MULTI
SQUARE JAW

Identifying the actual cause of square jaws, our surgery involves removing the bone, fat, and muscle to create a perfect line.

Multi-Angular Jaw
Reduction Surgery

Rather than indiscriminately reducing bone, we perform customized surgery for each individual, creating the optimal combination for a smooth jawline.

Achieving High Satisfaction with
18 Years of Research and Clinical Know-How

The Distinctive Surgical Methods of Dr. Insoo, Kirk ,
a Master of Contour Surgery Remember, insufficient clinical
experience may lead to unsatisfactory outcomes.

Precise analysis and meticulous planning are essential for this complex surgery. Dr. Insoo, Kirk ’s Multi-Angular Jaw Reduction Surgery pioneered methods that reduced soft tissue and shrunk the lower jaw area in various ways. It's not just about cutting the mandible bone to make a smaller jaw but simultaneously treating the fat layer and muscles to reduce the lower jaw area more effectively. Developed over 15 years with more than 4,500 cases, this surgery has continuously evolved and is a safe and effective method for reducing square jaws, using facial ultrasound for accurate measurement.

Multi-Angular Jaw Reduction Surgical Method

Square Jaw
Bone Resection

Removal of
Square Jaw Bone

S T E P 0 1

Mandibular Angle Osteotomy (Side and Front Effects)

We resect from the angular square jaw beneath the ear to the front jaw in a long curved shape, creating a slender face with reduced side and frontal effects. Even without surgery on the front jaw, we smoothly file down to prevent secondary angles, crafting a natural, slender V-line that appears innately yours.

Cortical Bone Osteotomy (Frontal Effect)

Reducing thickness through cortical bone resection, we remove the outermost cortical layer encasing the jawbone. This process slims the bone's thickness, resulting in a slimmer facial shape from the front.

Masseter Muscle Reduction Surgery

In cases of developed masseter muscles, we perform muscle reduction surgery concurrently with bone surgery. The amount of muscle resected is measured in advance using ultrasound and X-rays and removed during surgery. As muscle resection is a complex procedure, precise pre-surgical diagnosis and the surgeon’s proficiency are crucial.

Excessive Jaw Fat

Lipolytic Injections

Excessive Fat Dissolution and Removal

At ONUL PLASTIC SURGERY, we remove two layers of fat. The subcutaneous fat layer is treated with our unique fat-slimming injections and Accusculpt liposuction, while the deep buccal fat is directly removed, creating an optimal balance.

Distinctive Surgical Method by Dr. Insoo, Kirk , an Expert in Facial Anatomy

What is Nerve-Preserving Contour Surgery?

Nerve-preserving contour surgery, developed by Dr. Insoo, Kirk as the world's first, involves cutting only the surrounding bone without damaging the mandibular nerve.

Key Point

Typically, square jaw surgery is limited or less effective when the mental nerve, which affects lip sensation, is low. Thanks to abundant clinical experience and precise surgical planning, Dr. Insoo, Kirk successfully performs square jaw surgery without damaging the mandibular nerve, creating a small and slender jawline even for those with difficulties undergoing surgery due to a low nerve line.
