This atlas offers a comprehensive overview of osteotomies performed on the calvaria and midface for both syndromic and non-syndromic craniosynostosis. It presents a systematic approach, beginning with calvarial osteotomies. The author introduces a general type of osteotomy that can be applied for total vault remodeling in cases of total synostosis. These osteotomies can also be modified and used in single or combined synostoses. To shape the calvaria, the book describes the use of metal plates as a scaphold. These plates can be prebent on 3-D models and used to fix the segments after osteotomies. Following that, resorbable osteosynthesis is performed, and the metal plates are subsequently removed. This unique approach, combined with standardized osteotomies, ensures highly predictable results that are not currently described in textbooks. The book includes clinical examples for each type of synostosis and various combinations, including two-stage procedures and combinations with distraction techniques. These examples provide surgeons with a solid foundation for addressing different cases. In the chapter on midface osteotomies, the book explains the access and technique for performing the LeFort-III osteotomy using cadaver and clinical figures. It covers all types of LeFort-I to III osteotomies and their combinations through clinical cases. The book illustrates the osteotomies, osteosynthesis, distraction techniques, and combinations using clinical examples. Additionally, the book demonstrates the method of computer planning, the fabrication of osteotomy guides, and the use of preformed plates to define the position of the segments. The book's primary objective is to serve as a surgical guide that transcends the boundaries of medical specialties. Given that this type of surgery is often performed by different specialists across institutions and countries, the book aims to facilitate cooperation and provide a practical application tool for surgeons beyond offering a clinical overview.

Abstract: Purpose Reconstruction of orbital wall fractures is demanding and has improved dramatically with the implementation of new technologies. True-to-original accuracy of reconstruction has been deemed essential for good clinical outcome, and reasons for unfavorable clinical outcome have been researched extensively. However, no detailed analysis on the influence of plate position and surface contour on clinical outcome has yet been published. Materials and methods Data from a previous study were used for an ad-hoc analysis to identify predictors for unfavorable outcome, defined as diplopia or differences in globe height and/or globe projection of >2 mm. Presumed predictors were implant surface contour, aberrant implant dimension or position, accuracy of reconstructed orbital volume, and anatomical fracture topography according to the current AO classification. Results Neither in univariable nor in multivariable regression models were unfavorable clinical outcomes associated with any of the presumed radiological predictors, and no association of the type of implant, i.e., standard preformed, CAD-based individualized and non−CAD-based individualized with its surface contour could be shown. Conclusion These data suggest that the influence of accurate mechanical reconstruction on clinical outcomes may be less predictable than previously believed, while the role of soft-tissue−related factors may have been underestimated
