Abstract [en]

Surgeons are used to treat bone defects with autograft material due tothe good chance that it will be successfully incorporated by defect sitetissues. However, problems of donor site morbidity, sufficient donormaterial, bone tissue quality and crafting the correct shape fromavailable donor material increase dramatically with the size of thedefect. Large skull defects ([100 cm2) are not uncommon sequelae of trauma, cancer, stroke, and re-constructive surgery. An aesthetically correct and precisely tailored reconstruction of the defect by means of prefabricated implants remains challenging because the majority of current implant design techniques are heavily dependent on subjective procedures. Dealing with prefabricated implants allows the reduction of surgery intervention time, and therefore reduces the risks for the patient and the costs of surgery. We transfer existing anthropological methods to neurosurgical planning in order to reduce the dependence on subjective skills and to improve the custom implant form. The purpose of this study is to compare two different approaches allowing the generation of implant surfaces.
