It's time to add another chapter of brutal blackpill to the jaw surgery database. This is all about jaw angles and jaw width.
The preferred jaw angle has these characteristics: 130° in face profile view, intergonial width similar to facial width, vertical position in frontal view at the oral commissure or at least not below the lower lip, jawline slope in the face frontal view nearly parallel to (with a maximum 15° downward deviation from) a line extending from the lateral canthus to the alare, ascending ramus slope 65°–75° to the Frankfort horizontal, and curvature in the oblique view visible from earlobe to chin and not pointy.

But what if your jaw looks like the example on the left side and you aim for a look like on the right side ?
This guy had fillers, but generally, after only after a few weeks, they start to migrate, dissolve and lose contour. Additionally, they are very prone to look unnatural:
Just look at this after
It turns out that it's necessary to take a look at the underlying scelettal situation. What makes a jaw wide, angular and aesthetic from the front are mainly:
- Width and shape of the jaw angle i.e. shape and thickness of the posterior corpus mandibulae that connects to the ramus
- Position and size of the masseter muscle and the medial pterygoid muscle
A narrow, unaesthetic jaw, with blunted, rounded jaw angles, which reeks of micrognathia and other illnesses is often the result of posterior mandibular hypoplasia that is expressed by a severe lack of posterior lateral growth of the corpus mandibulae, malplacement of the ramus or TMJ issues.
When we look at this example, we find relatively normal TMJ to dentoalveolar arch vectors which indicates that this patient has a narrow jaw due to posterior hypoplasia and not because of TMJ problems. This is the most common cause of a rounded jaw:
Red line: The vector
Blue circle: Lack of bony mass
So lets talk about solutions. In my opinion, implants are unfavorable for young patients, silicone because of the infection and erosion risk, medpor because of tissue ingrowth, unsatisfactory ossification, titanium because it doesn't interact with the body AT ALL and can cool down dangerously in cold wheater and HA paste well because it usually looks like shit and has other issues. It's literally bone or death.
The patient above already got a chin wing which mainly increased mid mandibular width, but also some posterior width as shown below:
However, unfortunately, the jaw angles tend to get lost during this procedure as shown below:
Reconstruction and replacement of the jaw angles and masseter muscles is therefore needed as shown in this surgical simulation:
This is the so called side wing. It should add anything between 8 - 14mm bigonial width, reshape and accentuate the jaw angles and reposition the masseter muscles.
However, in some cases this will not be enough, and in some cases an aggressive side wing might produce unfavorable outcomes. In that case, a BSSO can help (narrow jaws are almost always recessed so you'll need this anyways probably)
The red circles show the consequence of ramus widening with a BSSO, around 4 - 6mm per side. Combined with a side wing it could add almost 25mm wigonial width.
There's a guy from jawsurgeryforums who had a chin wing and side wing, plus very little fillers done. This is his before and afters:
If it hadn't been enough, he still could have gotten the BSSO.
To sum this up:
- A narrow jaw with inward tilted jaw angles is best fixed with a chin wing, side wing, BSSO and some fillers on top.
- Young people should stay away from implants.
- And additional information: IMDO doedn't accentuate the jaw angles, it just makes the whole jaw wider which is not desired.
Therefore the promoted approach is the ONLY approach that is LEGIT, and LONG TERM SAVE.
