Chin Implant but my Face is Crooked... It Looks Worse! Help Please! (photo)

I'm sorry you have had to deal with this for the last couple of years.  It is fairly obvious that the implant has migrated down onto the undersurface of your jawbone.  Probably the best and safest course to take would be to remove the implant, allow everything to heal and then come back in 3 months or more and put a new one in.  When placing an implant there are several very important principles to remember to make sure it will be placed correctly and not migrate over time.  First, place the implant in a sub-periosteal pocket.  The periosteum is a connective tissue layer that covers the bone and the implant should go between the periosteum and the bone.  Second, the pocket you create should precisely fit the implant, not too big and not too small.  Third, when I place an implant we always use a type of anesthesia that does not require the patient to be intubated.  If there is a tube going in the mouth then the mouth is open and it makes it more difficult to see exactly where the implant is sitting.  3D imaging helps plan the size and location of the implant.  I hope this information helps.  Chin implants can nicely enhance the results of a rhinoplasty but the technique used to place it is important. 

The chin implant has become mal positioned. Either have it re aligned or removed ASAP! What does your surgeon say??? 

I'm not sure what type and style/size of implant you had placed into your chin, but the simplest treatment would be to remove the implant you have and replace it with one that would be more suited to your face.  There are many styles and sizes of implants and there should be one that would give you good results.
