Outer hair cell functioning in infants with iron deficiency anemia.

Background: Distortion product otoacoustic emissions (DPOAE) in infants with Iron Deficiency Anemia (IDA) helps in understanding the cochlear status especially the functioning of outer hair cells.

Objectives: To analyze the presence of DPOAE across frequencies and DP amplitude in infants with and without IDA.

Method: DPOAE were recorded on 40 infants with IDA and 40 infants without IDA in the age range of 6-24 months.

Auditory brainstem response in infants with iron deficiency anemia.

Background: Auditory brainstem response (ABR) in infants with Iron Deficiency Anemia (IDA) helps in understanding the auditory aspects of central nervous system.

Objectives: To analyse and compare absolute and interpeak latencies of ABR in infants with and without IDA.

Methods: ABR traces were obtained from 40 anemic ears and 40 non anemic ears, aged 6-24 months.
