(mentoplasty) involves the augmentation, reduction, or
general reshaping of the chin. The two most common methods are: chin
augmentation, which reshapes the chin by inserting a silicone implant under
the skin, and chin reductions, which involve bone reduction with power bone
A more serious type of procedure, craniofacial surgery, corrects misshapen
jaws caused by misalignment of the teeth and jaws (malocclusion), or mild
inadequate tissue development (hypoplasia) which can appear as a recessed
upper jaw. Patients with a major chin deficiency require bone surgery (osteotomy)
where the bone of the chin is moved forward following various oblique bone
incisions, thereby reshaping the chin.
In chin augmentation surgery, implants are used to change the underlying
structure, which affects the overall balance of facial features. Often chin
implants are used together with other facial implants, particularly cheek
implants, however, they can be used alone. This operation is often performed
in conjunction with nose surgery
as well as a facelift
and/or liposuction of the face and neck.
Chin implants are made in various shapes and sizes. They are made out of
both solid and semi-solid materials.
