Ten premature infants with low serum thyroxine levels (less than 84 nmol/L) were compared
with 10 biochemically euthyroid infants to determine whether hypothyroxinemia in such …

To evaluate the effect of early treatment of congenital hypothyroidism on central nervous
system development, auditory brainstem evoked potentials were determined in 32 patients …

Pure tone audiometry, tympanometry, acoustic stapedial reflex thresholds (ASRTs), and
auditory evoked brain stem responses (AEBRs) were carried out in 38 children with early …

Maturation of the peripheral auditory system was monitored with the brainstem response
audiometry (BSRA) technique in l-thyroxine (T 4)-injected rats. Neonatal hyperthyroidism …

Using auditory brainstem response audiometry, we evaluated 34 congenital hypothyroidism
children under thyroid hormone therapy and 24 age-and sex-matched controls between 5 …

Eleven congential hypothyroid newborns were consecutively referred for audiological
evaluation before any treatment. Evoked otoacoustic emissions were present bilaterally in 9 …

Thyroid hormones are essential to the maturation of the central nervous system and sensory
organs. Hypothyroidism induces various kinds of neural retardation, including hearing …

We report the results of a longitudinal study of auditory brain-stem responses (ABRs) and
somatosensory evoked potentials (SEPs) performed in 6 children with congenital …

At the present, the influence of intrauterine hypothyroidism on the fetus is estimated by bone
age (BA). BA is also used as a predictor of later neuropsychologic development. The aim of …

Clinical studies have demonstrated that hypothyroidism may occasionally be associated
with deafness 11. Some histological observations made on chick embryos and newborn …
