ABSTRACT
Background: Sutural bones are supranumary bones occurring along the sutures and completely surrounded bysutures of the skull. Their number, morphology and location in skull vary in skulls. The knowledge of these bonesis imperative in surgery, medicolegal cases involving child abuse or fracture of skulls and for anthropologicidentification of human populations. This study was undertaken to examine incidence and pattern of distributionof sutural bones in dry skulls from Eastern India and compare the findings with similar studies across the world.Materials and Method: 180 dry crania were identified as male or female skulls and studied for the incidence andpattern of distribution of sutural bones. Also the Cephalic Index was measured for finding its correlation withthe number of sutural bones appearing in a skull.Results: 124 skulls were identified as male and 56 as female skulls. Overall incidence of sutural bone occurrencewas found to be 72.28% which was essentially similar across sexes. The most common sites for sutural bones,in descending order of occurrence, were found to be parieto-occipital suture, asterion, pterion and lambda.Bregma was the least common site where no sutural bone was encountered. A highly statistically significantfinding was in regard to laterality of sutural bone occurrence. Sutural bones occurring along coronal, parietotemporal, parieto-mastoid, occipito-mastoid sutures and pterion exhibited more than 80% tendency towardsunilateral occurrence while those occurring at asterion exhibited around 70% tendency towards unilateraloccurrence. All these findings, although displayed variable degree of sexual dimorphism, were statisticallyinsignificant for variation among sexes. No correlation between the number of sutural bones with cephalic indexwas found.Conclusion: The findings of this study are in agreement with the findings of many similar suitably poweredstudies across the world.
ABSTRACT
@#The present systematic review explores the most sexually dimorphic parameters by using geometric morphometric analysis of human skull. An extended search was conducted in Google Scholars and PubMed (published between 2005 and 2017). The main inclusion criteria were research articles published in English, and studies that used geometric morphometric analysis for classification of human skull. The literature search identified 54 potential relevant articles whereby, five had met the inclusion criteria. Most studies reported positive contribution of geometric morphometric as an alternative and accurate tool for classification of unknown human crania. Geometric morphometric method resulted in a high classification accuracy of sexual dimorphism among different populations. Further studies are required to approach the best method used for varied types of postcranial bones equipped with a more advanced meta-analysis of the results.
ABSTRACT
Sex determination is one of the main steps in the identification of human skeletal remains. It constitutes an initial step in personal identification from the skeletal remains. The aim of the present study was to provide the population-specific sex discriminating osteometric standards to aid human identification. The present study was conducted on 87 (174 sides) slices of crania using postmortem computed tomography in 45 males and 42 females, aged between 18 and 75 years. About 22 parameters of crania were measured using Osirix software 3-D Volume Rendering. Results showed that all parameters were significantly higher in males than in females except for orbital height of the left eye by independent t test (P<0.01). By discriminant analysis, the classification accuracy was 85.1%, and by regression, the classification accuracy ranged from 78.2% to 86.2%. In conclusion, cranium can be used to distinguish between males and females in the Malaysian population. The results of the present study can be used as a forensic tool for identification of unknown crania.

