V-shaped Face

Square Jaw Reduction

A square jaw refers to a condition where the lower jawbone is large
and wide, causing the face to appear square-shaped.
Especially due to the angular bones near the jawline,
the face may appear larger than it actually is.

In such cases, square jaw reduction surgery can make the face appear
smaller while enhancing its three-dimensional contours,
creating a natural facial shape that harmonizes with the features
and achieves a balanced look.

Making perfect jaw line for you

The square jaw surgery at 345 plastic surgery is not an aggressive reduction surgery, but rather a procedure that preserves an appropriate amount of bone.

Aggressively reducing the square jaw does not always result in the best outcome. It is essential to minimize unnecessary removal of bone and perform a customized design that considers facial proportions. The surgery should be done safely, ensuring that the ideal, slim, and three-dimensional jawline is visible from all angles, creating an individualized, balanced appearance.

STEP 01

Long-Curve Jaw Reduction

A single curved-line osteotomy from below the ears to the chin creates a long, smooth jawline without additional bone cutting.

STEP 02

Cortical Bone Shaving

Removes the outermost layer of the jawbone (cortical bone) to achieve a slimmer facial contour.

STEP 03

Masseter Muscle Reduction

Partially reduces the masseter muscle, which is responsible for chewing, to make the face appear slimmer.

STEP 04

Buccal Fat Pad Removal

Removes deep cheek fat (buccal fat pad) to further slim the lower face.

How, Why,

Frequently Asked Questions
About Facial Contouring

There is no fixed rule for removing the screws. However, after a long period post-surgery, bone may cover the screws or plates, making removal more difficult. It is best to remove the screws (plates) after the bone has fully healed, before any bone buildup or secondary changes occur. While removal is possible starting from 6 months post surgery, our clinic typically recommend waiting around 1 year post surgery for screw removal.

Generally, when undergoing bone surgery, the reduction in bone structure causes the surrounding tissue to shrink accordingly. The time (recovery period) and degree of this shrinkage can vary depending on the individual. If a significant amount of bone is removed due to highly developed cheekbones, or if there is already sagging skin, the outcome may differ. However, it cannot be said that cheek sagging will definitely occur just from cheekbone reduction surgery.


During consultations, it is possible to predict the extent of sagging, and it is advisable to plan the surgery based on the current condition. At our clinic, if sagging is expected, we often combine the surgery with a lifting procedure, referred to as “Cheek Lifting,” (Zygoma) to address this concern.

Orthodontic treatment can generally begin about 1 month after facial contouring surgery without any issues. During the first month post-surgery, you are in the recovery phase, and actions like opening your mouth or chewing may be uncomfortable and different from before the surgery, so caution is necessary.


Additionally, surgeries such as cortical bone removal or masseter muscle reduction may be performed simultaneously, causing the surgical areas to become tightly healed. As a result, opening the mouth may not feel as natural. If you are considering orthodontics, it’s recommended to first go through the recovery process for about a month. Since recovery times vary among individuals, it’s important to consult with an orthodontist to determine if you can proceed with treatment based on your current condition.

There is one important nerve to be cautious of during cheekbone surgery—the infraorbital nerve, which is responsible for sensation in the front cheekbones, lips, and gums. Depending on the dissection area, the nerve may be slightly stretched, which can lead to a temporary decrease in sensation in the affected area.


However, as long as the nerve is not cut or severely damaged during the surgery, sensation will gradually return over time, so there is no need to worry.
