Would a sliding genioplasty help correct my receding / weak chin? (photos)

You will benefit from both horizontal and vertical movement. Bringing your chin forward and down will create more facial balance and a stronger profile. It will add length and definition to your jawline and should improve your labiomental fold as well. Some of the great benefits of a genioplasty is that it will last forever, and all the incisions are made from the inside, which means no external scarring.

A sliding genioplasty is performed by an oral surgeon under general anesthesia in a hospital setting with an overnight stay. It is much more invasive, and it's usually done with the teeth are significantly out of alignment. If you are purely looking for a cosmetic improvement, then consider placement of a small chin implant under local anesthesia as an outpatient procedure done in the office setting.

Hello! Great questions and thanks for the photos. A sliding genioplasty will give you a permanent result unlike using fillers. A chin implant is another option but does pose risks long-term. In your case, advancement forward would be beneficial. You could add some vertical height as well. Movement will help to stretch the skin, though I advise my patients that that may be a secondary benefit and not the primary aim of surgery. It does not tend to make the labiomental fold look unusual. Hope this is useful!

Making an assessment regarding augmenting the mandible can be a little tricky, and sometimes more complex than people think.
The mandible can be lacking in size and projection in different parts of the bone. The chin is only one part of the mandible and many people who have it and insufficient or facial skeletology imbalance with a small mandible will have deficiencies in various parts of the mandible.The overall size of the mandible is generally determined by how the dental occlusion comes together. This represents the relationship between the mandible and the maxilla.Most individuals who have an under sized mandible, will have a significant overbite occlusion. The relationship with the upper and lower teeth has little to do with the chin, because the chin sits in front of the incisors.
To assess the chin, follow the contour of your lower lip. Be careful attention when it comes to the little fold or crease at the bottom of the lower lip called the labiomental angle. If someone has a deep labiomental crease or sharp labiomental angle then anterior or forward, augmentation of the chin needs to be done carefully. It’s important to differentiate if the lack of projection is in the tip of the mandible, or the chin itself or further back in the body of the mandible.
I suggest having multiple in person, consultations with local, oral surgeons and plastic surgeons. Some plastic surgeons are comfortable doing a sliding genioplasty while others will prefer using implants.
Each of the procedures can accomplish similar outcomes and both procedures has certain inherit advantages, and disadvantages.

you have a high angle growth pattern with a 'narrow' lower jaw. The caution is that advancing the chin only without considering the area of the rest of the jawline will make the face look more 'narrow and longer'. The genioplasty is the way to go but only if you consider some augmentation 'behind' the chin for best results.
