Surgical correction of the bony contour of the chin.
[G. geneion, chin, cheek, + plastos, formed]

genioplasty

(jē′nē-ō-plăs′tē, jə-nī′ə-)
Surgery of chin, in particular of the mandibular bone, referring especially to chin augmentation, usually motivated by concerns over one’s appearance

men·to·plas·ty

(men'tō-plas-tē)
Surgical repair of the chin, whereby its shape or size is altered.
Synonym(s): genioplasty.
[L. mentum, chin, + G. plastos, formed]

Genioplasty

An operation performed to reshape the chin. Genioplasties are often done to treat OSA because the procedure changes the structure of the patient's upper airway.

(jē'nē-ō-plas-tē)
Surgical procedure performed extraorally or intraorally to reshape the bony contour of chin.

The MF has recently been subject of many studies due to its importance in gaining anesthesia in the region of anterior mandible and also to gain surgical access in endodontic surgery, dental implant placement, genioplasty, orthognathic surgery, fracture management and forensics 1,6,11,12.

In the recent past there is a shift of paradigm from Angles to soft tissue profile as soft tissues largely determines the limitations of orthodontic treatment, from the perspectives of esthetics, function, anchorage planning, retention, relapse and stability.1,2 Growth modification and surgical orthodontics are also aimed at improving the esthetics.3,4 Surgical camouflage including rhinoplasty, genioplasty, cheiloplasty and maloplasty as adjunctive orthodontic procedure has become popular in the recent past again with the aim to improve the profiles.5,6 Orthodontist thus must plan treatment within the patient's limits of soft tissue adaptation and soft tissue contours.

Originally, that paper was not intended to present the method but to demonstrate bone augmentation with a thin cortical bone at the gap created on the genial segment when performing advancement genioplasty. Thin cortical bone was harvested from the sharp lateral upper edge of the advanced genial segment and transferred to the midpoint just leaning on the anterior aspect of the tooth-bearing segment.
Despite the several techniques reported in the literature (e.g., surgical reduction of the tongue base, tongue base stabilization, genioglossus advancement, mortised genioplasty, tongue radiofrequency treatment, hyoepiglottoplasty, and hyoid suspension), many of them should be critically analyzed anyway because they are extremely invasive.
