To reconstruct the affected areas of the face, patient-specific autogenic or alloplastic solutions are used. Tumor resection is often associated with the loss of essential, functional structures of the face ( 6). Without computer-assisted planning and navigation, therapy is only possible with difficulty ( 3– 5). The complex 3D structures of the face and head require a lot of experience and skill on the part of the surgeon. Especially during staging, computer-assisted planning and multi-planar as well as -modal evaluation and analysis of data (CT, MRT) have become indispensable and represent an essential pillar of tumor surgery and tumor management. Progress in the planning and implementation of computer assisted surgery (CAS) with the aid of 3D images for the area of the jaw and facial tumors has been recorded over the past two decades, particularly in order to optimize the interface-supporting procedure in tumor surgery ( 1, 2). The fact that the system makes the patient transparent for the surgeon and the procedure controllable facilitates a more precise and safer treatment oriented to a better outcome. The present work was able to demonstrate that the area of oncological surgery of the midface is a prime example of interface optimization based on the sensible use of computer assistance. These benefits of CAS in midface reconstruction found expression in positive changes in quality of life. These cases needed reduction of intra-orbital volume due to the tissue loss after resection which could be precisely achieved by CAS. Moreover, we evaluated the possibilities of primary midface reconstructions seizing CAS, especially in cases of infiltrated orbital floors. to a much more focused radiation therapy. This procedure enables the transparent, yet precise documentation of three-dimensional tumor borders which paves the way to a more feasible interdisciplinary exchange leading e.g. Furthermore, we demonstrate the use of navigated specimen taking called tumor mapping. Comparison of the two groups showed a higher rate of residual-free resections in cases of CAS application. Therefore, 60 patients diagnosed with a malignancy of the upper jaw has been treated, 31 with the use of CAS and 29 conventionally. The present study evaluated the beneficial use of CAS in the treatment of midfacial tumors with special regard to tumor resection and reconstruction. Computer assisted surgery (CAS) can provide the framework in this context. Therefore, the evaluation of the true three-dimensional tumor extent and the intraoperative availability of this information seem critical for a precise, yet substance-sparing tumor removal. In contrast, undertreatment followed by repeated re-resections can also not be an option. In some cases, this implied aggressive overtreatment with loss of the eye globe. Since decades, the surgeon’s goal of R0-resection has led to radical resections in the anatomical region of the midface because of the three-dimensionally complex anatomy where aesthetically and functionally crucial structures are in close relation.
