Most likely the chin implant removal would be a simple operation with minimal sequelae. Your chin should return to its prior condition within a few months.
This is a common question and the answer is that you probably won't have a any droopy skin and your shin will be smaller than with the implant, but possibly slightly larger than before the implant. Usually you go back pretty close to normal.

Hopefully you will have good skin retraction with a small implant for a short period of time. The removal is much less traumatic than the insertion for most implant materials. Good luck. Donald R. Nunn MD Atlanta Plastic Surgeon.
What results should I expect after removing a chin implant
You have had the implant for such a short time I don't think you will see any difference from your preop appearance. The same goes for lip movement...I have no experience with seeing altered lip movement with chin implants.
Status after impalnt removal
This is a tough question to give a meaningful answer because there are many variables. I will try. I would not expect there to be any meaningful residual projection form scar tissue after removal. With regard to mouth movement after removal, it is hard to say. If the procedure was done transoral instead of submental, you might expect a longer recovery.
