Genioplasty, also known as chin surgery, is a cosmetic surgical procedure aimed at reshaping the chin to enhance facial harmony. Commonly now planned using VSP (Virtual Surgical Planning) to maximize an aesthetic result, it involves either augmenting or changing the size and shape of the chin by altering the bone structure underneath:

Indications for Genioplasty:

1. Receding Chin (Microgenia): To enhance a weak chin and improve facial balance.

2. Protruding Chin (Macrogenia): To reduce a prominent chin and create a more proportionate appearance.

3. Asymmetrical Chin: To correct chin asymmetry caused by congenital conditions, trauma, or previous surgeries.

4. Jaw Misalignment: In conjunction with orthognathic surgery to address bite issues.

5. Facial Trauma Reconstruction: To repair and reshape the chin following an injury.

Procedure Types:

1. Sliding Genioplasty: The surgeon cuts a portion of the chin bone and moves it forward, backward, or reshapes it. The bone is then fixed in place with screws and plates.

2. Chin Implants: Synthetic implants are used to enhance the chin’s projection. These can be made from various materials like silicone or Medpor.

Drawbacks and Risks:

1. Infection: As with any surgery, there is a risk of infection at the incision site or deeper within the tissues.

2. Nerve Damage: The surgery involves working near the mental nerve, which can lead to temporary or permanent numbness in the lower lip and chin.

3. Scarring: Visible scars may occur, especially if an external approach is used.

4. Implant Issues: If implants are used, there is a risk of implant displacement, rejection, or the formation of scar tissue around the implant.

5. Bone Resorption: In sliding genioplasty, there is a risk of bone resorption where the bone may lose density or volume over time.

6. Asymmetry: Achieving perfect symmetry is challenging, and some degree of asymmetry may persist post-surgery.

7. Prolonged Swelling and Bruising: Recovery involves significant swelling and bruising, which can last several weeks.

8. Anesthesia Risks: As with any surgery requiring general anesthesia, there are associated risks, including reactions to the anesthetic.
