OBJECTIVES: The brainstem evoked response audiometry (BERA) is an objective
neurophysiological method for the evaluation of the hearing threshold and
diagnosing retrocochlear lesions. The aim of the study was to investigate the
hearing level in children with suspected hearing loss or pathological speech
development. PATIENTS AND METHODS: The BERA diagnostic procedure was applied in
184 children ranging from 1 to 12 years of age at Ahmadi Hospital in Kuwait.
RESULTS: We found profound hearing loss (deafness) in 13 children, severe hearing
loss in 8 children, moderate hearing loss in 34 children, mild hearing loss in 34
children, and normal hearing level in 95 children. Out of the children suspected
for hearing loss, 42% actually had some level (mild-moderate) of hearing loss.
Out of the children with delayed speech, 63% had some level (mild-profound) of
hearing loss which actually caused the delay in speech development; 37% had
normal hearing, but inadequate verbal communication affected their language
acquisition and speech development. CONCLUSIONS: These results illustrate the
necessity to test children hearing even with the slightest suspicion by the
parent or doctor of hearing loss. The results warrant the establishment of a
hearing screening test of newborns in Kuwait to provide hearing aid to children
with hearing loss.
