genioplasty
Pronunciation: JEE-nee-oh-plas-tee
Surgical reshaping or repositioning of the chin for functional or aesthetic purposes.
Full Definition
Genioplasty is a surgical procedure that involves modifying the chin through osteotomy, augmentation, or reduction techniques. The procedure can address functional issues such as sleep apnea or aesthetic concerns related to chin projection and facial harmony. Common techniques include sliding genioplasty, where a horizontal osteotomy is made and the chin segment is advanced or set back, and chin implant placement. The procedure requires careful consideration of dental occlusion, facial proportions, and potential complications such as mental nerve injury.
Usage
Usage note: Distinguish from rhinoplasty (nose surgery) and other facial plastic procedures in documentation.
