The Osseous Genioplasty
Genioplasty is the most frequently performed facial bone surgery which is done as an isolated manner or as a combination with other surgeries such as orthognathic surgery or bone contouring surgery.
The versatility of the procedure allows the chin to be adjusted either forward or backward in the anteroposterior dimension, vertically shortened or lengthened in accordance with the frontal proportionate analysis, and to be narrowed to achieve a more slender facial contour.
Although a simple procedure it may be, the genioplasty is error prone and frequently leaves complications and unsatisfactory results.
Surgeon should focus on several key technical points such as positioning the chin segment in an ideal position, avoiding nerve injury, predicting soft tissue changes, and achieving a smooth jaw contour.
The chin deformity is frequently accompanied with conditions such as class II profile, long-face syndrome, asymmetry, and other facial dysmorphologies, so such conditions should be preoperatively evaluated.
