CHIN SURGERY

Dr Chia Hui Ling

Chin surgery reshapes a chin that is weak and recessed, overly prominent, or asymmetric, to bring better balance to the lower face and profile. The chin has an outsized effect on how the whole face reads in profile, so even a modest change here can noticeably improve overall facial harmony.


•      Improves facial profile and balance, especially in relation to the nose

•      Can sharpen jawline definition and reduce the appearance of a 'weak chin' look

•      Corrects chin asymmetry

•      Implant augmentation is reversible; bony surgery (genioplasty) offers a more permanent structural change

•      Often paired with rhinoplasty when both nose and chin affect the same profile balance

•      A chin that appears weak, recessed, or disproportionately small for the face

•      An overly prominent or asymmetric chin

•      Good dental and jaw health (a dental assessment is sometimes needed beforehand)

•      Realistic expectations of a proportion change rather than a completely different face

•      Adults whose facial growth and bone development are complete

•      Double chin reduction using liposuction techniques further enhances the contour of the chin and jawline.


Chin changes often make more difference to your side profile than to how you look straight on, which can be worth remembering when picturing the result. Because the chin, jaw, and neck all influence each other visually, a full facial assessment is usually more useful than looking at the chin in isolation.


Double chin reduction using liposuction techniques further enhances the contour of the chin and jawline.


TREATMENT

Three main approaches exist:


A chin implant, usually silicone, is placed through a small incision under the chin or inside the mouth, and is comparatively simple and can be removed or exchanged later.


A sliding genioplasty involves surgically cutting and repositioning the chin bone itself, fixed with a small plate and screws — more versatile for larger or multi-directional changes, but a more involved recovery.


Chin reduction, shaving down bone, suits an overly prominent chin. These are done under local anaesthesia with sedation or general anaesthesia depending on complexity.



•      Implant surgery takes about 45 minutes to an hour; genioplasty typically 1 to 2 hours

•      Swelling and bruising are common for 1 to 2 weeks

•      A soft diet is often recommended for the first few days, especially with an intraoral incision or bony surgery

•      Temporary numbness of the chin or lower lip is common during healing

•      Return to work is typically about 1 to 2 weeks for implants, and 2 to 3 weeks for bony surgery

•      Final contour is usually visible by 6 to 8 weeks, though subtle swelling from bony surgery can take longer


  • Preparing for Surgery

    Your surgeon will advise you to avoid blood-thinning medications, anti-inflammatory drugs or herbal supplementations as they can increase the risk of excessive bleeding during surgery. 

  • Surgery

    Chin Implants:

    A chin implant surgery is carried out as a day surgery procedure, under general anaesthesia or local anaesthesia with intravenous sedation. Implant may be inserted through a cut inside the mouth (lower buccal sulcus) or through a skin cut under the chin. The surgery takes around an hour.  The swelling and bruising may last for 1 – 2 weeks.


    Genioplasty:

    This surgery is usually performed from inside the mouth, along the lower buccal sulcus. The lower segment of the chin bone is cut and pushed forwards to augment the chin. or moved backwards or shaved down to reduce the chin. Plates and / or screws are placed to fix the new bone position. There will be more swelling, compared to a chin implant and lasts around 2 weeks. The final result is seen usually after 3 months.


    Chin Fillers / Fat Graft:

    Injection of dermal fillers and fat graft is an another way to augment the chin. The results are more subtle and suitable for those looking for, or needs, less enhancement. The effects of fillers are temporary and lasts for a few months to a few years, depending on the type of fillers. Fat grafting results are more durable but after each fat grafting session, a portion of the fat injected will resorb and having another session of fat graft is common.


  • Post-Surgery Care

    Bruising and swelling are expected after surgery. Major swelling should subside by 1 to 2 weeks for chin surgery. The final results is often apparent after 3 months. You may be given a compression garment after genioplasty.

COMPLICATIONS AND MANAGEMENT

Risks differ somewhat depending on whether an implant or bone reshaping is used.



•      Swelling and bruising

•      Temporary numbness of the chin or lower lip, occasionally prolonged

•      Asymmetry

•      Implant malposition or shifting over time (implant-specific)

•      Implant extrusion or palpability under thin skin (implant-specific)

•      Infection

•      Nerve injury causing longer-lasting numbness or lip weakness (uncommon)

•      Bone healing issues, such as delayed union, with genioplasty

•      An aesthetic result that does not meet expectations, occasionally requiring revision


FAQs

Implant or bone surgery — which is better?

It depends on how much correction is needed. An implant is simpler and reversible, suited to smaller projection changes, while a sliding genioplasty offers more flexibility for larger or multi-directional adjustments, at the cost of a more involved recovery.

Will my lip feel numb afterward?

Temporary numbness of the chin or lower lip is common because of a nerve that runs close to the surgical area. Most people regain normal sensation over several weeks to a few months.

How long is recovery?

Most people plan for about one to two weeks of social downtime, with several more weeks of residual swelling before the final shape is fully visible.

Is the change permanent?

A genioplasty is a permanent change to your own bone structure. Implants can be removed or exchanged later if your preferences change.

Can it be combined with jawline or neck procedures?

Yes, chin surgery is often combined with neck liposuction or jawline contouring, since these areas work together visually.

Will it affect my teeth or bite?

Genioplasty is planned carefully to avoid the tooth roots and bite, and your dental and orthodontic history is usually discussed as part of planning.
