Chin surgery or Mentoplasty

Chin Gender


The male chin tends to be more square-shaped in men, with more pronounced and defined transitions between the chin and mandibular body, with greater bone volume and a more significant vertical dimension. Gender does not necessarily determine the position of the chin, i.e. it is possible to find retro-positioned or over-projected chins in both men and women. However, a well-defined and projected chin may improve the overall aesthetics of the jaw-chin region.


Feminization of the chin


Fortunately, the features of the chin can be greatly modified on several planes: its width, height and projection. The changes may vary depending on the anatomical characteristics of the patient and the aim we want to achieve. The type of technique used will also depend on each patients features.

For example, a sliding genioplasty technique is employed to section the chin from the front to the back, separating the chin segment from the jaw. By removing different segments we can modify height and width. The final achievement will allow us to obtain the projection or regression desired. The segments are fixed using mini-plates and titanium screws which remain unnoticeable. The incisions are closed with intraoral dissolving stitches.

In addition, a liposuction is sometimes performed to remove excess fat located under the chin, in order to obtain better definition.


Postoperative and possible complications of mentoplasty


Most patients must spend one to two nights in hospital after the surgery.

Chin compression bandage: An elasticated bandage will be placed around the chin to reduced swelling, prevent bruising and help with the healing process during the first week. After that, its use will depend on the doctor’s instructions.

Sensory changes:  Temporary numbness of the lower lip may occur, and will resolve itself in the first 3-6 months.

Work and sport:  The patient can go back to social activities 7 to 10 days after surgery, if inflammation is moderate. You must wait 4 to 6 weeks to go back to physically intensive work or practice exercise.

Infection:  Possible but very rare, if oral hygiene is maintained correctly as instructed.
