A Slim Line from Any Angle

By analyzing your natural skeletal shape and resecting only as much as needed,
an angular face shape is made soft and slim.

Square jaw surgery

Jawline angle adjustment
considering lower-face proportions

Through mandibular angle resection and adjustment of the resection range, lower-face proportions are taken into account
to adjust the jawline angle to your face shape.

Square Jaw Surgery

Systematic Consultation and 1:1 Customized Design

Bone, fascia, fat and skin conditions are assessed with 3D CT and ultrasound
to predict even sagging and neck line changes and accurately identify the necessary correction direction.

  • 1:1 Contouring Diagnostic Consultation

    1:1 Contouring Diagnostic Consultation

    We analyze your current facial structure, problems, potential for sagging
    and the flow of the jawline and neck line from multiple angles
    to set an individual contouring direction and surgical strategy.

  • Precise 3D CT Structural Diagnosis

    Precise 3D CT Structural Diagnosis

    Based on 3D CT,
    we analyze in detail the skeletal shape that determines contouring results,
    the thickness of fascia, fat and skin, the location of nerves and blood vessels,
    and the extent of the neck line and jawline involved.

  • Structure-Based Contouring Design

    Structure-Based Contouring Design

    We design a structural flow in which the jawline, cheekbones, chin and neck line connect naturally,
    and establish a realistic correction plan
    suited to each person's structure.

Personalized Surgical Design

Considering the mandibular angle resection range and lower-face proportions,
only as much as needed is resected to create a natural line.

  • Square Jaw Resection

    Square Jaw Resection

    When the area below the ears looks wide and angular,
    the protruding mandibular angle is resected to reduce lower-face width
    and soften the side profile.

  • Long Curved Resection

    Long Curved Resection

    When the mandibular angle protrudes and the line under the jaw looks heavy,
    a resection range extending long from the mandibular angle to the chin
    is set to refine
    the flow of the lower contour in balance.

Sagging-Prevention Contour Fixation

SINSANG's own fascial structure fixation, which fixes the SMAS layer and soft tissue upward,
structurally prevents sagging below the cheekbones and along the jawline.

Dedicated Facial Contouring Team

A contouring specialist team experienced in a wide range of contouring cases
takes 1:1 responsibility from consultation to surgery and follow-up.

Facial contouring surgery:

By correcting the skeletal baseline,
we create stable contours.

Contouring design focused on maintaining lines, reflecting facial structure and tissue response

Contouring surgery does not simply reduce bone;
it realigns the center of the facial skeleton.
Rather than excessive or insufficient resection, we reduce only as much as needed and reinforce only as much as needed,
focusing on preventing sagging, loss of definition and blurred lines.

Better effect when combined with square jaw surgery!

  • Cortical Bone Removal

    Cortical Bone Removal

    The outer cortical bone is trimmed as much as possible
    to slim the face width seen from the front.

  • Masseter Reduction

    Masseter Reduction

    Unnecessarily protruding masticatory muscles are refined
    to maximize the effect of the contour line.

  • Buccal Fat Removal

    Buccal Fat Removal

    Fat in the deep soft tissue layer is removed
    for a clear lower-face line without sagging.
