Abstract. This article explains the state of the ENT organs in twins and the rhythmic manifestations of life changes in them. Based on this article, it will be possible to find out what diseases of the throat, nose and the auditory system are susceptible to children born on the basis of multiple pregnancies. To assess the role of hereditary and environmental factors and the development of diseases, pathological changes in the functional and anatomical aspects of the ENT organs in Gemini are still observed. In addition, in Gemini, the pathology of anatomical and physiological defects of the ENT organs is more common in twin children in the perinatal period, in comparison with children born alone. Changes associated with the work of the respiratory organs and the same systems are becoming more and more noticeable, including with the formation of ENT organs and, in particular, a sound analyzer, a deviation of the nasal barrier, nasal congestion and, accordingly, an increase in defects that further will exert their influence on other organs of the body.
