To comprehensively assess and describe the three-dimensional changes in nasal morphology following Le Fort I osteotomy.

Search of PubMed, Google scholar and institutional library database. In addition, bibliographies of included studies were hand searched to identify potentially eligible studies that were not captured by electronic search.

A total of 574 participants were investigated who underwent Le fort I osteotomy surgery. The participants were assessed on alar base width, nasolabial soft tissue, nasal septum deviation post le fort I orthognathic surgery. Mean age 18 - 30 years of age. 10 out of 11 articles in the review have established a strong correlation between le fort I osteotomy and nasal soft and hard tissue changes.

Le fort I osteotomy has pronounced consequences on nasal morphology. This review provides an inventory of pre-surgical and post-surgical nasal soft and hard tissue alterations in le fort I osteotomy surgery. Surgeons must thus carefully evaluate the patient's nasal anatomy and plan the surgical approach accordingly.
