Genioplasty - Chin surgery

The chin, refers to the protruding part of the face. It constitutes an extension of the jaw and corresponds to the horizontal part of the mandible.

What is genioplasty?

"Mentoplasty" or "cosmetic surgery of the chin", is a technique of face surgery that brings a change in the shape of the chin that would be harmonious with the rest of the facial features.
This is an individual act and indicated for a patient whose facial bones have discomfort caused by an absence of the contour of the face, a small chin or a weak jaw.

In fact, the disgraces of the chin are of two types, namely, a clog chin or too advanced chin and a weak chin or too backward.

Preoperative consultation

The cosmetic surgeon, carefully examines the overall morphology of the face and performs an endobuccal examination.
The expected result is evaluated using photographs and computer editing that fixes the virtual image of the surgical project.

A blood test is carried out in accordance with the prescriptions.
It is recommended that the patient stops smoking for 1 month before and after the operation as well as any medication containing aspirin during the 10 days preceding the day of surgery.


The mentoplasty operation, lasts 1 hour on average under general anesthesia as part of a clinic stay of 1 to 2 days.
The cosmetic surgeon, approaches the chin through an incision on the oral mucosa, inside the mouth on the lower lip.
Then he cuts the chin below the roots of the teeth to move the bone fragment in the intended direction that would then be fixed using screws or mini-plates.

in practice, the surgical technique depends on the appearance of the chin:
The chin too elusive that would be too receding from the face using two techniques:
Plane the jaw bone, filing down the lower edge of the mandibular bone to decrease the projection of the chin.
osteotomy of the chin, cutting the excess bone and refixing the front part of the chin with plates and metal screws.

The Genioplasty of the chin too protruding which would be very prominent towards the front of the face using three techniques:

  • Install a chin implant, silicone or Medpor whose results are remarkable.

The choice of prosthesis, varies according to the aesthetic defect to be corrected and the expectations of the patient.

  • Osteotomy of advancement of the chin, by cutting the bone of the chin in the horizontal direction to create a bone fragment that would be advanced and fix in the desired position using plates and metal screws.
  • Bone graft, by taking the graft on the nose bump as part of a profiloplasty, on the skull or pelvis to reshape the chin.

Surgical follow-up

This is a little painful operation.
Bruises, persist for 1-2 weeks.
The patient, will be able to move the jaw without risk.
He must clean his teeth, by an ultra-flexible brush after each meal.
Food should be soft and avoid food that are too hot, too spicy or too acidic.


A period of 6 months, is necessary to assess the final aesthetic result of the genioplasty.
The osteosynthesis material is removed during a second operation that can be performed after 6 months of the first intervention.


The complications of this procedure, most often result from a misunderstanding related to the goals to be achieved, the occurrence of an unusual scar phenomenon or unexpected tissue reactions.

Such imperfections, are corrected by a surgical retouching that remains much simpler than the initial operation


The operation of cosmetic surgery of genioplasty, takes place in Tunisia in a renowned clinic and in compliance with international standards of quality of care for a price from 1800 euros as part of an aesthetic stay of 5 days in Tunisia, 50% cheaper than in Europe.
