Which has more long term complications: SG or chin implant?

Question

Does sliding genioplasty not work well for ONLY forward projections of chin? is there a lesser chanc of displacement with sliding genioplasty than a chin implant. Would there be a risk of displacement even say 10 yrs down the line after a chin implant? What long term maintenance or follow up does chin implant or sliding genioplasty need?

I am doing osseous genioplasties 2 decades ago, my answers:Does sliding genioplasty not work well for ONLY forward projections of chin? >>> to the contrary, sliding genioplasty is the BEST treatment to add forward projection, however it is very limited for other dimensional modifications (height, width, augmentation, reduction)is there a lesser chanc of displacement with sliding genioplasty than a chin implant. >>> sure, there is ZERO chance of displacement with osseous genioplasties (if well done) Would there be a risk of displacement even say 10 yrs down the line after a chin implant? >>> for sure, actually the displacement is likely to happen in the first months, furthermore... it is an oddity a chin implant stays in place without removal 10 years, whilst osseous genioplasties are for a lifetimeWhat long term maintenance or follow up does chin implant or sliding genioplasty need? >>> no one of them need maintenance, however chin implants are limited in lifetime, non versatile, prone to infections, unnatural results, dislocations, etc

Hi, this is a very good question.  Sliding genioplasty is far more invasive than placing a silastic chin implant through a small, curved incision under  the chin.  The tissue dissection, bone cuts and re-approximation of the cut bone segment with metal plates and screws, in a sliding genioplasty, is a much more invasive procedure which for that very reason makes it more prone to possible complications and unwanted side effects.    I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  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.  Hope this helps.
