Chin shield osteotomy – a new genioplasty technique avoiding a deep mento-labial fold in order to increase the labial competence

Profile changes after conventional and chin shield genioplasty

“…7,8 Other modifications made from time to time include sagittal split genioplasty, 9 M shaped genioplasty, 10 horizontal flip genioplasty, 11 oblique mandibular chin-body osteotomy for correction of broad chin, 12 and transverse reduction genioplasty to reduce width of chin. 13,14 Triaca et al, 2 introduced chin shield osteotomy as a new genioplasty technique to avoid a deep mentolabial fold and increase labial competence. It has also been reported that genioplasty performed during puberty promotes spontaneous lip closure 15e17 as was also seen in both our groups where lip competency was achieved after genioplasty.…”

“…Chin shield osteotomy technique for genioplasty, is a modified technique that allows vertical lengthening as well as horizontal augmentation of the chin, supports mentolabial fold, limits its depth, and improves labial competence. 2 Hence, this study was planned with an aim to compare the conventional oblique osteotomy for genioplasty without any bone substitute, and chin shield osteotomy with hydroxyapatite collagen (HA/Col) graft soaked in platelet rich plasma (PRP) and study the profile changes.…”

Le Fort I Osteotomy for Maxillary Repositioning and Distraction Techniques

“…Because the patient's main request in dentofacial deformity treatment is a new aesthetical balance of the face (see fig.1) involving good occlusion, good masticatory function, aesthetic of the smile, aesthetic of the facial skeleton contour (zygomatic and mandibular border evidence) and high ratio between facial skeleton and skin amount for good skin tension and juvenile looking; a new kind of operation and surgical planning has been developed in maxillofacial surgery (Merli et al, 2007;Triaca et al, 2004Triaca et al, , 2009Triaca et al, , 2010.…”
