ABSTRACT
Today acoustic impedansometry is one of the main methods of diagnostics of the state of acoustic analyzer both in adults and in children, it is represented by various techniques of analysis of external and middle ear structures: the change of sounding tone frequency, the tests of auditory tube function. However, the same type of tympanometric curve may describe several pathological conditions, sometimes this type does not fall under the existing classification suggested by Jerger in 1970, which results in low diagnostic value of this acoustic analyzer examination method and sometimes even causes misdiagnosis. Besides, the classical variant of tympanometric examination, predominantly at the sounding tone frequency of 226 and 1000 Hz, has a great number of limiting factors, especially during the first year of the child’s life. All these factors complicate hearing disorders diagnostics and results in the distortion of the results and, subsequently, incorrect treatment, establishment of disability group, etc. Special attention is paid to children’s practice as this category of patients is the most difficult. It should be noted that early rehabilitation intervention, its quality, and further control are extremely important for speech skills training and further integration into society.
