The mandibular basal or osteotomy or Chin Wing osteotomy, is an innovative technique initially described by Albino Triaca in 2009, and later popularized by Cesar Guerrero, for the management of patients with facial abnormalities that require correction of mandibular basal flange at different levels. It can be used singly or simultaneously with other techniques. This osteotomy has precises indications and requires an experienced surgeon. Its versatility allows changes at mandibular transverse, sagittal dimensions. Reducing the risk of injury to the inferior alveolar nerve, and less noticeable step bone that created with a traditional mentoplasty. Its main advantage is to produce great changes without altering or modifying facial occlusion, allowing use in dentally compensated cases of patients or in which movements are contraindicated orthodontic decompensation. We report the application of the technique and follow up in 8 patients at the University Hospital of the Samaritan, Bogota, Colombia.
