Morphometric Measurement of Cranial Vault Thickness: A Tertiary Hospital Based Study

Abstract

Introduction: The skull’s main function is to protect the brain. Total skull bone thickness is the total thickness of diploe and the external and internal tables. The measurement of the human skull based on CT images results are of great practical value in the fields of anatomy, clinical medicine, biomechanics study and head injury analysis. There are few literatures about imaging assisted measurement of the cranial vault thickness while sparse literature among Nepalese population. In this study, we aim to measure the thickness of Nepalese calvarian bones and find the difference between gender and ethnic groups.Methods: This was a descriptive cross-sectional study conducted in our center during a period of 6 months. Patient of age 15 to 50 years with normal CT finding were included in the study. Using the axial view of brain CT, the thickness of cranial vault was measured and recorded in millimeter. Results: Among 100 patients, 51 were male and 49 were female. Mean thickness of frontal bone, parietal, temporal and occipital bone were 8.02±1.97 mm, 7.04±1.43 mm, 4.71±1.34 mm and 7.98±2.47 mm respectively. Conclusions: There was no significant difference in cranial vault thickness among sex or ethnical groups in patients of a hospital.

Peculiarities of the parietal bones of the vault of the human skull structure and shape, taking into account sex and craniotype

“…Classic craniometric works, which were performed using collections of skulls, usually described not only the main parameters of any bone, but also provided a certain characteristic of its shape, structural features, established the existing variability [10,12,13,15]. The parietal bone, as one of the largest structures of the cerebral part of the skull, has a significant dependence on the established craniotype, while there are certain ranges of changes in the main linear parameters, which is confirmed by the studies of a number of authors [3,16,17]. However, in modern morphology, greater attention is paid to the intravital study of anatomical structures, including the bones of the human skull, which is made possible by the use of the latest systems of instrumental research [1,2,6,8,11].…”

Morphometric Analysis of Posterior Fossa and Foramen Magnum among Pediatric Age Group 6 to 16 Years

“…Various morphometric studies considering cranial bony details have been described till date, however there is no anatomical study regarding the concerned topic among pediatric population aged 6 to 16 years in Nepal to the best of our knowledge. [5][6][7][8][9] Hence, the results obtained from this study will help in the better diagnosis, classification, and treatment of diseases related to posterior fossa and craniovertebral junction and serve as a future reference defining an anatomic range in our region. This produced a total minimal sample size of 58 participants.…”

Individual Anatomical Variability of the Thickness of the Parietal Bones of the Skull Vault of an Adult Humans

“…This bone base is one of the most important structures of the human body from the point of view of performing a variety of neurosurgical interventions when accessing intracranial formations [1][2][3][4][5]. Classical craniometric studies using cranial collections usually described not only the main parameters of any bone but also provided a certain characteristic of its shape, established the existing variability, and described the thickness in different parts and sections [6][7][8][9][10]. However, the most promising issue in modern morphology is the lifetime analysis of anatomical structures, including human cranial bones, which has become possible using the latest instrumental research systems [11][12][13][14][15].…”

“…Ця кісткова основа є однією з найбільш важливих структур тіла людини з позиції виконання безлічі нейрохірургічних втручань при проведенні доступів до внутрішньочерепних утворень [1][2][3][4][5]. Класичні краніометричні роботи, які використовували колекції черепів, зазвичай описували не тільки основні параметри будь-якої кістки а й надавали певну характеристику її форми, встановлювали існуючу варіабельність, описували товщину у різних відділах та частинах [6][7][8][9][10]. Однак, у сучасній морфології найбільш перспективним питанням є прижиттєвий аналіз анатомічних структур, в тому числі кісток черепу людини, який став можливим за використанням новітніх систем інструментального дослідження [11][12][13][14][15].…”
