Genioplasty

Genioplasty involves modifying the shape of the chin so that each part of the face, seen from the front and in profile, is balanced. In profile view, the analysis is carried out in relation to the Frankfurt horizontal plane and measures chin projection. Treatment may be micro invasive, especially when only a slight increase in projection is required, or invasive, which is the only way to reduce excessive forward projection of the lower jaw.

This procedure is intended for patients who wish to correct a facial imbalance, whether congenital or related to the natural evolution of the face. Genioplasty can also be combined with other facial surgery techniques, such as rhinoplasty, to optimize overall harmony. Before any procedure, a 3D facial analysis is often performed to plan the modifications with precision.

The indications for genioplasty are varied : receding chin, overly prominent chin, or mandibular asymmetry. Analysis of the face and its proportions is always completed by an assessment of dental occlusion, which is a key element in establishing an accurate diagnosis. When dental occlusion is normal, an isolated procedure on the chin may be proposed. This may involve either an increase in chin projection using a micro invasive or invasive surgical technique, or a reduction, which can only be achieved through invasive surgery.

For patients with mandibular dysmorphosis, a multidisciplinary approach involving an orthodontist may be required. In all cases, the objective is to restore balanced facial aesthetics while preserving proper mandibular function.

Micro invasive technique

This involves augmenting the anterior projection point of the chin. This result can be achieved through injections of dermal fillers or autologous fat. A more comprehensive augmentation of the lower jaw can also be performed using hyaluronic acid injections to improve the balance of the lower face.

Invasive technique

The invasive technique modifies the bone structure of the chin. It is the only approach that allows for a reduction in projection, particularly in cases of a “protruding” or “witch’s chin.” It also allows for chin augmentation, in order to achieve a permanent result.

Nothing is left to chance : shape, symmetry, and volumes are adjusted with meticulous care.

Micro invasive technique using hyaluronic acid injections

After precise analysis of the injection points, hyaluronic acid is injected. The required volume is most often 3 to 4 ml, corresponding to 3 to 4 syringes, administered in one or two sessions. The result is immediate, with stabilization occurring after approximately three weeks. Regular maintenance is recommended. It is also possible to choose a more definitive technique at a later stage. Postoperative recovery is very simple, without pain and without any socio professional downtime.

Minimally invasive technique using lipostructure

The implanted volume is, in this case, your own adipose tissue, preferably harvested from an area of ​​excess fat (abdomen) or from the inner thighs and knees. A very small amount may be harvested from different areas to ensure no trace of the procedure is left. The adipose tissue is then purified and transferred via autograft.

This technique can be performed under local anesthesia without hospitalization, but often requires general anesthesia in a clinic for greater comfort. A period of social and professional downtime of 2 to 6 days is to be expected due to bruising that may occur on the chin and neck.

Bruising is to be expected in the donor areas.

Invasive technique modifying bone structure

This technique requires anesthesia. Access to the chin bone is achieved through the mouth to avoid any external scar. The chin can then be augmented with an implant or reduced. It is also possible to increase chin height by changing bone orientation and fixing it with micro screws. Postoperative recovery requires relative rest for about one week. The result is visible immediately, although tissue swelling alters its appearance during the first two months.

After genioplasty, postoperative recovery depends on the technique used. For micro invasive procedures, recovery is generally rapid, with moderate swelling and bruising that resolve within a few days. Patients can resume daily activities quickly, provided postoperative instructions are followed. For invasive surgical procedures, careful postoperative monitoring is necessary.

Postoperative pain is usually well controlled with analgesics, and final results become visible after several months, once swelling has completely subsided.
