Contouring of the Lower Face by a Novel Method of Narrowing and Lengthening Genioplasty

Abstract

Therapeutic, IV.

A new design of CAD/CAM surgical template system for two-piece narrowing genioplasty

“…A two-piece narrowing genioplasty, sometimes combined with chin lengthening or reduction 2,4 , is a commonly used procedure to recontour the lower third of the face 10 . It is more difficult to develop a surgical plan for a two-piece narrowing genioplasty than a monoblock genioplasty due to fact that the shape and the position of each chin segment will directly affect the surgical outcome.…”

“…Osseous genioplasty procedures are used widely to correct chin deformities 1–4 . These procedures are challenging because the chin deformity may exist in all three dimensions; thus it is critical not only to make a correct diagnosis and surgical plan for the genioplasty, but also to transfer the plan precisely to the patient at the time of surgery.…”

A Simple and Reliable Method of Narrowing Genioplasty Using Biodegradable Screws

“…For patients with disproportionate facial ratios, either a vertical chin elongation or reduction can be carried out during this procedure. 2 Furthermore, anterior advancement or posterior setback of the chin segment could be planned for correcting facial profiles, if required. Osteotomies were performed using a reciprocating saw.…”

“…Among various surgical methods that are used to improve lower face aesthetics, chin narrowing by the Tosteotomy technique has become one of the most widely performed surgical procedures, mainly because of its versatility. [1][2][3] During this narrowing genioplasty procedure, the use of hardware such as titanium plates, screws, or wires is necessary for fixation of the repositioned genial bone segments. As growing number of patients prefer to surreptitiously undergo aesthetic surgery, biodegradable fixation systems offer a valuable surgical option.…”

20 Mandible Reduction

“…modifying the shape of the chin, in conjunction with mandible reduction, is essential to achieve a slimmer and ovalshaped contour. 12,13,14 The authors' current techniques for a prominent mandible are (1) controlling the slope of the mandibular plane by resecting the mandibular angle and controlling the inferior border of the body via a long curved resection technique, (2) reducing the width of the lower face via burring or ostectomy of the lateral cortex, and (3) narrowing genioplasty according to the patient's specific demands. Since the authors introduced the technique in 2008, simultaneous performance of narrowing genioplasty and mandible reduction has been widely called "V-line surgery" since the shape of the contoured jaw line looks like the letter V (Fig.…”
