[Structure of the jugular fossa].
In 111 skulls and in saw-cuts of 119 pairs of the temporal bones of persons belonging to various age groups, age and individual changeability of the volume, form, thickness and foramina in the wall of the jugular fossa have been studied. During the postnatal period the jugular fossa increases in its volume twice and average meaning of its volume predominates on the right in the all age groups. The deepest place of the jugular fossa in more than half cases is displaced backward and laterally. The jugular fossa wall in the area of the inferior wall of the tympanic cavity is less thick on the right than on the left side. The foramina in the inferior wall of the tympanic cavity are found in mature persons in 6%, on the right 3 times as often as on the left; in children of younger age--in 45% and on the right more than 2 times as often as on the left.
