Chin augmentation is commonly practiced, whether in microgenia treatment, in cases of orthognathic or cosmetic surgery. Located at the crossroads of many specialties, the technique choice still differs according to the surgeon specialiy. A large number of publications on the subject are available. A comparaison between different surgical methods is therefore possible concerning their indications and their complication. The purpose of this study was to carry out a literature review, with updating knowledge, as well as a synthesis indication regarding aesthetic osseous and alloplastic genioplasty. Despite the generalization of "modern" implants in France, prosthetic genioplasty remains more frequently the source of serious complications (infections, extrusions, bone erosions). Similarly, this technique has much more limited indications than osseous genioplasty, which has the advantage of a better longevity. In order to increase the aesthetic appearance of the chin, osseous genioplasty should be performed more easily and more frequently by surgeons on all sides.
