Describe the procedure for measuring Bizygomatic Breadth and Upper Facial Height. Describe the landmarks involved
Bizygomatic Breadth (BZB) and Upper Facial Height (UFH) are important anthropometric measurements used to assess the facial morphology of human populations. These measurements help in understanding biological diversity, variation, and evolutionary adaptations. Below is the procedure for measuring both these facial dimensions and the landmarks involved.
### Bizygomatic Breadth (BZB)
Bizygomatic Breadth refers to the maximum distance between the two zygomatic arches, which are located at the widest part of the face. It is a measure of facial width.
Procedure:
1. Positioning the subject: The subject should be seated in an upright position with their head in the Frankfort horizontal plane. The Frankfort horizontal plane is an anatomical reference plane that runs from the upper margin of the external auditory meatus to the lower margin of the orbit.
