Major contributions to the development of the LF I osteotomy came from Axhausen in 1934, who performed the first total osteotomy of the maxilla with immediate repo-sitioning.1 Later, Schuchardt pioneered in separating the maxilla from the pterygoid bone in 1942 to increase the advancement and ease of movement of the maxilla.23

Three of these surgical innovations are presented with illustrative case histories.

The Schuchardt operation could be performed intraorally and led to a Several months later, after returning to Hamburg, Schuchardt performed the procedure on a patient himself, named the procedure “schräge Osteotomie” (oblique osteotomy), and published it locally in 1954. Early on, a modification was experimentally developed by Giorgio Dal Pont but was never used clinically.

Posterolateral segmentary maxillary impaction osteotomy has a role to play in the treatment of gaps between the upper and lower jaws. It has several advantages, especially an uncomplicated postoperative period and the single-maxillary contention it provides. The indication must be established after an articulator assessment in order to take into

But in this latter case, the most important problem is the difficulty in expanding the maxilla because of the relative inelasticity of the palatal mucosa. Schuchardt 7 modified the horizontal flat osteotomy by introducing a technique in which a cortical osteotomy was performed in an oblique way starting from just above the lingula and reaching the buccal cortex 1 cm more caudally without touching the intra-alveolar nerve (IAN). The Schuchardt operation could be performed intraorally and led to a Several months later, after returning to Hamburg, Schuchardt performed the procedure on a patient himself, named the procedure “schräge Osteotomie” (oblique osteotomy), and published it locally in 1954.

This technique was carried out via an intra-oral approach and introduced the popularization of the BSSO. Trauner and Obwegeser6 subsequently further developed and popularized this technique In 1942 Schuchardt first advocated the pterygomaxillary dysjunction. In 1949 Moore and Ward -- horizontal transaction of the pterygoid plates for advancement In 1965 Obwegeser -- complete mobilization of the maxilla so that repositioning could be accomplished without tension. Bone grafting to enhance stabilization for LeFort and anterior osteotomies -- by Cupar, Gilles and Rowe and Obwegeser. Early description of the rigid fixation of maxillary osteotomies were published by Michelet and The purpose of this work was to describe a clinical case with reduced vertical height in both the posterior sectors, due to maxillary dento-alveolar extrusion in mandibular edentulous space, as a result of some extractions which have not been promptly replaced by a prosthetic rehabilitation, eventually resolved with a bilateral posterior segmental maxillary osteotomy (PMSO).

Patients and Methods: Seventy-three consecutive patients, scheduled for elective bimaxillary osteotomy, were included in this double blind, randomized, controlled trial. They received either a bolus of tranexamic acid (20 mg/kg) or placebo (normal saline) intravenously just before Schuchardt described a posterior segmental osteotomy based on similar principles.

The Schuchardt posterior maxillary osteotomy has also been used though with mixed reports of its stability. Delaire reported a technique consisting of a sagittal split osteotomy of the body of the mandible which was reported by Joos et al. as giving excellent stability. Upper jaw osteotomy according to Schuchardt is a relatively rarely performed surgical procedure due to its narrow range of indications.

Segmental osteotomy of the maxilla or the mandible, or simultaneously of both maxilla and mandible, according to Köle (1974) is advisable when the bases of both maxilla and mandible have a normal cephalometric location in the skull. Segmental osteotomies should be employed to treat mere variations in the region of the alveolar process.
