[Statistical study of the anatomo-radiologic characteristics of the sphenoid sinus and sella turcica].

On 300 human cranial radiograms (150 males and 150 females) the three dimensions and the volume of the sphenoidal sinus and sella turcica as well as the cranial diameters have been measured. The male/female differences in the mean values for each diameter and for the volumes, assayed by Student's t test, indicate a male preponderance in the case of the sphenoidal sinus. No significant correlation seems to relate the sizes of the sphenoidal sinus and sella turcica with the Cranial Index and the cranial diameters. Furthermore, no significant correlation has been found relating the size of the sphenoidal sinus with that of the sella turcica.
