Lower face remodeling by mandibular angle ostectomy

Abstract

The results of lower face remodeling using various mandibular angle reduction techniques in 212 patients with hypertrophy of mandibular angle are presented. Hypertrophy of the mandibular angle is the most common lower face deformity in Asian women. The deformity can usually be corrected with various types of mandibular angle reduction. The surgical techniques reported include intraoral mandibular angle ostectomy, intraoral ostectomy of the lateral cortex around the mandibular angle, reduction mandibuloplasty by retroauricular approach as well as intra/extraoral approach. The key point for a successful operation is selection of surgical methods and choosing a line for mandible ostectomy based on the different types of prominent mandibular angle. The intra/extraoral approach was the most commonly performed ostectomy in this study and had few complications.
