Diagnosis of fractures of the head and neck with the aid of cylindrical pantomograms taken with a new device.
The use of cylindrical image layers in pantomographic roentgen diagnosis of fractures of the middle third of the face and base of the skull, is presented. Three dimensional pictures are presented from the horizontal, backward tilt (retroversion) and forward tilt (anteversion) projections as well as the projection of the base of the skull, which yield most information. Of these, the horizontal projection may be considered to be the projection which provides the best basic picture of the middle third of the face. The backward tilt projection reveals the bone structures of the central area and fractures in them best. Fractures in the lateral region are best seen in the forward tilt projection. The radiography of the base of the skull and the lateral walls on one film also presents a new application of the pantomographic technique. The positions of the patient used in taking these roentgenograms with a new pantomographic device developed for patients in a horizontal position are explained, and photographs of them presented. The future aims of this investigation series are referred to in the discussion.
