10 months post op of Chin Implant, is it safe to get chin fillers for extra length and projection?

Adding a filler (my preference is lipograft/fat) is an excellent idea.  First and foremost it can be done in the office with minimal local and you, the patient, can participate in the decision of how much volume and where to put the volume and do it all in the upright position which is paramount to achieving the result you desire.  Furthermore, a lot of times the "perfect" implant(size adn/or shape) does not exist and injects with a filler allows the surgeon to "adjust" the result.  However, I share the concern of my colleague that all the swelling should be gone before the injection.  Also, keep in mind if you choose a temporary filler the fix will be temporary.  I wish you the best.

You should be OK with fillers.  Let the doctor doing the fillers know you have a chin implant.  If a lot is needed I would recommend a larger implant.  Fillers are best for touch ups in my opinion.   Good luck.  Donald R. Nunn MD  Atlanta Plastic Surgeon.
