METHOD OF CONTROLLING AUDITORY FUNCTION MATURATION IN CHILDREN OF DIFFERENT GESTATION AGE WITHIN FIRST HALF YEAR OF LIFE

摘要

FIELD: medicine.;SUBSTANCE: invention relates to field of medicine, namely to otorhinolaryngology. Audiologic examination by method of induced otoacoustic emission at the frequency of distortion product is performed. Tonal acoustic stimuli are sent at frequencies f₁, f₂, satisfying condition f₂/f₁=1.22; f₁f₂, where f₂=1; 2; 4; 6 kHz, and distortion product is registered at frequency F_dp=2f₁-f₂. Children with gestation age less than 28 weeks are examined in 2, 3 and 6 months of life, and with gestation age more than 28 weeks in 3 and 6 months of life. Mean arithmetic value of F_dplevel for all given frequencies of acoustic stimuli is determined, parameter K is calculated by formula: K=A₁-A₂ in dB, where: A₁, A₂ is mean arithmetic value of F_dplevel of current and previous examination. Conclusion about retardation of auditory function maturation in children, born in gestation term less than 28 weeks, is made if K value is lower than 0.55 dB with examination between 2-3 months, and if K is lower than 1.56 dB with examination between 3-6 months, and for children, born with gestation term more than 28 weeks, with K value lower than 0.29 dB with examination between 3-6 months.;EFFECT: method makes it possible to detect possibility of bradyacusia at early stages of child's life.;2 cl, 5 tbl, 4 ex
