摘要
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%26apos;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%26lt;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%26lt; 0.05. Hemos medido el di芍metro longitudinal y transversal del canal 車ptico, agujero redondo, el agujero oval, agujero espinoso, para que sirva como una gu赤a 迆til para los cirujanos, para mejorar la exactitud de la determinaci車n del sexo del cr芍neo para estudios antropom谷tricos y m谷dico-legales y para realizar an芍lisis comparativos de valores de la poblaci車n de Nigeria con los de la raza blanca. Fueron utilizados 100 cr芍neos adultos secos 81 cr芍neos masculinos, 19 femeninos de los departamentos de Anatom赤a de algunas Universidades de Nigeri. Se utiliz車 un calibrador vernier autom芍tico con una precisi車n de 0,1 mm. Los datos fueron analizados con el gr芍fico Pad Prism 3.0. Se realiz車 una comparaci車n de los medios de la dimensi車n utilizando T de Student y el an芍lisis de la varianza. Los tama os de los agujeros no fueron significativamente diferentes de la de los cauc芍sicos. Nuestros resultados muestran dimorfismo sexual significativo en los siguientes par芍metros, el di芍metro transversal del derecho de FR en los hombres result車 ser significativamente diferentes de las h
