Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over the 30 years. From the photos your chin is quite weak as are the back portions of the jaw line. When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy, the lower face looks short, de-emphasizes the lips and allows early formation of a "double chin". The silastic chin implant adds forward projection to the chin thereby creating harmony and balance to the lower face. Using the same incision, liposuction can be performed to reduce the fat and further shape the neck. Excess skin, from below the chin, can also be removed through the same incision. I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty. I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone. In my opinion, you are a good candidate for chin implant surgery. You can augment both the chin and back portions of the jaw line but I prefer using 1 syringe of a thicker HA filler called Restylane Lyft (previously called Perlane) or Radiesse. In the long run a silastic chin implant will be far more cost effective than repeated filler injections to the chin. In addition, when augmenting the jaw line in women, it's paramount to use precise and accurate placement of the dermal filler to the back portion of the jaw line in a manner that does not "masculinize" the jaw. In my experience and despite its recent increase in popularity, fat transfer (fat injection) offers "far" less of a reliable and predictable volume for facial shaping than an off the shelf dermal filler or facial implant. For that reason, I do not use fat to shape the cheeks, chin, lips or jaw line. Tissue physiology is quite simple. Tissue requires a blood supply in and out as well as lymphatic connections to remain viable and alive. Once fat is removed from the body all of these things have been disrupted. Just because the removed fat is mixed with PRP or something else doesn't make the blood and lymphatics magically re-appear. The fat at that point is not living tissue which means that it's prone to being dissolved by the body (most likely in an uneven and unpredictable manner). Injecting fat back into the face does not create the required elements to make the fat living tissue once again. So the argument that fat is alive and viable in the face once it's been removed and re-injected makes no sense to me as a physician and surgeon. The other issue that I have with fat transfer is the lack of precision. Fat is thick by nature which means it's not the same consistency as an off the shelf dermal filler. Fat injections use an increased volume injected in an attempt to compensate for the volume loss that "will" happen. This means a lack of specific shape and volume that simply can not begin to compare with the specificity of using a silastic facial implant of a "known" shape and volume. In that regard fat offers too much of an unknown to make it a reliable and predictable method for facial shaping. There's a significant difference between a small and medium sized chin implant and using 1 versus 1 1/2 syringes of a dermal filler. So you can imagine the magnitude of difference there is between retaining 60% of 25cc's of fat versus 35%. In my humble opinion, I just don't see how fat could possibly be used to precisely shape facial features? Hope this helps.
