Loose soft tissue around chin after genioplasty reduction (Photo)

A CT would be helpful to determine if there is any residual bony defects, In the right side profile photo, it appears that your mentolabial fold is deep and this makes the chin appear short. Some defects can be improved with a bone graft or fat grafting. An in person consultation is needed to give further recommendations.

I'm sorry to hear that you are not satisfied with the results of your genioplasty reduction as part of your FFS surgery. It sounds like you may have excess soft tissue in your chin area that is causing indents and an uneven appearance.

It is difficult to make a specific recommendation without a physical examination, but there are a few options that you may want to consider:

Revision surgery: Depending on the severity of the issue, a revision surgery may be able to improve the appearance of your chin. This could involve removing excess soft tissue or using a different technique to reshape the bone.
Fillers: As you mentioned, adding a filler such as fat or hyaluronic acid to the indented areas of your chin may help to create a smoother, more even appearance. This is a non-surgical option that may be worth exploring.
Chin implant: If the bone reduction during your genioplasty has left your chin looking too small, a chin implant may be a viable option. This would involve placing an implant in the chin area to improve its projection and balance with the rest of your face.
It is important to seek the opinion of a qualified and experienced plastic surgeon who specializes in facial surgery, and who has experience with revision surgeries and chin procedures. They will be able to evaluate your individual case and recommend the best course of action to achieve your desired results.

I hope this helps,
best of luck !
