Abstract

This is to evaluate the postoperative cephalometric changes of the chin advanced by the genioplasty. Thirty-eight patients who underwent advancement genioplasties at Ewha Womans University Mokdong Hospital between January of 2001 and February of 2003. They were followed up for at least 12 months with lateral cephalographs. The remodelling changes of the horizontal linear measurement between the Pogonion and Perpendicular line to FH plane were measured and analysed by Independent sample tests. The chin advancement resulted in $1.3{\pm}0.3mm$ resorption (28.2% of advancement) after 6 months, but in $1.4{\pm}0.2mm$ after 1 year. If the chin was advanced less than 3 mm, remodelling followed by $1.2{\pm}0.2mm$ reduction, but $1.3{\pm}0.3mm$ reduction followed after chin advanced over 4 mm. There were no significant differences in the amount of bone resorption by the gender, number of genial cut-steps and acompanied osteotomies.
