Le Fort III and Frontal Monobloc Osteotomies

In 1942, Gillies performed a Le Fort III reosteotomy for the first time on a patient with a Le Fort III fracture that had healed in malposition. Similar to the maxillary osteotomies, years passed before Tessier took up this technique in 1967 and separated the entire midface (high-level midface osteotomy) from the skull base and displaced it anteriorly or inferiorly, changing not only occlusal discrepancies but also the position of the bulbi and the nasal skeleton. This also resulted in a significant widening of the posterior airway.
