Features of morphometric indicators of the tongue in human fetuses in health and with a cleft of the hard palate
Abstract
The aim of the study is to identify the features of morphometric indicators of the tongue in normal human fetuses and with a cleft of the hard palate.
Material and methods. The object of the study were 41 tongues of human fetuses aged from 16 to 22 weeks of prenatal development. In 2 fetuses (4.9%), a cleft of the hard palate was detected. The study was carried out using methods of macro- and microscopic preparation, morphometry, and the variation-statistical method.
Results. The normal length of the tongue in fetuses of the studied period was 13,8±4,3 mm, the width of the tongue at its widest part – 12,0±2,5 mm, the longitudinal-latitudinal index of the tongue – 130±10%, the angle formed by the terminal groove of the tongue – 112,5±9,9°. Features of the morphometric indicators of the tongue with a cleft of the hard palate can be considered a tendency to increase the length, width at the level of the terminal sulcus, and the length-latitude index.
Conclusion. It is likely that the larger than normal size of the tongue may interfere with the fusion of the palatal shelves or be part of a concomitant pathology. At the moment, the mechanism for the development of such a relationship is not disclosed in the literature. This makes further research using different methodological approaches relevant.
