Genioplasty is a bone chin cosmetic surgery. The procedure tends to modify the morphology of the front portion of the mandible, in order to obtain a more harmonious chin. It can be associated to bone based surgery of the maxilla that aims to correct malformations of the teeth skeleton which has to be discovers before a chin surgery (class 2 or 3 of angle)
There are 2 major types of genioplasty:
-The advanced genioplasty which allows the treatment of a receding chin often causes an associated cervical relaxation. In order to obtain the expected effect, we need to cut the lower edge of the mandible, and move it forward just few millimeters then stabilize the whole part by using small titanium screws. To move the chin even more, we can use a porous polyethylene implant (Medpor) which consequently increases the volume and the projection of the chin
-The backward genioplasty: it will allow the correction of a too long and too high chin. It necessarily implies to cut the bone of the mandible in order to move backward.
The scar is hidden inside the bottom lip or under the chin, in particular during a cervico face lift.
A facial scanner with 3D reconsctruction will be required before the procedure to model the procedure. The procedure is often practiced under general anesthesia, but can be also considered under neuroleptanalgesia (local anesthesia further by tranquilizers administered intravenously) in case of simple acts (placement of an implant under the chin). This will require a pre anesthetic consultation, at least 48 hours prior the procedure. In most of the cases, the procedure is practiced under ambulatory hospitalization (entry at 08:00am and leaving at 07:00pm on the same day). The placement of an implant is not very painful. The osteotomy can cause an important swelling of the face which can be painful for the 3 following days. We should consider 5 to 7 days interruption of work after a genioplasty.
We tend to minimize the complications of genioplasties. Therefore, we favor the placement of Medpor implant under the chin for genioplasty augmentations. There is several reasons that leads us to make this choice:
-Hide the scar under the chin limits the risk of infection compared to a scar hidden in the mouth
-There are no risks of damaging the insertions chin muscles and to cause a falling chin
-We can work more precisely the sides of the mandible without risking to damage the lower dental nerves.
-The Medpor implants are fixed by titanium screws and cannot move like silicone implants
-The Medpor implant has great tissue integration and a very low rate of a capsular contracture.
What are the potential complications of a genioplasty?
The genioplasty is a delicate surgery which required a rigorous technique from the surgeon if he wants to obtain a harmonious chin. The most frequent complication is a decrease of sensitivity of the bottom lip as the dental nerves stretch. This is usually transitory (less than 3 months) but can be inconvenient.
There is also complications due to the used implants (titanium screws, Medpor implant)
At least, post operative edema can be consequent and can lead to a social eviction of more than 7 days.
What are the other procedures that could be associated to genioplasty?
Above all, rhinoplasty. This association is quiet frequent as we often see patients with a prominent nose and a receding chin. We qualify it as a profile-plasty which restores the balance of the face. We often associate genioplasty by implant to a cervico face lift. In fact, patients with a receding chin often have a relaxed neck because their jaw does not tighten the muscle enough. A chin implant allows to correct the phenomenon and to improve in a spectacular way the effect of a cervico face lift. At last, in some cases of moderate cervical relaxation, we can associate a liposuction of the neck to a genioplasty by implant. The neck is tighten again only with a small scar located under the chin without a crevice face lift.
Is there any genioplasty taken care by the national insurance?
Yes, some cases associated to an abnormality of the bones bases and the articulated dental (class 2 and 3 of angle) can be covered by the national insurance. An orthodontic treatment is necessary before hand. Our additional fees are between 2000 to 3000€ according to the difficulty of the case.
How much costs a genioplasty?
If it is just a cosmetic surgery, the total cost varies from 3500 to 4500€
If it is an act associated to another cosmetic surgery procedure, the genioplasty will cost an extra 2000€.
