chin surgery or genioplasty

The chin varies widely between males and females, so it can be extremely important in gender recognition. Chin recontouring is often combined with a jaw reduction and is seen as an important part of Facial Feminization Surgery.

Gender of the chin

Female chins tend to merge together toward the center of the chin. Men’s tend to have two points directly below the canine teeth and a flat part between the points. This makes men’s chins look fuller and more square. Women’s tend to be more tapered.

Male chins also tend to have more vertical height, with more space between the lower lip and the base of the chin.

In some cases, male chins have a vertical crease in the middle, usually known as ‘cleft chin’, something that is highly unlikely for women.

Male chin

  • Square appearance
  • Higher

Female chin

  • Tapered appearance
  • Less high

Chin and facial harmony

While tastes do differ, there are a number of guidelines as to what the characteristics are of an aesthetically pleasing face. In profile view, the face should have a slight degree of convexity. With this we mean it should have a specific angle.

The profile of a patient can be significantly altered with a genioplasty (chin recontouring surgery). This, in turn, has a significant effect on overall facial harmony.

Feminizing the chin

Luckily, the chin is an area whose features can all be modified: height, width and if necessary even projection. It is possible to make various modifications to a chin depending on the individual anatomy of each patient, and the desired result. This chin recontouring surgery is called a “sliding genioplasty”.

  • General anesthesia.
  • Incision—Incisions are all made intraorally, so there will be no scars visible on the outside.
  • Sawing—The chin is cut from back to front on both sides with a saw, separating a horseshoe-shape of bone.

  • Width reduction—The middle part of the horseshoe-shaped bone can be removed to make the chin more pointed.
  • Chin advancement or setback—The final position of the piece of bone is chosen. At this point, the chin can be moved forward or backward.
  • Fixation—The bone parts are fixed using titanium mini plates and screws, which will never be removed.
  • Suturing—The wound is closed with self-dissolving stitches.


  • Hospitalization—Most patients will spend one night in the hospital after their surgery.
  • Compression Bandage—A bandage will be put over the chin to reduce hematoma. It can be removed the next day.
  • Swelling—The swelling is comparable to the swelling after jaw surgery.
  • Numbness—Most patients experience temporary numbness.
  • Work and sports—If you don’t mind being seen with the swelling, you may be able to return to your social activities 7 to 10 days after the surgery. You will have to wait until the fourth week before doing any hard work or physical exercise.


  • Infection—Infections are possible but rare.
  • Numbness—Partial numbness of part of the jaw because of mental nerve damage is rare but possible.
  • Asymmetry—Even though the surgeon is very careful marking the areas he is going to operate, there may be asymmetries. They can always be corrected afterward.
