Chin implant sitting low? I had a medium chin implant put in five weeks ago and most of the swelling should be gone now (photo)

A fair amount of swelling is typical after your procedure and could be causing this. I recommend following up with your surgeon about your concerns.  Swelling will gradually resolve over the next several months. I hope this helps!

While you did not provide before surgery pictures, it certainly appears that your chin implant may be sitting too low as you have little horizontal augmentation and a long chin. You did not state whether it was put in from inside the mouth or from an incision below the chin. But it appears that a revision chin implant procedure is needed.

It certainly appears from your photos that is sitting very inferiorly. The implant can be reposition but not as easy as the first procedure. Because the implant pocket has been stretched out inferiorly you will probably need a couple of screws place to keep the implant in position.

At 5 weeks I would expect it to look better.  It may be the implant has shifted and needs to be repositioned.  Sometimes it is necessary to remove altogether and replace several months down the road.  A sliding genioplasty is always a possibility but a bigger procedure.  It would help to know the type and size of the chin implant as well as the approach used.

An examination of the chin is required to make a determination about whether the right size implant was placed, and whether that implant was placed in the proper position. The chin implant can be removed and replaced in the proper position, if needed under local anesthesia.

From your pictures, it does appear your chin implant is sitting low and not providing you with the desired anterior projection, but it is difficult to fully evaluate without seeing your before pictures with your natural anatomy and chin orientation.  It would be best to followup with your surgeon to discuss your concerns.  Most chin implants can be revised and re positioned if needed. 

You are correct about the swelling. There might be two different problems going on here. First one is that chin implant is sitting too low. Second one which is more serious is muscle Ptosis which is not easy to fix. By removing the chin implant and having sliding genioplasty done, it will help with projection and improve muscle position.
