Chin Augmentation (Mentoplasty)

Mentoplasty is an operation to change the shape of the chin. In augmentation mentoplasty, an implant is used to make a small or recessed chin more prominent.

Chin augmentation may be performed on its own or considered together with rhinoplasty. The position of the chin can influence how the nose appears in profile, so the nose and chin may be assessed together when both are a concern. This does not mean that both operations are needed.

What happens before chin augmentation surgery?

At your first consultation, Dr Michael will ask about your concerns, your general health, any previous surgery and what you would like to change. The chin is examined from different views and considered in relation to the rest of the face.

Photographs of your chin may be taken to help with assessment and discussion. If you are also considering rhinoplasty, your concerns about your nose will be discussed and a nasal examination may be performed.

It is important to understand what surgery may be able to change, as well as its limitations and risks. A second consultation may be arranged so that you have time to consider the proposed operation before deciding whether to proceed.

What does an implant mentoplasty operation involve?

Mentoplasty is performed under general anaesthesia. The implant may be inserted through a cut inside the lower lip or through a cut underneath the chin.

A pocket is made over the chin bone and the implant is positioned and secured with metal screws or stitches. Stitches inside the mouth are usually absorbable. When mentoplasty is performed on its own, patients can usually go home on the day of surgery.

What happens after chin implant surgery?

Some swelling, discomfort and tightness around the chin and lower lip can be expected. Opening the mouth and chewing may be uncomfortable at first, so a soft diet may be easier during the early recovery period. Follow the instructions you are given for mouth care, medication and sleeping position.

A follow-up appointment is usually arranged about a week after surgery. You will be given individual advice about returning to work and exercise. Strenuous exercise and pressure on the chin are generally avoided during the early recovery period.

Follow-up appointments are arranged to monitor healing and the position of the implant. The timing and duration of follow-up depend on your recovery.

Are there risks to chin implant surgery?

Possible risks include bleeding or a haematoma, infection, altered sensation or numbness of the chin or lower lip, and changes to lower-lip movement. The implant may move, become noticeable or produce asymmetry. Infection or implant problems may require further surgery, including implant removal. General anaesthesia also has risks, which are discussed with you before surgery.

The likelihood and significance of these risks vary between patients. The planned operation, alternatives and individual risks are discussed before you decide whether to proceed. Published reviews of chin implants report complications including infection, implant movement, altered sensation and the need for revision or removal; the available studies vary in quality and reporting. 

Dr Michael follows patients after surgery to monitor healing and the implant position. The final appearance cannot be guaranteed, and healing and results vary between individuals.

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