“…12,36 Prior to the availability of high-resolution imaging, osteotomies were usually made along fracture lines, 37,38 the goal of which was to recreate the original fractures and mobilize the zygoma. 36,39 Not uncommonly, osteotomies were performed in conjunction with malar augmentation procedures to further address aesthetic concerns. 36 Selective partial osteotomies have also been described, and typically incorporate interposition grafts in an effort to splay the partially mobilized segment.…”

Secondary deformities of the zygoma are a rare entity, thanks to the adoption and refinement of open reduction and internal fixation techniques. These injuries are often difficult to treat due to the unique structural, functional, and aesthetic properties of the zygoma. Purely cosmetic defects can often be managed with implants; however, functional deficits generally require mobilization, correction, and subsequent fixation of the defect(s). Performing the necessary osteotomies to mobilize the zygoma is the most crucial part of the procedure, and had traditionally been executed without the use of computer aids. Planning for and performing this step was very difficult and frequently resulted in unsatisfactory outcomes. Recent advancements in virtual mapping and planning have obviated the need for guesswork and have resulted in improved functional and aesthetic outcomes following repositioning. This article will discuss the use of implants, osteotomies, and computer-assisted design/modeling (CAD/CAM) in addressing secondary deformities of the zygoma.

“…In modern protocols this can, however, be avoided if a pyramidal osteotomy is performed in the lateral walls of the maxillary complex, making the maxilla slide inferio-anteriorly. In 1949, Moore and Ward [15] recommended horizontal transection of the pterygoid plates for maxillary advancement. However, this technique was abandoned due to the incidence of severe bleeding in most cases.…”

Orthognathic surgery is mostly performed to correct developmental or acquired oral and maxillofacial skeletal deformities OMSDs . During the past three decades, significant advances in surgical osteotomy techniques and instrumentation have been developed and carried out in orthognathic surgery. However, the basic surgical principles have more or less remained unchanged. "t the same time, numerous surgical techniques have been developed and refined and used by surgeons in the field of oral and maxillofacial surgery. These techniques have treatment of the most complex dentofacial deformities with confidence. "dditionally, it has been possible to predict the results of the treatment. "lthough the initial surgical techniques for correction of anterior mandibular open bite were reported as early as the late s, widespread use of currently acceptable techniques began in the middle of the last century. Detailed surgical planning is essential for a successful outcome. The treatment involves an accurate treatment plan, correct type of instruments for a specific procedure, a thorough surgical routine, and adherence to the guidelines for each routine. "lthough similar orthognathic surgical techniques are used, there are multiple important differences related to each osteotomy. It is essential for the surgeon to understand these differences in order to provide an effective and safe surgical care for the patient with facial anomalies. Choosing an optimal method of osteotomy depends on many factors, including the indication for treatment, the goal of therapy, patient profile, underlying medical conditions, and the magnitude of surgical movement. The major objective of this chapter is to provide practical guidelines and principles of osteotomies and commonly used techniques. These guidelines are based on a review of the current literature and the author's personal experience. The chapter focuses on the history of orthognathic surgery, anatomical considerations, indications for different osteotomies, and the surgical technique for each osteotomy. Techniques such as the Le Fort I, II, III osteotomies, segmental osteotomies of the maxilla, bilateral sagittal split osteotomy "SSO , bilateral vertical osteotomy "VO genioplasty, segmental osteotomy of the mandible, and the chin wing osteotomy are described.
