To have a weak or too long chin can alter the harmony of your face, but it can also have
consequences on the functionality of your organism 5respiratory, etc…). The genioplasty is
an aesthetic surgery of the chin that can modify its appearance to obtain a result that fits
with the position and the size of your forehead and your nose.
What is the genioplasty?
The genioplasty, also called mentoplasty, is a common intervention that corrects the shape
or position of the chin. The surgeon will model the lower part of the face to lean it forward
or backwards depending on the issue. This surgery technique is often indicated for people
who have a chin anomaly and who face functional issues such as respiration or tongue/lip
strap. This chin operation is often paired with a rhinoplasty (aesthetic surgery of the nose),
which will allow working on the integrality of the profile to recreate a certain harmony. This
intervention is, in this specific case, called a profiloplasty.
The genioplasty is a surgical technique recommended for people who have a chin facing
backward or forward. In this case we refer to a weak chin, a turned-up chin or a chin that is
This kind of intervention can be realized on anyone who is 16 or older. It is necessary to wait
for the facial bones to be fully developed before any type of surgery.
Chin surgery: objectives and principles
The genioplasty of reduction or advancement of the chin result in giving the face an
harmonious appearance. The final outcome aims to look as natural as possible to guarantee
the physical and psychological well being of the patient.
This surgery relies on two distinctive surgical techniques. Indeed, depending on the case, it is
possible to proceed to a bone section, also known as osteotomy, in which we put a chin
implant. The technique used for the intervention is decided jointly with your practitioner
from Clinique du Lac.
Before the genioplasty, the Clinique du Lac’s specialists take the time to see every patient to
explain the objectives and procedures of the intervention. They want to discuss everything
with the patients to understand why the patient desires such operation and to respond to
every question the patient may have.
Medical exams (radios, blood work…) are also done to allow the experts from the Clinique
du Lac to best prepare for the surgery.
Mentoplasty: type of anesthesia and hospitalization modalities
The surgical operation of the weak or turned-up chin is done under a general anesthesia, in
an operation room. The surgery lasts approximately 1h30, which varies depending on the
surgical techniques used. After the surgery, the patient needs to stay at the Clinique du Lac
for at least 24 hours.
The surgical intervention of the chin requires at first an incision by the oral mucous
membrane. This technique allows no visible scar. The surgeon will, then, detach the bone
from the dental root and fracture the bone. This allows him to move it the way he wants
(forward or backwards). It is fixed with micro screws.
If the surgeon and the patient chose a chin implant, in the case of a weak chin surgery, the
bone fracture is not necessary. A special prosthesis is then placed in the desired position and
fixed with screws. Finally, the incision is sutured with resorbable threads, which will take 2 to
4 weeks to disappear.
