Better outcomes were achieved by Schuchardt who described a technique in 1955 in which the surface area of repositioned bone in contact was significantly increased. The first corrective osteotomy of the jaws was described in the middle of the 19th century by Hullihen (1849).

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. 5 mm) Osteotomy using round burrs (more gentle than a saw or Lindemann burr) Planning of incisions to preserve soft tissue and to avoid compromise of blood supply In the maxilla: absolute protection of palatal mucosa is essential Figure 2: Sagittal horizontal split osteotomy, as described by Schuchardt.5 Figure 3: Sagittal split osteotomy, as described by Obwegeser.6 Soon after the introduction of the technique important modiﬁcations were suggested. In 1961, Dal Pont7 advanced the lateral bone cut anteriorly towards the distal border of the second molar. Segmental osteotomy, according to Schuchardt-Kufner, comprises the elements 1.5, 1.6, and 1.7; impaction of the maxilla 3 mm in the front and 10 mm in the rear with a feed rate of 4 mm; pterygomaxillary dysjunction; and mobilization of the bone fragment ( Fig. 3). The results of Schuchardt's posterior maxillary osteotomy (1955) have been assessed differently in the literature. Follow-up examinations performed by Obwegeser (1964), Nwoku (1974) and Martis (1980) frequently showed a relapse.

Schuchardt started the studies on Sagittal Split Osteotomy in 1942, then Obwergeser and Trauner in 1957, Dal Pont in 1961, Hunsuck in 1968 and Epker in

For many years, and in some countries still, this technique has defined the term oral and maxillofacial surgery. 2007-03-13 · Sagittal split osteotomy (SSO) is a surgical technique largely employed for mandibular mobilizations in orthognatic procedures.

Segmental osteotomy, according to Schuchardt-Kufner, comprises the elements 1.5, 1.6, and 1.7; impaction of the maxilla 3 mm in the front and 10 mm in the rear with a feed rate of 4 mm; pterygomaxillary dysjunction; and mobilization of the bone fragment ( Fig. 3).

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. Better outcomes were achieved by Schuchardt who described a technique in 1955 in which the surface area of repositioned bone in contact was significantly increased.

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. 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.

Schuchardt operation is a good option for cases limited to the overeruption. In cases of overeruption with simultaneous op-posed alveolar deﬁciency, it is suggested to perform simulta-neous maxillary and mandibular surgical procedures: alveolar segmental operation, followed by a sandwich osteotomy on the opposing arch.
