Square Jaw Reduction
in Seoul
Reduce a wide or prominent mandibular angle to create a softer, narrower, and more balanced lower-face contour.
Square jaw reduction focuses on reshaping the lower jaw while considering facial width, jaw angle, chin position, symmetry, and overall facial proportions.
Square Jaw Reduction Overview
Square jaw reduction is a facial contouring procedure designed to reduce the width and prominence of the lower jaw by reshaping the mandibular angle.
The procedure is commonly considered when the lower face appears wide or angular due to prominent jawbone structure. Depending on individual anatomy, treatment may focus on the mandibular angle alone or extend along the mandibular body to create a smoother transition toward the chin.
During consultation, the surgeon evaluates jaw width, bone thickness, facial asymmetry, chin position, soft-tissue volume, and the relationship between the cheekbones and lower face.
The goal is not simply to remove as much bone as possible, but to create a balanced lower-face contour while preserving natural proportions from both the front and side views.
Because facial width can also be influenced by muscle, soft tissue, and cheekbone structure, proper diagnosis is important before determining whether square jaw reduction is appropriate.
Key Considerations for Square Jaw Reduction
Mandibular Angle
Evaluates how prominent or wide the jaw angle appears from the front and side, and whether bone reduction may improve lower-face width.
Mandibular Body
Assesses the width and contour of the lower jaw between the jaw angle and chin to determine whether additional contouring is needed for a smoother jawline.
Chin & Facial Balance
Considers chin width, projection, asymmetry, and the relationship between the jawline, cheekbones, and overall facial proportions.
What to Consider Before Square Jaw Reduction
Bone Structure & Jaw Width
The surgeon should evaluate mandibular angle prominence, lower-face width, bone thickness, and the overall shape of the jaw before determining the appropriate contouring range.
Facial Asymmetry
Differences between the left and right sides of the jaw, chin position, and facial width may affect surgical planning and the degree of correction that is realistically possible.
Muscle & Soft Tissue
A wide lower face may be influenced not only by bone structure but also by masseter muscle size, soft-tissue thickness, and fat distribution. These factors should be assessed before surgery.
Realistic Goals
Square jaw reduction can improve lower-face width and contour, but the final result is influenced by bone structure, chin shape, cheekbone width, soft tissue, and individual healing.
Square Jaw Reduction Recovery
First Week
Swelling, bruising, tightness, and discomfort around the jaw are common during the early recovery period. Chewing may feel uncomfortable, and a soft diet may be recommended depending on the surgical plan.
1–4 Weeks
Visible swelling usually decreases gradually, and many patients begin returning to normal daily activities. Temporary numbness, stiffness, or altered sensation around the lower face may still remain.
Long-Term Healing
Residual swelling and tissue changes can continue for several months as the lower face gradually settles. Final contour refinement depends on the extent of bone reshaping, soft-tissue response, and individual healing.
Square Jaw Reduction FAQ
Who may consider square jaw reduction?
Square jaw reduction may be considered when the lower face appears wide or angular due to a prominent mandibular angle or broad jawbone structure. A consultation is needed to determine whether bone, muscle, soft tissue, or a combination of factors is responsible.
Is square jaw reduction the same as V-Line surgery?
Not exactly. Square jaw reduction mainly focuses on reducing the width and prominence of the mandibular angle, while V-Line surgery may also include mandibular body contouring and chin reshaping.
Can jaw muscle reduction replace surgery?
If facial width is mainly caused by enlarged masseter muscles, non-surgical treatments may be considered. However, muscle treatment does not change the underlying jawbone structure.
Will square jaw reduction correct facial asymmetry?
It may improve some forms of lower-face asymmetry, but the degree of correction depends on bone structure, chin position, soft tissue, and the cause of the asymmetry.
When can I see the final result?
The lower-face contour becomes more visible as swelling decreases, but residual swelling and tissue changes may continue for several months before the final jawline is fully established.
