Transient otoacoustic emissions in infants of diabetic mothers.
BACKGROUND
Nursing infants of diabetic mothers require special care.


OBJECTIVE
To verify whether the metabolic alteration during pregnancy is able to alter the cochlear function and the efferent olivocochlear system.


METHODS
Transient otoacoustic emissions of 30 children of diabetic mothers were analyzed, comparing the results to a control group, according to the occurrence and amplitude of the responses.


RESULTS
The children of diabetic mothers presented contractile activity of the outer hair cells with a lower response amplitude.


CONCLUSIONS
The results did not show a statistically significant difference. Further studies with larger samples are necessary.
