Abstract
OBJECTIVE: To comprehensively assess and describe the three-dimensional changes in nasal morphology following Le Fort I osteotomy. METHOD: 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. RESULTS: 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. CONCLUSIONS: 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.
