genioplasty
Pronunciation: JEE-nee-oh-plas-tee
Surgical procedure to reshape or reposition the chin through bone modification techniques.
Full Definition
A craniofacial surgical procedure designed to alter the shape, size, or position of the chin through various techniques including sliding genioplasty, reduction genioplasty, or augmentation genioplasty. The procedure involves osteotomy of the mandibular symphysis to advance, retrude, lengthen, shorten, or widen the chin prominence. Genioplasty is often performed in conjunction with orthognathic surgery to achieve optimal facial balance and may be indicated for functional or aesthetic reasons.
Usage
Usage note: Often used interchangeably with mentoplasty, though genioplasty specifically refers to bone procedures while mentoplasty can include soft tissue techniques.
