Genioplasty (chin correction): procedures, costs & risks

Definition and objectives of genioplasty

The Genioplasty is a Operation to modify the structure of the chin. This can be achieved either by reshaping and Relocation of one’s own bony chins (osteotomy) or by inserting a Chin implants (Lip augmentation) take place. The aim is to Aesthetics and Symmetry to improve the appearance of the face.

Less commonly, the Chin correction primarily for functional purposes, such as in cases of congenital malformations, following trauma, or in combination with orthodontic and oral and maxillofacial surgical procedures (dysgnathic surgery) to improve occlusion.

Indications: When is chin correction advisable?

One Genioplasty is indicated for:

• Receding or small chin (micrognathia)
• Protruding or jutting chin (macrogenia)
• Asymmetries of the Chins
• The desire for improved facial harmony and a defined Profile of the face

Genioplasty techniques: bone grafting vs. implants

There are two main methods available:

Sliding genioplasty (bony chin correction)

In this context, one’s own jawbone modified:

• Access: The Intervention is usually carried out via the Oral cavity (in the sulcus between the lower lip and the gums), which causes no visible scars appear on the face.
• Procedure: The lower part of the bony chins is cut through (osteotomy) and the mobile segment of bone can then be repositioned – in the case of a receding chin, the Chin bone protruding forwards repositioned (chin augmentation); in the case of a prominent chin, it is moved backwards or the bone is worn away (Chin reduction). Corrections to the height and sides are also possible.
• Fixation: With small titanium plates and screws.
• Advantages: Versatile, endogenous Fabric, a natural feeling.

Chin implants (chin augmentation using foreign materials)

This technique is primarily used for Chin augmentation (Cheek augmentation):

• Access: This is also often discussed via the Oral cavity or, alternatively, via a small incision under the chin (submental; this results in a small visible scar).
• Procedure: A pocket is prepared in the jawbone and a pre-formed Chin implant used.
• Materials: Biocompatible materials are commonly used Implants made of solid silicone (hard silicone), porous polyethylene (Medpor) or ePTFE (Gore-Tex). Others Foreign materials Materials such as polypropylene or hydroxyapatite play a minor role in chin implants.
• Advantages: Technically, it is often simpler for simple enlargements.
• Disadvantages: For augmentation only; risks include displacement, infection (prosthetic infections), capsular fibrosis and bone erosion.

The choice of method is set out in the Consultation with the Surgeons affected. Sometimes the Genioplasty with a Liposuction in the field of Double chins combined to further define the chin-to-neck line to model.

The procedure for genioplasty surgery

1. Planning Analysis, simulation, risk awareness.
2. Anaesthesia Usually general anaesthesia.
3. Operation Duration: approx. 1–2 hours. Access via the oral cavity or submentally. Performance of the osteotomy/fixation or implant placement. Wound closure.
4. Post-operative Compression bandage/tape. Short inpatient stay or outpatient treatment.

Aftercare and recovery time following the procedure

• Swelling/bruising (1–3 weeks). Applying a cold compress helps.
• Pain management.
• Thorough oral hygiene (when accessing via Oral cavity). Soft food.
• Compression bandage.
• Recovery: Able to return to work after approx. 1–2 weeks; able to resume social activities after 2–3 weeks. Avoid sport for 4–6 weeks. Final result visible after 3–6 months. Numbness may occur (usually temporary). Avoid Nicotine is beneficial to the healing process.

Risks and complications of genioplasty

In addition to general surgical risks (infection, bleeding, etc.):

• Nerve damage (mental nerve) with numbness in the lower lip and chin.
• Bone healing disorders (following osteotomy).
• Implant-specific risks: infection (prosthetic infections), displacement, capsular fibrosis, bone resorption, visibility/palpability.
• Asymmetry, unsatisfactory aesthetic result.
• Injury to tooth roots (rare).

Coverage of the costs of chin correction surgery

The costs vary (approx. 4,000–8,000 euros). Where the procedure is performed purely for aesthetic reasons, it usually involves none Coverage by health insurance funds. Where medically necessary (malformations, following trauma, dysgnathia), a claim may be considered.
