Chin Augmentation Sydney

Chin Augmentation surgery or genioplasty is a surgical procedure to reshape the chin either by enhancement or reduction surgery of the bone.

An aesthetically pleasing face requires proportional harmony between the upper, middle and lower thirds of the face. This harmonious balance is no more important than the relationship between the middle third, namely the nose and cheek with the chin. A “ weak” chin may in fact be a result of a prominent nose, which throws out the balance between these two very important cosmetic subunits.

Occasionally I recommend a genioplasty to a patient having a rhinoplasty in order to achieve facial proportion, as the size of the chin may magnify or minimise the perceived size of the nose. Genioplasty helps provide a balance to your facial features so that you feel better about the way you look.


Two broad categories exist for chin enhancement, operative and non-operative. The latter is achieved with temporary fillers and I use this for cases that need only a minor degree of augmentation.
The operative approach is far more predictable and long lasting. This can be achieved with an implant or a surgical procedure, called a sliding genioplasty.

In a sliding genioplasty, the tip of the chin bone is cut and moved into a more proportionate position. It is then secured in place with plates and screws. Should the permanency of a sliding genioplasty be a concern to you, then I would use an implant to augment the projection of your chin.

Both procedures can be performed with an incision on the inside of the mouth or on the outside just below the chin in a well concealed area.

I use advanced 3D computer generated imaging (not photoshop) to try and simulate the predicted post-op result. During your consultation we will go through your 3D image and using my simulation software plan your operation and likely post-operative result. I admit 3D simulation may not be 100% accurate and results may slightly vary from simulated images, but it is the most precise tool we have to predict outcome. Far more reliable than other patients’ before/after photographs or using photoshop.


A genioplasty is performed under general anaesthetic as a day case. Patients usually take 1-2 weeks off work during which time a special pressure garment is worn to support the new shape.

What are the potential risks and complications?

Allergic or hypersensitive reaction to the antiseptic, dressings or medications

  • Immediately following your surgery you may experience short-term nausea and vomiting due to the anaesthesia
  • You may have a sore throat as a result of the breathing tube that will be used during the general anaesthesic
  • Bleeding from the incision site
  • Infection that may require antibiotic treatment or in rare cases, additional surgery

swelling, pain and bruising around the incision site

  • Temporary numbness of the lower lip and chin area
  • Difficulties with smiling for several weeks following the surgery
  • A blood clot may form beneath the site of the incision and drainage may be required
  • Additional surgery may be required if the implant moves or shifts
  • Following the surgery, you may experience short-term nausea and vomiting as a result of the anaesthesia.
  • Smokers or diabetics may experience slow healing
  • You may develop keloid or hypertrophic scars which are raised and thickened scars. This type of scarring may be unsightly, annoying and itchy, however, they are not threatening to your health and rare if you have no family history of the condition. Scars inside the mouth rarely form keloid or hypertrophic scars, but should you need an external scar there is a slight risk of this occurring.


Costs associated with a chin augmentation varies between: $7000-$9000 depending on a number of factors:

  • Anaesthetist’s fee
  • Private hospital or day surgical facility fees
  • Need for post-operative garments
  • Implant costs
  • Surgical assistant’s fee
  • Need for other facial plastic surgical procedures, such as eyelid rejuvenationfaceliftneck lift, brow lift or rhinoplasty.
  • After our consultation my staff will give you an itemised account of the total cost.
