    Total midface deficiency, to include the orbits, nose, zygomas, and maxilla, can occur in both syndromic and non-syndromic individuals. The treatment with combination of Le Fort III and I osteotomy could be used and it is few reported in the literature. The aim of the study is to present how technology can make the procedure for the correction of hypoplasia of the middle third more predictable and safer. The 2 clinical cases were managed under submental intubation and using VSP that generated 3D printing of oclusal splints and cutting guides. Modified oblique Le Fort III osteotomy (MOLFIIIO) and Le Fort I osteotomy were used due to patients present large sagittal discrepancy between maxilla and mandible (18 and 17 mm). The patients presented good outcomes without complications. In this study, the authors demonstrate that non-syndromic patient could be managed safety with MOLFIII and Le Fort I osteotomies for the correction of midfacial deformities using virtual surgical planning (VSP) associated with 3D printing technique and piezoelectric surgery.
