Softening an angular line ANSWER Square Jaw Reduction
Contouring surgery that refines the developed jaw angle for a soft jawline and slim lower face.

ANSWER Square Jaw Reduction
Square jaw reduction cuts the developed mandibular angle and jawline bone, refining an angular lower face into a soft curve. ANSWER Plastic Surgery uses a long-curve osteotomy as standard so both the front and profile look natural, designing a safe surgical range around the nerve path and soft-tissue condition.
When Square Jaw Reduction is needed
If any of the following apply to you, we recommend a specialist consultation.
An angular lower face
A developed jaw angle makes the profile look angular and the impression strong
A wide-looking front
Wide jawbone from the front makes the face look large
Jawline asymmetry
Left–right differences in jaw development tilt the jawline
A secondary angle
A bumpy or stepped mid-jaw keeps the line from flowing smoothly
Wanting a V-line
You want a smooth line running all the way to the chin
CUSTOM DESIGN
A long curve designed for front and profile
Cutting only the jaw angle changes the profile but little of the front, and a step can leave a secondary angle. ANSWER Plastic Surgery designs a long curved osteotomy from behind the ear toward the chin, aiming to narrow the frontal width and smooth the profile line together.
- 1Osteotomy range and thickness planned precisely on 3D CT
- 2A long angle-to-chin curve prevents steps
- 3Cortical bone resection considered when frontal narrowing is needed

ANSWER POINT
Surgery centered on nerve protection and bleeding control
The inferior alveolar nerve runs inside the jawbone, so the osteotomy line is planned at a safe distance after mapping the nerve canal. The intraoral approach leaves no external scar, and intra-operative bleeding control and anesthesia monitoring keep safety central.
- 1Osteotomy set at a safe distance from the mapped nerve canal
- 2Intraoral incision leaves no visible scar
- 3Bleeding and vital signs monitored throughout surgery
- 4A conservative approach that avoids excessive resection

ANSWER Square Jaw Reduction: How It's Done
Precise Diagnosis
3D CT maps bone thickness, the nerve canal, and asymmetry.
Line Design
Frontal and profile photos plus analysis set the osteotomy range and target line.
Osteotomy
Through the intraoral approach, the jawbone is cut and refined along the planned curve.
Recovery Care
Compression bands, swelling care, staged diet, and oral hygiene are guided.
Progress Checks
Regular visits confirm bone union and recovery while the line settles.
Frequently Asked Questions
QWill my jaw skin sag after surgery?
Reduced bone volume can burden lax soft tissue, so we assess skin elasticity beforehand and adjust the resection. When needed, we also discuss skin-tightening care or supportive procedures.
QHow long until the swelling goes and I can resume daily life?
Major swelling typically eases around 2 weeks, with fine swelling resolving over months. Light daily activities often resume within 1–2 weeks, though it varies, and we guide you by your progress.
QWith an intraoral incision, how do I eat?
Start with liquids, then porridge and soft foods in stages. Rinsing after meals and oral disinfection help the incision heal, with detailed instructions provided at discharge.
