The search was divided in Main search (PubMed, EMBASE and Cochrane Library), Gray literature (Scholar Google) and Manual search. Twenty-three studies were included, 14 studies evaluated stability outcome and 9 studies surgical complications outcome. The level of agreement between the authors was considered excellent (k=0.893 – study selection and k=0.853 – study elegibility). Segmental Le Fort I osteotomy provides stable outcomes in the sagittal plane, is less stable dentally than skeletally in the transverse plane, and provides little stability in the posterior segment after downward movement. The most recurrent complications are oral fistula (6 studies) and damage to adjacent teeth (5 studies), but the most prevalent complication is postoperative infection (32.62%). Four studies evaluating stability outcome showed a medium potential risk of bias, whereas all studies addressing surgical complications showed a high potential risk of bias. Segmental Le Fort I osteotomy should not be proscribed from the technical armamentarium in orthognathic surgery. On the contrary, the consulted literature suggests it is a useful tool for the three-dimensional surgical correction of maxillary malposition.", publisher = {Pontifícia Universidade Católica do Rio Grande do Sul}, scholl = {Programa de Pós-Graduação em Odontologia}, note = {Escola de Ciências da Saúde} }
