[Multi-projection skull x-rays].

Abstract

An X-ray method of examination of the skull bones is discussed which is used for detecting multiple small perforating defects in the skull of various localization, determination of the localization of foreign bodies in relation to definite anatomical structures, identification of the displacement of the bone fragments into the cranial cavity, and for the diagnosis of multiple infractions of the cerebral skull. Besides two antero-posterior craniograms, radiograms were taken in additional oblique views with the head turned to the right or to the left in the interval of 20 to 45 degrees. The guiding points for the direction of the X-ray heam are: the lateral border of the superciliary arch, the midpoint between the lateral border of the superciciliary arch and the external acoustic meatus, the midpoint between the external acoustic meatus and the external occipital protuberance. The effectiveness of the method was tested on a skull phantom and verified by observations over 3 patients with multiple infractions of the skull bones.
