Chin reduction in profileplasty.
An intraoral method of reduction mentoplasty by subapical horizontal osteotomy of the mandibular symphysis is used in the profileplasty of patients with a protuberant chin who have a normal or functionally satisfactory occlusion. Dental and cephalometric evaluation are necessary to determine if resection of the mandible or orthodontic surgery is necessary for correction of the facial deformity. Because of the tendency toward postoperative osteoneogenesis and fibrosis, overcompensation in the amount of bone removed is important in gaining the maximum aesthetic improvement.
