Schuchardt 20 of Itzehoe, Germany, a pupil of Wassmund at Rudolf Virchow Hospital, who later became a prominent maxillofacial surgeon in Berlin, introduced the intraoral approach for the “step” osteotomy of the vertical ramus in 1942.

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).

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.

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 1984-12-01 · Although Schuchardt was the first surgeon to report segmental maxillary surgery for functional correction, the demonstration that part of the upper jaw could be segmentally downfractured and returned to its original position and that it would then heal without complication was provided as long ago as 1867 by Cheever.4,5 In 1960 Kutner6 described a one-stage modification of the Schuchardt procedure and, in 1968,7 reported his follow-up results.
