The main question it aims to answer is: Does the thickness of the masseter muscle influence the course of development of the feeding function in premature newborns? The study will assess the influence of masseter muscle thickness on the oral feeding process in premature infants, which has significant cognitive value due to the dynamic development of feeding function in this group of newborns. Transitioning from enteral feeding via a nasogastric tube to full oral feeding is a crucial stage in the development of one of the most fundamental life functions - nutrition. Complete, effective, and safe oral feeding is also a factor in determining a newborn's discharge from the hospital. Research in the area of feeding is an important and ongoing goal for improving neonatal care in neonatal units. Furthermore, this study will provide preliminary data on masseter muscle thickness in premature infants, which may serve as a basis for further research.",[35],"Premature Infants",[37,38,39,40],"premature infant","masseter muscle","ultrasonography","oral feeding","NOT_YET_RECRUITING","2026-06-14",{"date":44,"type":45},"2026-06-18","ACTUAL",{"date":47,"type":30},"2026-06",{"date":49,"type":30},"2029-12",{"name":5,"class":6}]
