“Using a combination of sagittal and coronal plane imaging confirmed that when the latch is maintained there is no air present within the oral cavity. In all imaging, the infant's tongue elevates the mother's nipple to the roof of the hard palate, with the lateral sides of the tongue cupping to close the space around the nipple.” “With the MRI images giving an overview of the whole oral cavity, the degree of tongue elevation required appears to be impacted by the height and contour of the infant's hard palate as well as the volume of maternal nipple and areolar tissue. This introduces other anatomical variables that need to be considered (in addition to the infant's frenulum morphology) when assessing for causes of infant sucking dysfunction.”..........
