Glossary:
MPA - Mandibular Plane Angle
LAFH - Lower Anterior Facial Height
CCW - Counter Clockwise
FHP - Frankfurt Horizontal Plane
Ramus height and MPA:
Gonion being lower than the Stomion when in the FHP is a good start - if it's above it then GG.
There are different factors here with overall facial length - by increasing the ramus height superficially you don't actually change the LAFH. Ramus height is basically a prerequisite to MPA - if your ramus is too short your MPA usually compensates by becoming an obtuse angle but this makes you look retarded and downgrown.

As we can see above, the ramus height changes don't affect LAFH it's only the side view - having a balanced optimum of the gonion below the stomion but above the menton - for example the 2nd and 3rd morph there.
The only way to change ramus height in affecting the whole LAFH is to either do Inverted L osteotomy, a distraction osteogenesis or total joint replacement (lol) in conjunction with bimax. These kinda treatments are used on people with severe Idiopathic condylar resorption, micrognathia or asymmetry - so for many of us here we will NOT be getting this.
For overall skull aside from LAFH superficial ramus augmentation like implants can still add to the mog. However there are issues when using implants for height such as implant reveal and dehiscence.
My proposed alternative is to achieve ramus augmentation with hydroxyapatite paste as this won't cause the issues described above.
looks natural and mogs implants (done with bimax as well)
Imo filler shouldn't be used to achieve this as it's inefficient - requires alot of it and causes a cantilever effect where filler is stacked on one another which no longer gives support as it isn't a rigid bone replicating material.
Unrelated sidenote but important to clear the matter:
For those with Long Face Syndrome or are downswung you don't actually have a big skull - you have suboptimal development. Removing bone to fix it will result in a loss of tissue support and accelerated facial aging so instead opt for anterior projection with CCW rotation.
Note how much smaller the ramus is in hyperdivergent profiles than hypodivergent - where we would expect just off the pretense of the name "short face syndrome" to have a shorter ramus than a "long face syndrome". Funny how MPA works.
Alveolar process height:
Very fucking underrated that barely anyone mentions this.
40% of your mandible height - therefore the thicker and taller this is the more LAFH you have.
How far the roots of your teeth penetrate into the alveolar process is a key indicator to this - roots that penetrate less than half into it have great vertical height and thickness whereas roots that penetrate all the way are suboptimal.
Extractions resorb the alveolar bone - bone grafts don't restore just prevent any further loss. However standard orthodontic extractions (2-4) will decrease the alveolar bone density but not significantly enough to affect LAFH. Note how her mandible ccw rotates when all teeth are lost causing a mega compact look.
Vertical Alveolar Distraction Osteogenesis - increases the height of the alveolar process by up to more than a cm but it's got a high complication rate of around 50% and is only currently done for people like the old woman above who have lost alot of alveolar bone - perhaps something to keep in mind in case you lose your teeth
Maybe in the future someone could invent something safer and better than this to augment the alveolar bone so our skulls can look like Cro Magnon or our Hunter Gatherer ancestors. Although I'm sure there are numerous other vectors to account for.

The Side-Effect Fallacy of Looks Theory and Why Gonial Angle Is Overrated
People often determine the importance of a trait by examining how much attractiveness is affected by altering the trait. E.g. by using morphs like these: People conclude, from these morphs, that the gonial angle is one of—if not the—most important factors in a jaw’s attractiveness. Wrong...
