title: [The functional state of the cochlea in premature infants born before 28 weeks gestation on the 6th month of life].
abstract: The objective of the present study was to assess the state of the peripheral portion of the auditory analyzer based on induced otoacoustic emissions (IOAEs), distortion product otoacoustic emissions (DPOAEs), and delayed IOAEs (DIOAEs). The study included 31 premature infants born before 28 weeks gestation and examined later on the 6th month of postnatal life. All of them were shown to have the underdeveloped cochlea. It was shown that the DPOAEs technique makes it possible to record induced otoacoustic emissions more frequently than the DIOAEs method. It is concluded that the hearing function in premature infants born before 28 weeks gestation should be evaluated on the 6th month of postnatal life based on two classes of emission.
