Relationship between dimensional tissue changes in genioplasty: integrative review

JAMILLE DE FREITAS BAROLO e RENATA PITTELLA CANÇADO

Introduction: Genioplasty is a surgical procedure that allows three-dimensional changes in position and con- tour of the chin, resulting in significant improvements in facial esthetics. Objective: Determine the relationship between soft tissues and bone movements in the genio- plasty procedure, by means of a integrative literature review, using the following points: pogonium (Pg), soft tissue pogonium (Pg’), menton (Me), soft tissue menton (Me’), mentolabial sulcus (Si), and Point B. Methods: An integrative literature review was carried out using three databases, with the descriptors “Mentoplasty and soft tissue” and “Genioplasty and soft tissue”. Results: From the established criteria, articles were selected to compose the sample, among them: a systematic review, prospective and retrospective studies. In the forward and backward movements, the averages obtained were respectively 0.91:1 and 0.65:1 in Pg’:Pg horizontally; 1.05:1 and 0,9:1 in Si:Point B horizontally; 0.82:1 and 0.88:1 in Me’:Me vertically. Vertical reduction showed the ratio of 0.88:1 in Pg’:Pg horizontally; 0.79:1 in Pg’:Pg vertically, 0.89:1 in Si:Point B horizontally and a mean of 0.4:1 in Me’:Me vertically. Conclusion: It can be observed that apparently, in movements of ad- vancement and inferior replacement, a closer relation between soft and hard tissue was obtain, the same not being true in backward and vertical reductions.
