摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine and can be used for audiometric diagnostics of idiopathic perilymphatic fistula labyrinths against the background of lability of intracranial pressure. Conduct audiometric control of the acuity of the patients hearing in a soundproofed room. Determine the initial thresholds for the patients sound perception throughout the tone scale at a step of 5 dB. Further the patient lying continuously performs within 60–65 seconds rhythmic deep respiratory movements with a frequency of 20–22 per minute to ensure a decrease in his intracranial pressure. After a pause for 60–65 seconds to stabilize the decreased intracranial pressure, the patient is determined whether there are or are no changes in the sound perception thresholds for air conduction over the entire tone scale at different sound frequencies with a 5 dB study step. In establishing the fact that the sound perception thresholds for the air conduction of the patient are reduced by 10 dB or more at not less than two different frequencies of sounding, the patient has an idiopathic perilymphatic fistula labyrinth.EFFECT: method allows to diagnose with a high degree of reliability, the presence of idiopathic perilymphatic labyrinth fistula on the background of the lability of intracranial pressure, and also provides possibility of reliable diagnostic differentiation in patients of idiopathic perilymphatic fistula of the labyrinth against the background of lability of intracranial pressure from other types of nosology by determining the change in the sound perception thresholds by air conduction over the entire tone scale after performing rhythmic deep respiratory movements.1 cl, 3 exИзобретение относится к медицине и может быть использовано для аудиометрической диагностики идиопатических перилимфатических фистул лабиринта на фоне лабильности внутричерепного давления.
