[Difficulties and peculiarities of diagnosis of hearing disorders in premature infants with perinatal pathology].
Premature infants are highly vulnerable to developing various pathologies including eye and ear diseases; some of them are believed to be associated with specific individual features of gestation and labour course. The study included audiologic screening of 148 babies (296 ears) born prematurely during 24-37 weeks of pregnancy (delayed evoked otoacoustic emission was recorded at the distortion product frequency). For the purpose of dynamic evaluation of hearing ability, all the infants were divided into 3 groups depending on gestational age at birth; they were followed up throughout the first year of life. This paper describes factors complicating pregnancy and labour in women, the most common pathological conditions in premature infants, time and results of their audiologic screening by means of recording delayed evoked otoacoustic emission, algorithm of preliminary examination of premature infants of different gestational age and their selection for audiologic screening, recommendations on the organization of mass audiologic examination of prematurely born infants taking into consideration their gestational and post-conception age.
