“…A characteristic feature of the development of suprahyoid muscular triangles of the neck is the uneven growth of their morphometric parameters, due to the different growth rates of the structures that limit it. The morphometric parameters of the SHR were studied at different times by different methods of medical diagnostic imaging, as well as by the method of preparations and measuring the specimens [9,11,12,13,14]. Particular attention should be paid to the periods of slow or accelerated growth of morphometric parameters of the SHR found by many researchers.…”

“…Finding out the features of morphogenesis and topographic changes of suprahyoid region (SHR) of the neck and its structures in the dynamics of human intrauterine development (IUD) remains a relevant area of morphological research [1][2][3][4][5]. Refined, comprehensive data on gender, age and constitutional features of the structure and topography of organs and structures of the SHR of the neck during the prenatal period of human ontogenesis will make it possible to develop new criteria for the interpretation of medical diagnostic imaging data, the degree of fetal viability, improve existing and develop new methods of surgical correction of congenital neck defects [6][7][8][9].…”

The aim: To determine the peculiarities of the morphometric parameters of suprahyoid region of the human prefetuses. Materials and methods: Thirty specimens of human prefetuses of 14.0-80.0 mm parietococcygeal length (PCL) (7-12 weeks of IUD) were studied using a complex of modern methods of morphological research. Results: On the basis of obtained digital indicators of the main morphometric parameters of human SHR in the dynamics of the prenatal period of IUD the critical periods of development of the region were clarified and mathematical functions that describe the normal course of organogenesis of SHR were created, which can be useful for creating diagnostic algorithms for the norm when carrying out prenatal diagnostics and monitoring the state of the fetus. It has been established that the 9-10th week of IUD is a critical period in the development of SHR, since during this time, intensive growth processes occur, which are manifested by a sharp change in the size of the organ, and this can lead to the appearance of variants of the structure and possible congenital defects of the SHR and the dental-maxillary apparatus in general. Conclusions: 1.Age-depended dynamics of changes in the anterior angle of the SHR shows an almost linear decrease in the angle by the end of the 9th week of IUD almost to 76°, after which it increases to almost 90° by the end of the 10th week. From the 11th week of the IUD, the anterior angle decreases again to 77 °, but begins to increase at the 12th week and by the end of the prefeal period. 2.The lateral length of SHR increases almost uniformly until the 9th week of IUD, during which its growth rate slows down. Starting from the end of the 10th week of IUD, this morphometric parameter begins to grow rapidly until the end of the prenatal period of ontogenesis. The growth rate of the lateral length of the SHR is described by the function: L lat = 1.1025 + 0.0015 x + 0.001 x2. 3.The width of the SHR from the 10th week of IUD begins to grow rapidly until the end of the prenatal period of development. The growth rate of the width of SHR is described by the function: W = 1.1025 + 0.0015 x + 0.001 x2. 4.Analysis of the age dynamics of the area of SHR demonstrates the exponential dependence on the age of the prefetuses, which is described by a mathematical function: A = 1,2452exp(0,0424x). Meanwhile, there is a slight slowdown in its growth rate at the 10th week of IUD with subsequent recovery of growth by the end of the prenatal period of ontogenesis. 5.The 9-10th week of IUD is a critical period in the development of SHR, since during this time, intensive growth processes occur, which are manifested by a sharp change in the size of the mandible.

Background The high incidence of non-cardiac congenital anomalies in high-risk pregnancies is a major worldwide health problem. Congenital deformities represent 20–25% of perinatal deaths. The best non-invasive screening method for diagnosing congenital abnormalities is ultrasound. Four-dimensional ultrasound added additional diagnostic value to two-dimensional ultrasound in evaluating fetal prenatal conditions. Our study's goal was to compare the roles of two-dimensional and four-dimensional ultrasound in the diagnosis of non-cardiac fetal congenital anomalies in high-risk pregnancies. Results Out of the 100 pregnant women who underwent examinations, all had high-risk pregnancies and were expected to give birth to babies with deformities, a total of 25 cases (or 25%) of fetal abnormalities were found. The two-dimensional ultrasound diagnosis's accuracy sensitivity, and specificity were 84%, 76%, and 86.67%, respectively, while they were 87%, 80%, and 89.33%, respectively, for four-dimensional ultrasound. The accuracy, sensitivity, and specificity of two-dimensional ultrasound combined with four-dimensional ultrasound were significantly higher (94%, 88%, and 96%, respectively) than those of two-dimensional ultrasound or four-dimensional ultrasound alone. This study also analyzed the risk factors leading to fetal malformations. The results showed that consanguinity, increased maternal age, past history or family history of congenital anomalies, history of medication during pregnancy, and maternal diabetes were major risk factors statistically significant for congenital anomalies. Conclusion The diagnosis rate of fetal abnormalities can be significantly increased by combining two-dimensional ultrasound with four-dimensional ultrasound. Avoiding risk factors that raise the likelihood of fetal abnormalities should take priority for pregnant women with high risk factors. To lower the incidence of fetal abnormalities, prenatal screening and diagnosis should be standardized.
