Ramus
The vertical branch of the jawbone; a long ramus supports a defined, wide lower face.
The ramus is the vertical part of the mandible running from the gonial angle up to the jaw joint. A long ramus gives vertical support to the lower face, contributing to a wide, defined jaw and good facial proportion. A short ramus can make the lower third look compressed and the jaw weak even with a decent gonial angle.
Ramus length works with gonial angle and chin projection to determine the overall strength of the lower third — one of the three regions every PSL analysis weighs.
Why does ramus length matter?
A longer ramus supports a wider, more defined lower face and better vertical proportion.
Can you lengthen the ramus?
Only surgically. It is a fixed bone dimension after growth.
