Even if you have large, well-balanced facial features,

if both sides of the jawline are angular, the face shape can stand out more.

People who are troubled by a severe square jaw often choose to cover the jaw with their hair,

but in that case, it becomes inconvenient because they cannot tie their hair up, and they also have to worry when the wind blows.

What is the difference between procedures and surgery?

Many people try contour injections or Botox to reduce the burden.

However, while these procedures may help improve muscle or fat,

if the cause of the square jaw is bone, it is difficult to solve the problem at its root.

📌 When the cause is bone, it is better to consider square jaw reduction surgery.

A surgical approach that values naturalness

Square jaw reduction surgery is not simply a procedure to reduce the size of the bone.

What matters is preserving the face's natural curves

while carefully protecting the nerves and blood vessels around the jawbone.

🔎 Through preoperative CT scans and detailed examinations,

the internal bone structure and the location of the nerve line are identified before planning the surgery.

In addition, to enhance the frontal effect, cortical bone reduction to reduce the thickness of the jawbone may be performed together.

Why choosing the medical team matters for square jaw surgery

☑️ Square jaw reduction surgery requires general anesthesia.

☑️ It is a high-difficulty surgery that involves bone, which is why extensive surgical experience is important.

☑️ To expect natural results, not only the facial bones but also the muscles and fat must be considered.

An experienced medical team can analyze facial contours from multiple angles,

and carefully plan the surgery according to each person's bone structure.

☑️ Special equipment is used to prevent damage to facial blood vessels.

☑️ After surgery, a drain is worn for 1 to 2 days to remove unnecessary fluid and help prevent inflammation and aid recovery.

Safety and recovery, both require careful attention

It is important to carefully manage the recovery process after surgery as well.

Depending on the individual's condition, it is necessary to receive sufficient guidance from the medical team

and recover safely.

If you are concerned about a square jaw, rather than deciding on surgery unconditionally,

it is important to first identify the exact cause and find the method that suits you.

We hope you achieve safe and satisfying results through professional consultation and thorough examinations.

※ Depending on the individual, side effects such as inflammation, bleeding, and nerve damage may occur, so sufficient consultation with the medical team before surgery is necessary.
