Chin Surgery / Mentoplasty

Chin Surgery / Mentoplasty


The shape of your face is often identified as the thing that makes you “beautiful”, and having an overly small or recessed chin, or an oversized or overly prominent chin can affect the rest of your facial features. This is where chin surgery (or mentoplasty) comes in. There are two types – augmentation and reduction. Chin augmentation is generally used to rectify what is considered to be a “weak” chin where the patient feels it does not balance with the rest of their face, whereas a chin reduction is more often used for patients who have an overly prominent chin and want to create a more subtle contour and profile.


If you come to Géniale for a mentoplasty procedure you’ll be in the incredible hands of Dr. Bill Lyon. An Australian born and trained cosmetic surgeon, he has trained at Flinders University, undertaken extensive surgical training throughout both Australia and England, won numerous prizes and scholarships for both clinic and research work, and has numerous publications in international peer-reviewed journals. Dr. Lyon has also travelled to both Rwanda and Fiji as a part of the Open Heart International humanitarian agency. Dr Lyon’s gentle and caring approach will provide you with an honest opinion regarding your suitability for mentoplasty, with your safety and wellbeing at the core of every decision.


Here at Géniale, we will take the time to discuss a holistic approach to your goals for reshaping your body. A preliminary consultation is encouraged so you can get to know our team, and so that our resident mentoplasty specialist can assess the proportions of your entire body, not only your face, to ensure your results are as natural as possible. We also encourage consultations so you can learn more about alternative procedures that may be better suited to your goals.


There are two different types of mentoplasty procedure:

Chin Augmentation:
A chin implant is generally performed as a day procedure but depending on the patient may also require an overnight stay. The procedure involves an incision being made either inside the mouth or in the natural crease of the chin or just under the jaw to insert the implant. Chin implants come in various shapes and sizes and can even be designed to specifically suit the patient. If you’d like to bring a reference image of a chin or profile that you admire to your consultation, Dr Lyon will be able to discuss with you whether or not this is a viable option, and what other options you may have.

Chin Reduction:
A chin reduction procedure involves removing chin bone and/or surrounding chin muscle. Incisions for this surgery are usually made inside the mouth and has the surgeon breaking the jawbone in several places whereby the bone is fused together into its new position. It can result in a smaller and more aesthetically pleasing chin and jawline.

While all of our surgeons are highly trained to ensure that any undesirable side effects are minimal, there are
still inherent risks associated with this procedure. These include:

  • Anesthesia risks
  • Bleeding
  • Infection
  • Poor wound healing and skin loss – Persistent pain – Unfavorable scarring
  • Prolonged swelling
  • Skin irregularities and discoloration – Unsatisfactory results may include: asymmetry, unsatisfactory surgical scar location and unacceptable visible deformities at the ends of the incisions. (It may be necessary to perform additional surgery to improve your results)

*Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.

Is it right for me?

We understand how difficult the decision is to undergo any medical procedure. During your preliminary consultation we will assess your suitability for a mentoplasty procedure and discuss with you how best to achieve your desired result.

How long is the recovery time?

We recommend taking at least a week off of work to properly allow your body a chance to heal. As well as this, we recommend refraining from any strenuous exercise for 3-4 weeks post-procedure.

Will there be any scarring?

While our Géniale team are highly trained to reduce both bruising and scarring, these are a natural side effect of this procedure. Bruising and swelling will be present post-procedure but generally fades within 14 days. Scarring is dependent on the location of your incisions. If this are placed within the mouth, then scarring will be out of sight. If your incision is made under the chin then there is often scarring, however this is minimal and will fade with time.

Will I need anaesthetic?

General anaesthesia is a requirement for a mentoplasty procedure. While the risks of modern anaesthetic are low they are still present. The doctor will discuss these with you prior to the procedure.

How long until I see results?

Results will be immediate and will continue to improve for 3-4 weeks. This continued improvement will take
place as the swelling and bruising from the procedure begins to fade.

Will other medications affect results?

Our Géniale doctors will enquire into any medications you are taking during your consultation. Depending on the medication these may need to be halted leading up to the surgery.

How long does the procedure take?

Typically this procedure takes one to two hours.
