results from screening newborns at
risk at the University Clinical Center in Ljubljana.
Newborns from the Neonatal
Intensive Care and those with a family history for hearing impairment
were tested at the Department of Obstetrics and Gynecology. Transient
Otoacoustic Emissions (TEOAEs) were measured with the Echo-Screen
Plus( from Madsen). If a TEOAE response was absent, the test was
repeated before discharging the newborn from the hospital. Those
with absent TEOAEs on both ears were referred to the Audiologic
Department of the ENT Clinic. During 2002, 1300 newborns
at risk underwent hearing screening.and 38 of them
were referred to the Audiologic Department. After taking the history
of the disease, we perfomed the ENT examination, tympanometry, free
field audiometry, and TEOAE and Auditory Brainstem Response measurements.
TEOAEs were present in 27 and absent in 11
of the 38 newborns. 4 of 11 newborns
with absent TEOAE had conductive hearing impairment
and were treated by conservative or operative treatment. In all
4 newborns TEOAEs were present after the treatment. 7
newborns had sensorineural hearing impairment, which is 18.4
% of the newborns referred from Department of Obstetrics
and 2.92 % of the total number of tested newborns.
Our results confirm the higher rate of hearing imapirment in newborns
at risk. We can also confirm the need of having staff with a high
level of trainin in order to perform properly the OAE measurements.
