METHOD FOR LOCATING A PATIENT'S MANDIBLE HEAD AXIS

摘要

The invention relates to medicine. The method for locating a patient's mandible head axis consists in specifying dermal points made of an X-ray contrast substance or material on a patient's skin and subsequently taking a computer tomogram in a lateral projection reflecting the above-mentioned points, and drawing, on the computer tomogram, a first line from the upper edge of the acoustic meatus to a point corresponding to the lower edge of the eye socket, from said line drawing a perpendicular line downwards passing tangentially along the rear convex edge of the articular mandible head, then drawing a perpendicular line downwards passing tangentially along the front convex edge of the articular mandible head, and a lower line passing through the neck of the joint, said line being parallel to the first line, determining a point within the outlined zone, which point is the patient's mandible head axis, and the coordinates of said point in relation to the projections of the dermal points on said X-ray photograph, and then transferring the projection of the point of the patient's mandible head axis on said X-ray photograph to the patient's skin in the area of the dermal points applied earlier.
