Three anatomical contributors
- Buccal fat pad. Contributes width at mid-cheek height, which can spill toward the lower face.
- Masseter muscle. Contributes width specifically at the angle of the jaw — the visible "squareness" of a square jaw is often muscle, not bone.
- Mandibular bone. The skeletal bone itself can be wide at the angles. This is unchangeable except by bone-shaving surgery (a much larger procedure not typically performed for aesthetic alone).
How to identify which is dominant
- Photograph in front view, neutral expression. Width at cheekbones vs jaw line.
- Clench your jaw. If the visible width increases significantly, masseter muscle is a major contributor (the muscle is bulging).
- Run a finger along the lower jaw to the angle. If the bone feels prominent and angular, bone contributes; if soft tissue (muscle/fat) is what you feel, soft tissue contributes.
- Look at three-quarter view. Buccal fat causes a fullness slightly forward of the jaw angle; masseter causes squareness right at the angle.
Treatment options
- Buccal-dominant width: Conservative partial buccal fat removal. More →
- Masseter-dominant width: Masseter Botox. Reversible, maintenance every 4–6 months.
- Combined buccal + masseter: The most common reality. Combined procedures recommended. More →
- Bone-dominant width: Aesthetic surgery cannot reshape the bone without major orthognathic procedures, which are rarely justified for aesthetic alone.
