| Frankfort-mandibular incisor angle | Any of several variously named and variously defined anatomical angle's that have been used to quantify facial protrusion, in dentistry, the angle formed by the intersection of the orbitomeatal (Frankfort) plane with the nasion-pogonion line (inner lower angle), which establishes the anteroposterior relation of the mandible to the upper face at the orbitomeatal plane. Synonym: Frankfort-mandibular incisor angle. (05 Mar 2000) |

| Louis' angle | The angle between the manubrium and the body of the sternum at the manubriosternal junction. Marks the level of the second costal cartilage (rib) for counting ribs or intercostal spaces. Denotes level of aortic arch, bifurcation of trachea, and T4/T5 intervertebral disc. Synonym: angulus sterni, Louis' angle, Ludwig's angle, manubriosternal junction. (05 Mar 2000) |
