Does anyone know of a surgeon in the Miami area (or Florida) who does silicone hip implants?

Extremely few board certified plastic surgeons perform cosmetic hip implants nationwide. Because of this it is crucial to do your research and find a surgeon that has the experience, even if you have to travel a long distance to have it done right the first time.  Like any surgery, the first time around has the absolute best chance for aesthetic and/or functional success and that revisions for botch-jobs almost never achieve as good results. Find a specialist that can show you good before and after photos of actual patients, can explicitly describe the procedure and recovery to you, has plenty of positive reviews and seems overall respected in her/her community, and someone you trust and simply feel comfortable with. 
Unfortunately fat grafting to the hip area is frequently met with poor success because, again, there is no muscle there to place the fat into and thus is does not survive. Another thing is, if you are asked to purposely gain weight (i.e. fat) for the procedure, the fat you lose first as you get back to your baseline weight after surgery is that very same fat that was transferred into your buttock/hip...so don't fall victim to this recommendation.  Glad to be of help. 

I am not aware of any board certified plastic surgeons in that area that specialize in hip implants. specialize in hip implant surgery however Im in NYC. Please be sure to choose a board certified plastic surgeon who specializes in buttock implants and has a proven history of success with such a surgery.

Dear Diane,   Posting your back and side view pictures of your butt would have been helpful.I assume that your goal is to achieve round hips and fill in the all too common hips indentation.    I have been doing butt implants surgery over the last 18 years and performed the surgery on over 600 patients. My technique, which is using oval round ultra soft silicone implants placed in the subfascial plane, gives you both nice projection and round hips, which can not be achieved with the intra muscular technique.   So, find an experienced board certified plastic surgeon who performed  the sub fascia technique in accredited surgery center for your safety.Most importantly, check the before and after pictures in the photo gallery, to make sure that they are numerous, consistent and attractive with nice 'S' curve, nice projection, round hips and natural look.               Best of luck,                                    Dr Widder
