Objective : The purpose of this longitudinal retrospective study was to evaluate transverse maxillary expansion after a Schuchardt or segmental posterior subapical maxillary osteotomy (SPSMO) in patients with cleft lip and palate (CLP).

Objective : The purpose of this longitudinal retrospective study was to evaluate transverse maxillary expansion after a Schuchardt or segmental posterior subapical maxillary osteotomy (SPSMO) in patients with cleft lip and palate (CLP). 1987-01-01 · The posterior-maxillary osteotomy introduced by Schuchardt was designed to close skeletal anterior open bite. Also, it can be used to reduce a posterior cross bite. 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. 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.

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.

24.2). Bilateral sagittal split osteotomi vid ramus beskrevs första gången av Schuchardt 1942. Obwegeser och Trauner beskrev 1957 en förfinad metod som sedan har blivit den bilaterala sagittal split osteotomi (BSSO) som fortfarande används. 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.
