Item The topographic classification of the human renal pyramids(ТДМУ, 2013-10) Масловський, Сергій Юрійович; Масловский, Сергей Юрьевич; Maslovsky, Sergey; Дуденко, Владимир Григорьевич; Дуденко, Володимир Григорович; Dudenko, Volodymyr; Вдовиченко, В.І.; Вдовиченко, В.І.; Vdovichenko, V.; Ворощук, Р.С.; Ворощук, Р.С.; Voroshchuk, R.Publication Range of variability of the morphometric indicators of the piriform aperture of men depending on craniotype(Приватний вищий навчальний заклад «Харківський міжнародний медичний університет», 2024) Boiagina, O.; Боягіна, Ольга Дмитрівна; Melnyk, B.; Samosudova, L.; Самосудова, Людмила ВікторівнаThe maxillofacial region is an anatomically complex area that includes structures of a peculiar shape. This can add difficulty to their display on tomograms and complicate the interpretation of these images. Therefore, perfect knowledge of the tomographic anatomy of the maxillofacial region is absolutely necessary. The aim was to study the morphometric parameters of the piriform aperture of men depending on the craniotype. Conclusions. 1. The range of variability of the height, width, perimeter and area of the piriform aperture of men is determined. 2. It was established that the investigated parameters do not depend on the type of facial skull structure.Item Clusters of fractal dimension of the human cerebellum (magnetic resonance imaging study)(2020) Мар’єнко, Наталія Іванівна; Марьенко, Наталия Ивановна; Maryenko, NataliiaItem Arbor vitae cerebelli: fractal properties and their quantitative assessment by novel “contour scaling” fractal analysis method (an anatomical study)(Translational Research in Anatomy, 2024) Maryenko, Natalia; Мар'єнко, Наталія Іванівна; Stepanenko, Oleksandr; Степаненко, Олександр ЮрійовичArbor vitae cerebelli (tree-like branching white matter of the cerebellum) has a complex spatial configuration that is challenging to assess using conventional morphometric methods. This study proposes a fractal approach to describe and quantify the anatomy of Arbor vitae cerebelli. For this purpose, a new “contour scaling” method for fractal analysis of cerebellar white matter was developed. The fractal (Hausdorff) dimension, determined using the novel “contour scaling” method, quantitatively assesses the degree of branching of the cerebellar white matter. An increase in the absolute size of the cerebellum leads to a higher degree of branching of its white matter and an increase in the number of its constitutive components – white matter branches and folia.Item Fractal analysis of images in medicine and morphology: basic principles and methodologies(ДДМУ, 2021) Maryenko, Nataliia; Stepanenko, OleksandrItem Digestive system. Part 2 (intestine, liver, pancreas)(2012) Shestitko, IreneItem Anatomical predictions of development of rhinosinusitis and its complications(ХНМУ, 2020) Alieksieieva, Victoriia; Алєксєєва, Вікторія Вікторівна; Алексеева, Виктория ВикторовнаBackground. The anatomical structure of the paranasal sinuses of a person predetermines the risk of development, diversity of presentation, possibility of complications and features of surgical treatment of rhinosinusitis. Objective: of our study was to determine the thickness and density of the walls of the maxillary and frontal sinuses, which are potentially dangerous in terms of the development of complications. Materials and methods: Our study involved 121 subjects without any ENT diseases, who underwent SCT examination due to the reasons that were not related to abnormalities of ENT organs. Thickness and density in the region of the lower (orbital) wall and posterior (cerebral) wall of the frontal sinus were calculated. Results and Discussion. The maximum density was characteristic of the lower wall of the frontal sinus under physiological conditions and appeared 107.96 ± 201.64 Hu, the minimum for the lower wall was -29.98 ± 208.54 Hu. The thickness of the bone tissue in the frontal sinus was 4.05 ± 2.04 mm. Conclusion. The minimum density and thickness of the lower and posterior walls of the frontal sinus and upper and lower walls of the maxillary sinus was established under physiological conditions. The density of the posterior wall was found to be 25.4% lower than the density of the lower wall, and the thickness 22.2% lower.Item Muscle tissue(2013-04-18) Степаненко, Олександр Юрійович; Степаненко, Александр Юрьевич; Stepanenko, OleksandrItem Male Reproductive System(2012) Степаненко, Олександр Юрійович; Степаненко, Александр Юрьевич; Stepanenko, OleksandrItem Individual anatomical variability of the anteroposterior lateral dimensions of the facial skull in mature adults(Georgian medical news, 2024) Sosonna, L.; Boiagina, O.; Боягіна, Ольга Дмитрівна; Yurevych, N.; Schevtsov, O.; Avilova, O.; Konoval, N.; Sukhina, I.Despite the significance of anatomical variability in various specialties, there is currently limited research dedicated to this topic. Most studies focus on the brain, with only a small number examining the human skull, primarily in relation to anatomical variability in childhood. Aim: Therefore, the aim of our work is to determine the individual anatomical variability of the lateral dimensions of the facial section of the adult human skull. Materials and methods: The study included 115 skulls of mature individuals, comprising 35 dry bone specimens from the anatomy museum collection and 80 results from human head CT scans without bone tissue pathologies. To detail the craniometric characteristics of the lateral surface of the facial section of the skull, polygons (polygons) were constructed with dividing of the facial section of the skull is into the orbital-frontal, nasal, and maxillary. The facial profilegram of the skull was formed as a set of predetermined dimensions between facial profile points, presenting a continuous line passing through points gl-n-rhi-ns-pr-id-pg, reflecting the shape, dimensions, and position of the cranial profile of mature adults regardless of sex or cranial type. Results: It was established that the longitudinal anteroposterior dimensions of the facial skull exhibit a certain range of variability in mature individuals depending on gender. For instance, the distance between the points gl-po (glabella-porion) reaches its maximum values in individuals with a brachycranial skull shape, ranging from 107 mm to 130 mm in men and from 104 mm to 128 mm in women. In individuals with a mesocranial skull shape, this parameter gradually decreases to 109-126 mm in men and 107-124 mm in women. A similar decrease is observed in those with a dolichocranial skull shape, where the range is 109-121 mm in men and 109-120 mm in women. The distance between n-po (nasion-porion) in brachycranial and mesocranial individuals remains within 96-123 mm and 102-123 mm, regardless of gender, indicating that this parameter is relatively stable. However, in dolichocranial individuals, this distance decreases to 104-115 mm. Conclusions: Individual anatomical variability of the anteroposterior lateral dimensions of the facial skeleton in mature individuals has been determined. A more in-depth analysis of the existing range of individual variability in the profile configuration of the facial skull was conducted using sagittal polygons. It was found that the polygons gl-po-n, n-po-rhi, and rhi-po-ns relate to the structure of the bony profile of the orbital-temporal and nasal regions of the facial skull, reflecting the upper, combined orbital-nasal section of the head.
