What is chin surgery?

Chin surgery is a surgical procedure aimed to change the contour of the chin. It involves either reshaping the bone itself, or increasing its size by adding a synthetic implant.

When considering surgery to change the chin, the chin itself is can be considered in isolation. Examples include a chin that is perceived as small, weak or set-back. However, chin surgery can also be considered as part of a broader rebalancing of the face. There is a harmony of facial proportions that involves balance between the chin, jaw, cheeks, nose and forehead. This balance is considered from both the front and side views. Thus, chin surgery, alone and in combination with other facial surgeries, can therefore have an effect on the overall aesthetics of the face.

Surgery that repositions the entire lower jaw can also affect the position of the chin. However, such surgery, known as orthognathic surgery, has dramatic effects on the alignment of the teeth. For this reason, it is not performed simply for aesthetics.

Surgical techniques

Surgical modification of the chin generally falls into two categories: implant surgery, and bone surgery (genioplasty). Both procedures are typically performed under general anaesthetic. Incisions are either hidden underneath the chin where it blends with the underside of the mouth, or inside the mouth near with the gum meets the lower lip.

Implant augmentation

This adds height and/or projection to alter the position of the chin point. This addition is achieved through placement of a correctly selected surgical implant, which is attached to the bone. The implants are typically manufactured out of special surgical plastics.

Genioplasty / mentoplasty

These terms describe direct modification of the chin bone. The bone of the chin point is surgically cut, repositioned to create the required contour, and then fixed in place with metal screws.

Who is a suitable candidate for chin surgery?

Chin surgery is personalized to each patient’s needs, but should stem from personal desires rather than external pressures. Candidates typically:

  • Are physically healthy and maintain a stable weight
  • Have realistic expectations
  • Are nonsmokers
  • Are bothered by their chin’s appearance, whether it’s short or lacks projection
  • Do not have significant issues with teeth alignment

What should I expect during my consultation?

During the consultation, expect discussions on:

  • Surgical objectives and expectations
  • Medical history, allergies, and current medications
  • Previous surgeries
  • General health assessment
  • Facial examination, measurements, and photographs
  • Treatment recommendations and anticipated outcomes. These may include a discussion of surgery to other parts of the face.
  • Potential risks, side effects, and the management of these

Open communication is vital during this process, allowing you to address concerns and receive clarification on all aspects of the surgery. It’s natural to feel a mix of emotions, from excitement about potential results to preoperative apprehension, and your plastic surgeon is there to support you through these discussions.

What questions should I ask my plastic surgeon about chin surgery?

  • Are you vocationally registered with the Medical Council of New Zealand as a specialist plastic surgeon?

  • Are you a member of the New Zealand Association of Plastic Surgeons?

  • Will the procedure be conducted in a hospital or office-based setting, and is the facility accredited for this type of surgery?

  • What type of anaesthesia is needed for this procedure?

  • Based on my medical history and condition, is surgery the best option for me? If so, am I a suitable candidate for this surgery?

  • Which surgical technique do you recommend for my case, and why?

  • What are the realistic expectations for the outcome of this procedure in my case?

  • What steps or lifestyle changes are necessary for me to get the best result from my surgery?

  • What is the anticipated duration of recovery, and what assistance will I need during this period?

  • What potential risks and complications are associated with this procedure? How would you manage these should they arise?

  • How will my results change over time?

  • If I’m unhappy with the outcome, what recourse options are available?
