Abstract

Broad soft-tissue pedicle genioplasties were performed in 6 patients by horizontal osteotomy of the inferior border of the mandible, with preservation of a musculoperiosteal pedicle to the genial segment. Preoperative, immediate postoperative, and long-term follow-up lateral cephalometric radiographs were retrospectively analyzed to evaluate the osseous and soft-tissue changes of the chin. After a mean follow-up period of 29 months, all cases preserved the initial advancement. No case showed bone resorption from pogonion to the menton region.
The chins advanced by broad soft-tissue pedicle genioplasty had good stability.
