Some people consider having a chin implant in order to elongate or slim their face. However, it should be noted that the prosthesis is primarily designed to improve the profile or forward projection thereby correcting the appearance of a recessed chin, according to the California Surgical Institute website.
Nonetheless, customized chin implant can give a few millimeters of added height to the chin and thus may give an illusion of a more elongated face, although the effect is very subtle.
Simply put, chin augmentation for round face provides no or very little improvement.
When the patient’s primary goal is to slim a markedly round face, her surgery should take into account several factors that may include a weak or recessed chin, wide jawline, chubby cheeks, or a combination of them. Some people require more than one procedure to achieve proportionate results and more slimming effects.
Chubby cheeks are often caused by excess fat, which can be removed with a procedure called buccal lipectomy. This involves a small incision created inside the mouth in order to remove a walnut-sized fat and thus improve the facial contour.
Most surgeons prefer calling the procedure buccal fat reduction, instead of removal, because removing the fats entirely can result in a gaunt appearance, which might become apparent right after surgery or years down the road due to age-induced facial volume loss.
Hence, the vast majority of doctors offering buccal fat reduction take the conservative route—i.e., they remove only small amount of fat—to prevent premature aging of the face.
Occasionally, a markedly round face is caused by wide jawlines. In the past, most surgeons would perform a surgery in which the masseter muscle, the one responsible for chewing, was shaved down. But nowadays, Botox injection can serve as a great alternative without the prolonged downtime and other risks associated with surgery.
Botox weakens the masseter muscle and thus causes it to shrink. However, the effects can only last 4-6 months and thus it entails regular touchups.
