¸ñÀû: About more than one out of every 1000 children are born with
hearing loss. Automated auditory brainstem response test is
essential to screen newborns for abnormal hearing. We analyzed the
hearing screening test results at Korea University Anam Hospital in
10 years. ¹æ¹ý:A total of 2890 newborns between August 2005 to January 2015 has
been evaluated with hearing screening test through automated
auditory brainstem response using MASTER ABaer system. Most
screening tests were done within 3 days after birth. If a newborn
was referred, we conducted the test again at once. When refer was
shown again, the test was done within 1 month after being
discharged from the hospital. The results were regarded as pass
when point optimized variance ratio(POVR)>3.5 using stimulus
level of 40 dB. When a newborn was referred at all 3 times of
screening tests, he or she received follow-up tests including
ABR, ASSR and OAE within 3 months. °á°ú:2890 newborns underwent newborn hearing screening test during 10 years. Among them, 36(1.25%) newborns were diagnosed with bilateral hearing impairment. 36(1.25%) of them were diagnosed with hearing loss at right ear, and 30(1.04%) at left ear. Those 102(3.53%) referred newborns were evaluated with additional hearing and speech tests. Also, some of them were provided with hearing rehabilitation through hearing aids or cochlear implants. °á·Ð:It has known that referral rates of Automated auditory brainstem
response test is 3 to 4% as shown in BR Vohr's study. Our data
showed referral rates of 3.53% accordingly. It seems that
automated auditory brainstem response test has been conducted as
a helpful device to screen hearing loss at early stage of
newborns in Korea. |
