摘要
The aim of this study is the classification of the thickness of diploe, lamina externa, lamina interna and total calvarial thickness at different points of cranium in elderly men and women. In the radiology archive, measurements were made at different points in cranial MR images of 220 (110 females, 110 males) patients, the average ages of whom were 73.23 ㊣ 8.40 (age range: 61-90) and who had no disorder of the bones. Diploe thickness, lamina externa, lamina interna and total calvarial thickness were measured in eight points of the calvaria. Midfrontal point, back and front bregma, lambda, opisthocranion and euryonpoints were used in the measurement. The data was loaded to SPSS 16.0 program. T-test, Mann-Whitney U, Pearson correlation coefficient and Kruskal Wallis variance analysis were used in the statistical assessment. Results with a p value smaller than 0.05 were accepted as significant. There was statistically significant difference in total cranial thickness between males and females in the right euryon point only. Average total calvarial thickness at right euryon point was higher in females (6.20 ㊣ 0.78 mm) than in males (5.96 ㊣ 0.68 mm) (p= 0.02). Average diploe thickness was higher in female than male except for point of bregma back (p%26lt;0.05). There was positive linear correlation between diploe thickness and age except for opisthocranion, right euryon and 1cm inferior to lambda. These results related to diploe thickness and cranium thickness may be leading in the determination of sex and age; surgical interventions to the cranium and bone graft choice and may increase the reliability of the operation. El objetivo de este estudio fue clasificar el espesor del diploe, l芍minas externa e interna y el espesor craneal total en diferentes puntos del cr芍neo en hombres y mujeres ancianos. Desde el archivo de radiolog赤a se obtuvieron im芍genes de RM craneales de 220 pacientes (110 mujeres y 110 varones), cuya edad media fue de 73,23㊣8,4 a os (rango: 61 a 90 a os), quienes no ten赤an ning迆n trastorno 車seo. Se realizaron mediciones de espesor del diploe, l芍minas externa e interna, y el grosor de la b車veda craneal. Se utilizaron ocho puntos de la b車veda craneal en la medici車n: mediano frontal, bregma anterior y posterior, lambda superior e inferior, opistocranion y euryon derecho e izquierdo. Los datos fueron analizados mediante el programa SPSS 16.0. Para la evaluaci車n estad赤stica se utilizaron en las pruebas T-test, Mann-Whitney U, coeficiente de correlaci車n de Pearson y Kruskal Wallis de an芍lisis de varianza. Los resultados con un valor de p inferior a 0,
