Schuchardt altered the bone cut from horizontal sectioning in the mandibular ramus to an oblique sectioning. Download Citation | Craniomaxillofacial Fibrous Dysplasia: Conservative Treatment and Maxillary Osteotomy Using the Schuchardt-Kufner Technique | Fibrous dysplasia (FD) is a disturbance of the 2016-12-23 · 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). 2018-12-27 · 1927 - Wassmund - Le Fort I osteotomy with the pterygomaxillary junction left intact; elastic forces used to bring the maxilla forward 1928 - Axhuasen - Segmental osteotomy through the mid palate 1942 - Schuchard - Staged Le Fort I osteotomy, followed by pterygomaxillary separation; external traction used to bring the maxilla forward 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. 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).

OSTEOTOMY, ANTERIOR SEGMENT, MAXILLA The following CPT code(s) require prior authorization: Code Description 21188 Reconstruction midface, osteotomies (other than LeFort type) and bone grafts (includes obtaining autografts) 21206 Osteotomy, maxilla, segmental (e.g., Wassmund or Schuchard) The osteotomy design in a Le Fort I significantly impacts the ability to reposition the maxilla 3-dimensionally. The surgical technique presented allows for efficiency in completion of the osteotomies. In 1953, the sagittal ramus split osteotomy was introduced by Obwegeser. 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.

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.