Background: The deficiency in the antero-inferior wall of the bony part of external auditory canal (EAC) closes by 5 years of age but if it persists beyond that age it is called foramen of Huschke. Depending on the population studied, persistence of this foramen has been seen in 0-67% of adult crania. Review of literature revealed that no data was available in North Indian population; therefore the present study is being undertaken. Methods: Sixty North Indian adult human crania were examined and the presence of foramen of Huschke was noted. The side to which it belonged to, its shape and size were observed. Size of the foramen was measured using vernier caliper. Results: Out of sixty North Indian adult human crania seen, foramen of Huschke was present in 14 crania. It was observed unilaterally in 10 crania and bilaterally in 4. Although different shapes of the foramen like pin point, pin head, circular, irregular and U shape were observed but in majority of cases it was U shaped. Its size varied from pin point- 10 mm transversely and pin point to 9 mm longitudinally. Conclusion: This study revealed that about 23% of North Indian adult human crania have foramen of Huschke. Persistent foramen of Huschke in the adult life may be involved in different abnormalities of the EAC and may lead to otological complications. Therefore, ENT surgeons should be aware of persistent foramen of Huschke and keep it as one of the possible diagnoses while dealing with patients presenting with otological complications. Also the surgeons should be careful while performing endoscopy of Temporomandibular Joint (TMJ) so that accidental damage of TMJ can be prevented.
ABSTRACT
Durante la vida fetal y la infancia, los huesos planos de la bóveda craneal están separados por membranas densas de tejido conectivo que constituyen articulaciones fibrosas conocidas como suturas; las cuales tienen como objetivo durante los primeros estadios de la vida favorecer el desarrollo encefálico. Eventualmente estas suturas con el paso de los años se cierran formando una sinostosis entre los huesos del cráneo. Una de estas es la sutura frontal, que une los 2 huesos frontales en la época embrionaria y en el recién nacido. Esta sutura puede persistir en el tiempo generando el cuadro conocido como metopismo. Alteración que muestra distintas presentaciones e incidencias según sea el grupo étnico estudiado. El propósito de este artículo es mostrar las características que presenta esta condición, frecuencias, descripciones, variedades, etc., analizando distintas bases de datos, junto a la descripción de un caso. Se plantea la importancia que posee a nivel clínico a la hora de invadir quirúrgicamente esa zona, o la confusión que se puede presentar a nivel radiográfico lo cual eventualmente puede generar alguna complicación, por lo cual es de real relevancia el conocimiento de las bases morfológicas de esta condición con el fin de realizar un correcto diagnóstico y procedimiento quirúrgico si este lo amerita.
During fetal life and infancy, flat bones of the cranial vault are separated by dense connective tissue membranes, fibrous joints called sutures, which are aimed early on in life to promote brain development. Eventually these sutures close over the years to form a synostosis between the bones of the skull. One of these is the frontal suture, which joins the two frontal bones in the embryonic period and the newborn. This suture may persist over time, generating the condition known as metopism. Alteration showing different presentations and incidents depending on the ethnic group studied. The purpose of this paper is to show the features found in this condition, frequency, description, varieties, etc. This analysis was performed on different databases and the description of a case. It raises the importance that clinicians approaching the area at the time of surgery consider possible confusion at the radiographic level which can lead to subsequent complications. Therefore, real knowledge of the morphological bases of this condition is important for correct diagnosis and surgical procedure if warranted.

We have measured the longitudinal, transverse diameters of optic canal, foramen rotundum, foramen ovale, foramen spinosum, to serve as a handy guideline to surgeons, to enhance the accuracy of sexing the cranium for anthropometric/medico-legal studies and for comparative analyses of values of the Nigerian population with those of the Caucasians. A total of 100 adult dry skulls 81 male, 19 female from departments of Anatomy of some Nigerian Universities were used. Automatic vernier caliper with a precision of 0.1mm was used. Data analysis was performed with Graph Pad Prism 3.0. A comparison was made of the means of the dimension using Student's T-test and analysis of variance. Sizes of foramina were not significantly different from that of Caucasians Our results show significant sexual dimorphism in the following parameters, the right transverse diameter of the FR in males was found to be significantly different from the females at p<0.05, there was a significant difference between the means of the left and right sides of the foramen ovale. The distance between right ovale and spinosum in males and females was found to be significantly different in both sexes. The effect of side on longitudinal diameter of foramen ovale FO of males showed a significant difference between the means of the left and right sides of the foramen ovale. A comparism of the distance between left optical canal and foramen rotundum showed a significant difference between the values obtained for males and the females at p< 0.05.

In order to identify the sexual difference and the aging changes on the cranial metric dimensions and to clarify the anthropological characteristics of Korean skulls, authors took the radiographs of lateral skull projections and made out perspective drawings and measured 33 cranial metric dimensions using 32 standard points of normal Korean 373 heads. The results were as follows. 1. 4 items of metric dimensions on the calvarial thickness were greater in the male than the female and all the calvarial thicknesses of younger adults were thicker than the older adults. 2. As a result of measuring 11 items of skull size including the maximum cranial length (glabella to opisthocranion diameter) and the cranial height (basion to vertex diameter), all average metric dimensions of the skull were shown the sexual difference. 3. Among the metric dimensions of skull size, the maximum cranial length (glabella to opisthocranion diameter) was not different between the younger and older adults, but the cranial height (basion to bregma diameter) was greater in the younger than the older adults. 4. In according to the metric dimensions of the cranial base, the length and the angle of the cranial base were shown the sexual difference, that is, all dimensions on the cranial basewere greater in the males. 5. The breadth and height of pituitary fossa were greater in the older female than the younger females. 6. Metric dimensions on the sella position related to other cranial landmarks were shown the sexual difference, but there were no differences between the younger and older adults. 7. Metric dimensions on the frontal sinus were shown the greatest sexual difference and there were the differences between the younger and older males, not in the females. Taken all together, all the basic anthropological data of Korean crania in this study will be helpful to the sexual discrimination, and will be applied to other basic medical and dental sciences.
