Reducing the chin to fit your facial proportions
for a slim, balanced face

Chin Osteotomy: What Is It?

A small, slim facial line with the chin osteotomy that suits you!

The V-line of the face is largely determined by the tip of the chin. Because many nerves pass through the chin, the surgery calls for the skilled technique and know-how of a specialist, with delicate and meticulous adjustment of the length and width of the chin tip.

  1. 01A long chin tipand a well-developed lower jaw
  2. 02A wide front chinthat looks blunt

Chin Osteotomy Surgical Methods

There are two methods, depending on the condition of the front chin.

Case 01.

When only the front chin is long

In T-osteotomy, the bone of the front chin is cut in a T shape and brought together.

Case 02.

When the front chin is blunt and there is a square jaw

A surgical method that combines T-osteotomy with square jaw reduction, which removes part of the square jaw.

Weak Chin: What Is It?

A weak chin (receding chin) is a condition in which the chin tip does not project forward enough, making the lower part of the face look small. It may be that the entire lower jaw is small, or that only the chin tip is small. A small lower jaw overall is very rare, and improving the chin with implants or surgery to create a V-line is called weak chin surgery.

Weak Chin Self-Check

  1. 01When you look in the mirror, your chin looks pushed back.
  2. 02Your lower jaw is short, so it blends into your neck with no clear boundary.
  3. 03Your mouth doesn't actually protrude, but it looks like it does.
  4. 04Your lips protrude relatively, so your side profile isn't flattering.

Weak Chin Surgical Methods

A weak chin is corrected in three ways.

  1. 01

    Chin Osteotomy with Advancement

    The chin tip bone is cut horizontally, advanced forward, and fixed in place with metal bone pins or bone screws.

  2. 02

    Implant insertion

    An implant of a size and shape suited to the individual, such as silicone, Gore-Tex, or an artificial bone called Medpor, is inserted through an incision in the mucosa inside the mouth.

    Fillers

    When the chin looks weak because the chin tip lacks volume, this method corrects it by adding volume to the front chin with filler injections.

Weak Chin Candidates

The position of the chin tip shapes the impression of the entire side profile.

  1. 01 Your chin is recessed, so your mouth looks relatively protruded
  2. 02 Your face looks flat
  3. 03 At the chin tip, the line boundary is unclear
  4. 04 Your upper teeth cover your lower teeth, making your chin look recessed
