Objective:

To describe the changes of the nasal pyramid when performing a Le Fort I osteotomy and its cosmetic management complementary to the orthognathic surgery.

Materials and Methods:

An electronic search was made in PubMed, EBSCO, Scopus, The Cochrane Library and Epistemonikos using the keywords “Le Fort 1”, “orthognathic surgery”, “maxillary surgery”, “nasolabial changes”, “nasal change”, “nasolabial esthetics”, “soft tissue”, “nasal profile”, “nose” and “cosmetic” related to each other with the Boolean terms AND and OR.

Results:

25 articles were selected; 15 observational studies, 5 narrative reviews, 3 clinical trials and 2 technical notes.

Conclusion:

Nasal changes tend to follow a certain pattern that allows to predict them when facing surgery: increase of nose projection, decrease in columellar length and widening of the alar base, among others. As for other aspects such as the nasolabial angle or the final position of the nasal tip, it has not been possible to define a common pattern. To avoid them, several techniques have been described. However, more evidence is needed.
