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
20 Years of Research and Clinical Know-How

The Distinctive Surgical Methods of Dr. In-soo, 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. In-soo, 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. In-soo, Kirk , an Expert in Facial Anatomy

What is Nerve-Preserving Contour Surgery?

Nerve-preserving contour surgery, developed by Dr. In-soo, 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. In-soo, 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.

Two-Hour (2hour) Drain

At ONUL PLASTIC SURGERY, we perform precise and swift surgeries based on an advanced system and the rich experience of our medical staff, minimizing blood loss and often not requiring drainage in most contour surgeries.

However, in surgeries like bimaxillary osteotomy and extensive mandible reduction, some bleeding is inevitable due to blood pressure increases upon waking from anesthesia. Even a tiny amount of blood, if accumulated, can cause hematoma or infection, so we insert a drain during awakening from anesthesia. This drain exits through the intraoral incision site, eliminating concerns about scarring, and is removed approximately two hours post-surgery to minimize patient discomfort.

Pursuing Naturalness and
Facial Proportion Harmony

The essence of cosmetic surgery is naturalness.
Especially for contour surgeries, unlike general eye and nose surgeries, harmony with the overall body and facial proportions is fundamental.
At ONUL PLASTIC SURGERY, we pursue a natural facial shape that looks like it has always been yours, based on the golden ratio of the face.

Moreover, our collaboration with Seoul Asan Hospital and Seoul National University Hospital ensures even safer surgeries.

Custom Contour and Implant Surgery
with 3D Printing

Using 3D CT and 3D printing, we create actual-sized models of the current bone structure to produce 1:1 custom implants. This customization allows precise calculation of the patient's bone shape, shortens surgery time, and reduces the risk of infection from modifying the shape during surgery.
We precisely calculate to predict the post-surgery appearance, ensuring the best results.

Post-Surgery Swelling Management Program

At ONUL PLASTIC SURGERY, we assist you in returning to your daily life naturally through methods such as swelling reduction injections and management, based on the physician's assessment, to facilitate rapid elimination of swelling.

  • Swelling Reduction Injections These injections help reduce inflammation and swelling, promote regeneration, stabilize cellular membranes in surgical areas, and prevent aging and degenerative changes.
  • Swelling Management We support blood circulation, aiding in the efficient drainage of stagnant fluids and blood, proving effective against swelling and bruising.
  • Regeneration Management Post-surgery, our approach includes removing dead skin cells and sebum, soothing tired skin, and providing hydration and nutrients for skin regeneration.

Post-Surgery Scar Management Program

Scarring is a significant concern with incisional surgeries.
We spare no effort in minimizing scars throughout the surgical process, and we continue with ongoing scar injections and laser scar management post-surgery.

  • Scar Management Injections These injections aim to minimize hypertrophic scars and keloids while aiding skin regeneration
  • Pigmentation Laser This treatment prevents pigmentation at the surgical site and destroys melanin, effectively lightening the skin. It also reduces the redness of scars and suppresses excessive vascular proliferation.
  • Scar Laser Our laser treatment increases the activity of fibroblasts, promoting dermal collagen production to correct skin textures disrupted by scarring.
