Abstract: The chin plays an important role in the facial balance and harmony. Deformities of the chin are commonly present in cosmetic surgery. Genioplasty is one of the earliest craniofacial contour plastic surgery carried out. There are various techniques for chin deformities including chin augmentation with autogenous grafting or alloplastic materials and genioplasty. Computer assisted surgery, robotics surgery and 3D printing will be widely developed in genioplasty. In this paper, the development and present situation of genioplasty were reviewed.

Key words: Chin deformity, Genioplasty, Computer assisted surgery
