Chin Reduction (Genioplasty)

JK Magic Line Chin Reduction is a procedure that improves facial contours by adjusting the length and width of the lower jawbone when the dental bite is normal but the chin is long, wide, or blunt. Excess bone is removed through an intraoral incision, leaving no visible scar, and adjustments are made in millimeter increments while considering the balance of the entire Face.

Recommended for

· Those whose dental bite is normal but whose chin alone is long · Those with a long or protruding chin · Those with a wide jawline extending from the side jaw to the front chin · Those who want to reduce a round, blunt front chin for a slimmer contour

The KEY POINT that determines the overall impression of the Face

Before surgery → After surgery

Depending on the shape of the chin—such as a long chin, protruding chin, or short chin—the impression created by the chin may be emphasized even if the eyes or nose are attractive. JK chin surgery removes excess bone through an intraoral incision so that scars are not noticeable. Although temporary swelling may occur after surgery, the overall impression of the Face becomes more refined and harmonious.

Surgical Methods by Type

Long Chin Correction – Chin Resection

After precisely resecting the chin in millimeter increments while considering the balance of the entire Face, the remaining bone is moved inward and fixed to adjust the length of the front chin. This also creates a sharp, refined side profile.

T-Shaped Osteotomy

V-Shaped Osteotomy

Contour Shaving

Wide Chin – T-Shaped Genioplasty

For cases where the jaw is wide from the side jawline to the front chin, the front chin bone is osteotomized in a T shape and aligned with the facial midline. The angular side jawbone is then removed, and the remaining bone is brought together and fixed. This can create a slim, sharp jawline.

Mini V-Line – Front Chin Reduction

This procedure creates a V-line by reducing a round, blunt front chin when the lower jaw angles are not significantly developed. While preserving the natural side jawline, the front chin bone is osteotomized in a T shape and brought together to create a slimmer contour.
