maxillary osteotomy techniques. Three of these surgical innovations are presented with illustrative case histories. (Received fbr publication Octoher, 1978 ).

2007-03-13 · Sagittal split osteotomy (SSO) is a surgical technique largely employed for mandibular mobilizations in orthognatic procedures. However, the traditional design of buccal osteotomy, located at the junction of mandibular ramus and body, may prevent more extensive sliding between the bone segments, particularly on the advance, laterality and verticality of the mandibular body.

Published the famous “intraoral sagittal split of the mandible”. 1958: Dal Pont. Metatarsal shortening osteotomies are often used to correct angular deformities or toe dislocations, most commonly seen in hammertoes or claw toes. A Bilateral Sagittal Split Osteotomy (or BSSO) is a type of jaw surgery where the lower jaw is separated from the face and repositioned. This repositioning is also  The Effects of Le Fort | Osteotomy With Maxillary Movement on. Articulation, Resonance ryngeal walls (Schuchardt, 1954; Converse et al, 1974;.

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. Later, in 1942, Schuchardt5 was the first to describe a sagittal osteotomy of the mandibular ramus. This technique was carried out via an intra-oral approach and introduced the popularization of the BSSO.

Upper jaw osteotomy according to Schuchardt is a relatively rarely performed surgical procedure due to its narrow range of indications. Within the framework of a clinical follow-up examination using this method, we studied the long-term results in 26 patients, employing cephalometric analysis and analyzing the clinical findings.

two-stage procedure for anterior maxillary osteotomy. was advocated by Schuchardt [4] in 1954.

The Schuchardt procedure can be used to shorten posterior maxillary height, but it is rarely used in the USA because it requires either an interdental osteotomy or a tooth extraction (Fig. 24.2). Fig. 24.2

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.

8 Several modifications of the PSMO have been described using either horizontal or vertical buccal incisions, a direct or transantral approach to the palatal osteotomy, and varying degrees of exposure of the palatal bone before osteotomy.1-'6 A pictorial review of several The goals of surgery are to prevent functional disorders and restore facial symmetry, volume, and contour. In this article, we present a case of a young female patient affected by right orbital-zygomatic-maxillary FD. She had developed facial asymmetry and malocclusion that were corrected using the Schuchardt-Kufner osteotomy technique. 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.

Obwegeser found serious complications such as partial or total The Schuchardt procedure can be used to shorten posterior maxillary height, but it is rarely used in the USA because it requires either an interdental osteotomy or a tooth extraction (Fig. 24.2). Fig. 24.2 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. This osteotomy through the cortex with the medial cut above the lingula and the lateral cut 1 cm below it Dental splinting (Schuchardt's, or brackets) Sufficient distance to tooth roots (approx.

14 Sep 2020 Schuchardt described the posterior maxillary osteotomy in the same year, as well as the diagonal, sagittal osteotomy of the mandibular ramus 

Indications 1. Post maxillary alveolar hyperplasia 2. Total maxillary hyperplasia (when combined with AMO) 3. 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 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). A second aim was to compare these data with data for adult pati … Schuchardt separated the pterygomaxillary junction allowing anterior repositioning. Bell’s research demonstrated the revascularization phenomenon, the ability to sacrifice the descending palatine arteries without compromising blood supply, and the ability for osseous healing from a complete maxillary osteotomy, thus providing the biologic Figure 8 Schuchardt's modification of the osteotomy (1954).11 Hugo Obwegeser was not satisfied with the known techniques of mandibular osteoto-mies.12 He retrospectively analyzed 50 cases operated in his hospital according to the technique by Kostečka.
