Reduction genioplasty: surgical techniques and soft-tissue changes.

A retrospective study was made of the osseous and soft-tissue changes and clinical results after reduction genioplasty for correction of anteroposterior macrogenia in seven adults. The surgery was performed by a modified technique which maximized the soft-tissue attachment to the inferior and anteroinferior portions of the repositioned segment. The 0.58 ratio of soft-tissue to osseous change was greater than results reported in previous studies. The present article describes the anteroposterior reduction genioplasty technique and the clinical results achieved with its use.
