title: Evaluation of the nasal shape after orthognathic surgery.
abstract: BACKGROUND
  Patients with dentofacial deformities may benefit from orthognathic surgery in the maxilla. Maxillary osteotomy may include procedures in the bone, cartilaginous, and soft tissues of the nose, leading to shape alterations.
  
  
  OBJECTIVE
  To evaluate the anatomic alterations of the nasal region in patients undergoing a Le Fort I osteotomy for advancement or superior impaction.
  
  
  METHODS
  This is a clinical prospective study. Twenty-one patients were evaluated during the pre- and postoperative periods. The positioning of the nasal tip and the modification of the nasal base were evaluated.
  
  
  RESULTS
  The results showed that the nasal tip was superiorly positioned in 85% of the cases, advanced in 80%, rotated in 80%, and there was a wide nasal base in 95%, resulting in esthetic improvement.
  
  
  CONCLUSIONS
  Surgeries of maxillary advancement and superior reposition tend to cause elevation and advancement of the nasal tip, as well as enlargement of the nasal base.
