Clinicians can effectively use hyaluronic acid, autologous fat calcium hydroxylapatite and poly-l-lactic acid to augment chins. But the best filler choice depends on, among other things, the patient’s anatomy.
The authors cite research on chin augmentation in Asian patients, which found high-viscosity hyaluronic acid or calcium hydroxylapatite fillers were best. Authors of this paper suggest those same filler types effectively improve the anterior, transverse and vertical chin dimensions.
“The properties of fillers inform our use. Those with greater ‘lift’ are typically used deeper, in a more depot-like fashion to increase chin size, while other fillers are more appropriate for superficial injection and blending,” she says.
The paper’s authors use a combination of depot and threading techniques.
And similar to implants in the cheek, chin implants are often combined with fillers to achieve best results.
“Over time, age-related bone resorption may result in an obvious or unnatural appearing chin implant. This effect can be minimized through the use of fillers to blend and soften the chin,” Dr. Wilson says.
Potential complications of filler use in the chin are similar to those that might occur with use elsewhere in the face, according to Dr. Wilson.
“Of particular concern are contour irregularities that may result from superficial injection and vascular compromise.
Often, patients require concomitant therapies to achieve their desired results, she says.
“Perhaps the most common technique is injection of fillers to treat volume loss along the mandible or in the lips, mental crease, marionette [lines] and oral commissures,” Dr. Wilson says. “Most patients with chin retrusion also benefit from neuromodulator injection to the mentalis, as it is often hyperdynamic in this population. Other surgical, injection and device-based therapies to address skin laxity, submental fat accumulation and platysmal bands can also be combined with chin augmentation for superior results.”
