Craniometrical Characteristics of the Parital Bones of the Human Skull Vault With Different Gender and Craniotype

Abstract

Abstract. The constant development of modern neurosurgery and the increase in requirements for the performance of surgical approaches carried out through the bones of the skull vault lead to the formation of new requests to morphologists regarding the detailing and clarifi cation of the craniometric characteristics of any structure of the bony base of the head, including the parietal bones, as one of the largest and form-forming elements of the entire skull. The purpose of our study is to establish the craniometric features of the parietal bones of the skull of an adult human, taking into account gender and certain types of craniotype. The study was performed on 82 bone preparations, including isolated parietal bones, as well as 48 tomograms obtained during the examination of patients. The basic principle of establishing a craniotype is the calculation of the cranial index, which allows classifying anatomical objects according to the shape of the head structure. For statistical analysis, we used Statistica 13.5.0.17 (trial version) and Microsoft Excel of the MS 365 corporate package. In order to identify the existing craniometric features of the structure of the parietal bones, data on the length and width of the bone were obtained, a statistical analysis of these parameters was carried out, the craniotype of each object was established, existing patterns were established and inherent ranges were described.
