N2 - Surgery for craniopharyngiomas, especially in childhood and adolescence, has evolved from an era of aggressive strategies - with the primary goal of gross total removal and accepting an impaired functional outcome - to a more individually tailored therapy that avoids immediate treatment-related and long-term morbidity. Modern imaging techniques and a wider understanding of hypothalamic risk factors have led to surgical strategies adapted to the localization of these inhomogenously grown pathologies. Whereas purely infradiaphragmatic as well as supradiaphragmatic/infrachiasmatic tumors have a favorably surgical outcome with higher gross total resection rates in experienced hands, lesions within the third ventricle extending beyond the mammillary bodies remain a problem. The same is valid for lesions beyond 3 cm in diameter, more or less independent of their localization. Aside from the traditional microscopic approach via the subfrontal or pterional craniotomy, transsphenoidal approaches and other minimal invasive surgical methods, e.g., catheter implantation into cystic formations of the tumor have become popular. Radiotherapy, with its risks and limitations, can effectively be added to avoid recurrences. Nowadays, surgery as part of an interdisciplinary treatment strategy is still the typical first choice. However, taking the patient's long-term prognosis into considertaion, the surgical complication rates have to be minimized.
