At present, modern skull base surgery is a highly sophisticated interdisciplinary collaboration of various diagnostic and therapeutic disciplines. The overall goal is the treatment of complex tumorous, traumatic, vascular and inflammatory processes or developmental disorders of the skull base with preservation of function. The paper presents modern concepts, procedures and minimally invasive strategies in skull base surgery and also critically discusses the current trend to endoscopic and robot-assisted surgical techniques.

Total endoscopic or endoscopy-assisted surgical procedures are becoming more and more important for skull base surgery. In particular at the frontal skull base endoscopic procedures with planned opening of the subarachnoidal space have mostly replaced the microscope because of the good experiences in functional endoscopic sinus surgery (FESS). The advantages for the patients of endoscopic procedures with planned opening of the subarachnoidal space measured by criteria, such as mortality, morbidity or recurrence rate are unclear due to a lack of valid study data according to the criteria of evidence-based medicine.
