How Much More Chin Projection Can Be Achieved With A Custom Jawline Implant?

Q: Dr. Eppley,  I have some questions about the custom jawline wrap. 

1) I see that you’ve noted the typical maximum horizontal lengthening is around 10-12mm for an implant, if I have an indwelling chin implant, can it be assumed the 10-12mm can be added onto whatever implant I have now? 

2) Adding on to the 1st question, can a custom jawline wrap add in the range of 14-16mm in horizontal lengthening with the presence of an indwelling implant? 

3) If it is possible, does such a big horizontal lengthening effect how much gonial width can be added, because the skin will already be stretched too much? 


A: In answer to your custom jawline implant questions:

1 and 2) While you may get up to 50% more chin projection by a secondary implant augmentation it will not be a 100% increase as the soft tissues can not tolerate that implant load. If you need that much chin projection increase it should be converted to a sliding genioplasty.

3) Whatever is done at the chin does not impact what can be done at the jaw angles in terms of soft tissue stretch.
