This study examined the immediate and postsurgical changes in the hard and soft tissues of the chin after advancement genioplasty by means of oblique osteotomy of the mandibular symphysis. Twenty-three patients who had undergone this procedure were evaluated cephalometrically for up to 6 months after surgery. The results indicated that the position of the genial segment is stable after advancement. There was a good correlation between the amount of hard versus soft tissue change with surgery in the horizontal direction but a poor correlation in the vertical plane. There was, however, a great amount of variability from one patient to the next in most of the variables examined. Follow-up results were generally very stable.
