Establishing the range of variability of the width and height of the human visceral skull depending on the craniotype and gender
(Дніпровський державний медичний університет, 2024) Melnyk, B.; Boiagina, O.; Боягіна, Ольга Дмитрівна
The range of variability of the width and height of the facial part of the human skull, depending on the extreme forms of the structure, has been established. The results were obtained, according to which the linear dimensions of the skull that we studied are directly dependent on the craniotype: the largest indicators of the width of the facial part of the skull are characteristic of euryprozops, and the smallest – leptoprozops. It was determined that the most significant difference between the above-mentioned indicators, namely their increase in men compared to women, is characteristic of advanced age and old age. There were no statistically significant differences in the width and height of the facial skull in representatives of the same sex, but different age groups. Diagrams of the ratio of various types of facial skull structure according to the main facial index were created and the most common combinations of them with types of skull structure according to the cranial index were established.
Determination of the range of variability of the human orbital opening height and width according to computer tomography data
(Дніпровський державний медичний університет, 2024) Melnyk, B.; Boiagina, O.; Боягіна, Ольга Дмитрівна; Panasenko, V.; Панасенко, В'ячеслав Олексійович
Usage of computerized tomography scanning markedly expands now the ability for studying the features of the human skull structures. Morphometric studies play an important role in the identification of a person during a forensic medical examination, in determining the features of certain anatomical structures, including the orbit. Acquired during research findings may be useful in clinical medical practice when preparing for orbital reconstruction surgery after injuries or congenital malformations. Aim of study. Establishing the range of individual anatomical variability of the height and width of the human orbital opening depending on the craniotype and gender.
Establishing the range of variability of the longitudinal dimensions of the lower jaw in women with different craniotypes

In recent years, the areas of surgery related to the correction and plasticity of the bones of the facial skull have been developing rapidly, which in turn requires indepth knowledge of the individual anatomical variability of the structures of this area. Therefore, the further study of the peculiarities of the dimensions and relationships of the skull structures remains one of the most important problems of modern craniology. The purpose of the research is to determine the range of variability of the longitudinal dimensions of the lower jaw of women depending on the type of facial skull structure.
Definition of the range of variability of the linear parameters of the human skull depending on gender and craniotype in the age aspect
(2024) Melnyk, Bogdan; Мельник, Богдан Ігорович; Boiagina, Olga; Боягіна, Ольга Дмитрівна
The question of studying sexual dimorphism, age-related changes and aging of tissues, including bone tissue, is still relevant today. The rapid development of maxillofacial surgery and orthodontics requires an in-depth study of the features of skull formations depending on gender and craniotype. The purpose of our study was to determine the patterns of sexual dimorphism of craniometric indicators of the human skull depending on age. The material of the study was 125 CT scans of the head of men and women aged 25 to 85 without pathology of the bones of the skull, performed using a Neusoft NeuViz 16 Essence 16-Slice CT Scanner System. Visual analysis and craniometric measurements were performed using the Horos ver.4.0.1 program included in the computer tomography software and the Vidar Dicom Viewer ver. 3.3.1.9. It was established that the values of the linear dimensions of the skull, such as length, width and height, depend on the craniotype and gender of the person. The range of variability of the main indices of the skull was also determined. The most common combinations of skull types have been established.
Individual anatomical variability of the longitudinal dimensions of the lower jaw in men

The issue of studying individual anatomical variability of skull bones does not lose its relevance. In order to improve methods of diagnosis and treatment of various diseases and anomalies of skull development, it is very important to have complete information about individual anatomical variability of skull structures. This necessity is primarily associated with the rapid development of maxillofacial surgery and orthodontics. For the successful treatment of the patient, one cannot do without an in-depth study of the features of the bones: their thickness, linear dimensions, craniotopographic relationships between the structures of the skull depending on gender and craniotype.
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 Вікторівна
The 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.
Planimetric analysis of individual variability and sexual dimorphism of the orbital opening
(Baltija Publishing, 2024) Melnyk, B.; Boiagina, O.; Боягіна, Ольга Дмитрівна; Panasenko, V.; Панасенко, В'ячеслав Олексійович
Morphometric studies, which are carried out using computer tomography methods, play an important role in determining the features of certain anatomical structures, including orbit. It has recently been described that aging of the facial bones is mainly a consequence of volume loss and morphological changes in the orbit, midface and mandible. Some scientists believe that age-related changes in the facial skeleton are mainly concentrated in the orbit, upper and lower jaws. They claim that the size of the orbit tends to increase with age. Toothless individuals of both sexes have wider orbit and shorter maxilla and mandible height. Thus, the problem of studying sexual dimorphism and age-related changes in skull structures, including the orbit, remains relevant.
