Square Jaw Reduction

This procedure reshapes the frontal and side facial contours by removing the prominent mandibular angle (side jaw). Based on 3D-CT analysis, long-curve osteotomy to reduce secondary angles is performed as the primary technique, with cortical bone reduction, masseter muscle reduction, and Buccal Fat Removal added as needed.

Makes an overly prominent Jaw Angle look natural and slimmer from every angle.

Recommended for

· Those concerned about a wide Jaw Angle · Those whose Face appears excessively wide · Those whose angular Face gives a harsh impression · Those with a severely angular jawline below the ears · Those who want a slimmer face shape

What Is Jaw Angle Surgery?

This procedure creates a slimmer facial contour from the front by removing the side jaw area (mandibular angle) extending from behind the ear to the chin. The ideal jawline is designed through a comprehensive consideration of not only the size and thickness of the jawbone, but also the muscle (masseter muscle) and Soft Tissue (buccal fat). · Causes of a prominent Jaw Angle: congenital overdevelopment or development of the jaw muscles due to dietary habits

A Perfect Face From Every Angle

To prevent secondary angles, the jawbone is smoothly resected from the angle below the ear to the chin according to each individual's Face. Rather than reducing only the jawbone, Soft Tissue is also considered to achieve more satisfying results.

What Is a Secondary Angle?

A secondary angle is an unnaturally angular jawline that can occur when the jawbone is resected in a straight line. Precise design through 3D-CT analysis and a long-curve osteotomy technique help prevent secondary angles and create a natural V-line.

Wonderful Jaw Angle Surgery POINT

Point 1. Detailed Preoperative 3D-CT Imaging

Before surgery, 3D-CT is used to precisely analyze tissues such as the facial bones, muscles, fat, and skin. Based on this analysis, an ideal Facial Contouring Surgery line suited to the individual Face is designed for accurate and systematic surgery. · Three-dimensional analysis of facial bone structure · Customized surgical plan according to individual concerns · Identification of nerve pathways and precise resection areas

Point 2. Optimal Surgical Methods for Natural Curved Lines

1. Long-Curve Resection

The wide jawbone is resected in a long curve from the mandibular angle below the ear, creating a natural curved jawline without secondary angles.

2. Cortical Bone Resection

The cortical bone, the outermost layer of bone at the jaw below the ear, is resected to maximize a slimmer jawline from the front.

3. Masseter Muscle Reduction

The bulging masseter muscle in the molar area is reduced to enhance the V-line effect with a natural jawline.

4. Buccal Fat Removal

Buccal fat located deep within the cheeks is removed together to reduce facial fat as well as contour the facial bones, completing a slimmer V-line.

Pre- and Postoperative Precautions

Before Surgery

· Fasting before surgery: Do not consume any food or drink, including water, candy, and gum (8 hours for general anesthesia; 6 hours for sedation anesthesia). · Please stop taking aspirin-based medications, hormonal medications, herbal medicines, and supplements 7 days before surgery. · Please avoid alcohol and smoking from 7 days before your scheduled surgery date. · Please remove all manicure and gel nails, including nail accessories, before your visit. · On the day of surgery, shower and wash your Face, then come without makeup or contact lenses, after removing jewelry, and wearing comfortable clothing that is easy to change out of. · You cannot drive yourself on the day of surgery, so please use a taxi or public transportation. · Please inform us in advance if you have medical conditions such as hypertension or diabetes, allergies or adverse drug reactions, medications you are currently taking, or implanted medical devices such as a defibrillator.
