The "magnification sign" of triple mandibular fracture.
A new sign which can be readily detected in a standard postero-anterior projection of the mandible is described. It indicates that there are fractures of both mandibular necks and the horizontal ramus near the mid-line. There do not appear to be any situations in which a false positive sign is produced.
