Probably thebest method to em-ploy is to centre the tube behind and a little below the angle of the jaw. Withthe plate on the injured side, the tube is centred over a spot behind and belowthe angle of the uninjured jaw, thus avoiding the overlapping of the latter. By using the above method it is possible to obtain a picture of the siderequired, showing the whole of the lower jaw in profile, the temporo-maxillaryarticulation being weft shown. This is also a useful method when it is neces-sary to examine the jaw for tumour or dental disease. Fractures of the Nasal Bones.—These are occasionally fractured onone or both sides. A plate on the injured side is generally sufficient to show.
