Cheek and chin implants to make face longer and wider?

 A chin implant is recommended when patient's have a weak and recessive chin profile, to augment the chin forward and give a little bit of width. Cheek implants are recommended for patients who have a flat cheek profile to augment the cheeks. Both implants are composed of Silastic in the size of the implant is determined at time of the consultation. For many examples of both procedures, please see the video and the link below

Being an option, chin implants (and fillers) have serious disadvantages, specially in
the mid and long term, patients are rarely happy with them after 5-6
years, all are out by then or later.Consider the chin advancement by means of sliding genioplasty, the advantages are:-lifetime procedure, no more revision or renewal procedures-more natural than implants-no visibility of implant edges during gestures-improves
the double chin effect at the sub-mental muscles (floor of mouth)
hammock caused by lack of tension there; also improves the shape and
tension of perioral muscles; implants do no offer this feature-horse-shoe enhancement, covering the chin and also the jaw sides of it-no future displacements or neuritis of mental nerves-practically zero infections and 100% healing of bones-no
need for complex plates and screws that may need future removal; just
steel wires synthesis may suffice, they stay buried into bone callusThe cons are:-expensive, but cheap if you consider the lifetime pros-technically
demanding, few surgeons are experienced or comfortable (though I
personally perform 100% of the chin augmentations by this osseous
method, always after offering the patients both options)-scary for the patient (though not so much if you explain well the stuff around it)You'll
find in this website dozens of negative experiences with chin implants
in the short and mid term, do read my profile's Q&A and you'll find
them too. I am doing sliding genioplaties for 15 years with the highest
success and no one patient regreted, totall the opposite, I did many
chin implant removals and one staged sliding genioplasties to replace
them.

With proper cheek and chin implant selection the face can definitely be made to look wider. But when it comes to making the face longer, a custom jawline implant would have to be designed and used as no standard implant can achieve that effect along the entire jawline.
