Square Jaw Reduction
from 1,300,000 KRW* VAT Not Included
This square jaw reduction procedure reduces the visible width of the jaw from the front by resecting not only the mandibular angle but also the lateral surface in a single oblique line from below the ear toward the chin tip. It minimizes secondary angles and step deformities through a smooth, borderless reduction and prevents postoperative soft-tissue sagging by repositioning the periosteum superiorly.
Surgery Overview
The Oblique Osteotomy Square Jaw Reduction is MADEYOUNG's Square Jaw Reduction procedure that removes not only the mandibular angle but also the side surface in a single oblique cut from below the ear toward the chin, reducing the jaw width visible from the front. By reducing the area without a demarcation line, it minimizes secondary angles and step deformities, while superior repositioning of the periosteum helps prevent postoperative Soft Tissue sagging.

Maximized frontal effect · KNOW-HOW 1. Maximize the frontal effect with oblique osteotomy · KNOW-HOW 2. Reduce without demarcation lines: NO secondary angles or step deformities · KNOW-HOW 3. No skin sagging through periosteal repositioning
Recommended for
· Those whose Face appears wide from the front due to a Jaw Angle · Those who want a smaller, slimmer Face not only from the side but also from the front · Those concerned about secondary angles or step deformities · Those concerned about sagging skin around the jaw after surgery
The secret to a frontal effect: Oblique osteotomy

MADEYOUNG's Oblique Osteotomy Square Jaw Reduction utilizes Director Seo Beom-shin's proprietary technical expertise and Facial Contouring Surgery know-how to create a smooth resection from below the ear to the chin. It maximizes the frontal effect by reducing not only the lower angle of the Jaw Angle but also the broad side surface in a single oblique cut.
Features of Oblique Osteotomy Square Jaw Reduction
Point 1. Maximize the frontal effect with oblique osteotomy
Reduction through oblique osteotomy from below the ear to the chin can create a smaller, slimmer Face not only from the side but also from the front.
Point 2. NO secondary angles or step deformities
By reducing not only the lower angle of the Jaw Angle but also the broad side surface at once without a demarcation line, secondary angles and step deformities are minimized.
Point 3. Prevent skin sagging through periosteal repositioning
To allow the remaining tissue to settle properly after Facial Contouring Surgery, the periosteum is repositioned superiorly onto the bone to prevent unnecessary scar tissue and tissue sagging. This helps ensure that MADEYOUNG Square Jaw Reduction does not cause Soft Tissue sagging.
Different reduction areas produce different frontal effects
