Abstract

The maxillo-malar osteotomy is one of the osteotomies developed over the years to correct the deformities of the midface without modifying the nasal projection. After having for many years approached the osteotomy through the classic double access, intraoral and subciliary, we verified the feasibility of this osteotomy via an intraoral route only. For this purpose we modified slightly the classic osteotomy lines, however still including in the mobilized fragment the most prominent and therefore the most aesthetically important portion of the zygoma. At the lower orbital rim the medial osteotomy cut is performed with a fissure bur, the lateral one with an oscillating saw. Both the osteotomies are extended posteriorly in the orbital floor with a fine osteotome. Then, after having performed all other osteotomy cuts, the maxillo-malar complex is down-fractured. The residual thin bone structures which connect the maxillo-malar complex to the cranio-facial skeleton are broken during a careful downfracture, avoiding fracture between the maxilla and zygoma. The complex is advanced and stabilized with intermaxillary fixation, osteosynthesis and bone grafts. A bone graft to the orbital floor is unnecessary
