Augmentation genioplasty is a surgical procedure aimed at enhancing the bony contour of the chin. This procedure can be performed using various materials, including prosthetic implants made from medical-grade silicone or other synthetic substances, as well as autogenous grafts derived from the patient's own cartilage or bone. Additionally, cadaveric allografts, which are cartilage or bone grafts obtained from a tissue bank, may also be utilized. The surgery typically involves making an incision either under the chin (submental approach) or inside the mouth (intraoral approach) to access the chin's periosteum, which is the dense layer of connective tissue surrounding the bone. During the procedure, careful dissection is performed to expose the periosteum while protecting the mental nerves located on either side of the mandible. The midline of the chin is marked to ensure proper alignment of any implants or grafts used. If a prosthetic implant is chosen, it is positioned beneath the periosteum, ensuring that it aligns with the midline of the chin for optimal aesthetic results. The soft tissues are then meticulously closed in layers to promote healing. In cases where autografts are used, they are harvested through a separate incision, shaped to fit the surgical site, and implanted similarly. Allografts follow a comparable process, being configured to the appropriate size and shape before implantation.

Augmentation genioplasty is indicated for patients seeking to improve the aesthetic appearance of their chin, particularly in cases where the bony contour is deficient or underdeveloped. The procedure may be performed for the following reasons:
The augmentation genioplasty procedure involves several key steps to ensure successful outcomes. Each step is critical to achieving the desired chin contour and aesthetic results.
After the augmentation genioplasty procedure, patients can expect a recovery period that may involve swelling, bruising, and discomfort in the chin area. Post-operative care typically includes pain management, instructions for oral hygiene, and guidelines for activity restrictions to promote healing. Patients are advised to follow up with their surgeon to monitor the healing process and ensure that the desired aesthetic outcomes are achieved. It is important to adhere to all post-operative instructions to minimize the risk of complications and support a smooth recovery.
