Captain America shield genioplasty

The chin represents one of the most important determi- nants of the facial aesthetics. Like many aesthetic parameters, the ‘‘ideal’’ chin has changed in history regarding projection and prominence. From the Renaissance’ retrusive profiles, stronger and more defined mandibular contour are nowadays desired both by masculine and feminine population. This change in the ideal references plays an important role in diagnosis and treatment planning. Various techniques for chin augmentation have been described, using both alloplastic materials and osteotomies. An interesting osteotomy variant, so-called chin shield osteot- omy, has been described by Triaca et al to avoid a deep mentolabial fold. The authors describe herein the use of a shield plate, very similar in his form to the Captain America’ shield, that can at the same time provide bone fixation and soft tissues sustain in the mentolabial fold region, preventing the invasion of the gap between the bone fragments by the connective tissue, as it happens in a Guided Bone Regeneration procedure.
