Genioplasty is a complementary procedure to the treatment of facial deformities with great versatility and esthetic outcome. It is commonly performed in patients undergoing maxillary osteotomies to improve esthetic results. Currently, the most frequently used technique is the horizontal osteotomy of the symphysis. Restoration of the symmetrical facial contour is challenging, particularly in moderate to severe deformities, because of the necessary overcorrection of the bony deformity relative to the normal side. The original genioplasty introduced by Obwegeser, was modified by Sandner and the term “wing” was coined by Triaca. Wing genioplasty was introduced for the correction of deficiency, excess or asymmetry of mandibular bone. This study evaluates the functional and cosmetic results of mandibular inferior border osteotomy. The patient was treated 3-D and the evaluation included clinical, radiographs and photographs analysis, pre- and postoperative. The patients showed excellent functional and cosmetic results, with mandibular plane modification and was treated for advancement with important lateral angle projection. The wing osteotomy is an innovative technique highly predictable for the correction of deficiencies, excess and asymmetries of the inferior mandibular border, reducing the morbidity and many other complications of the traditional bone grafts and alloplastic techniques.
