[The 2013 Sixto Obrador Award. A triple-axis topographical model for surgical planning of craniopharyngiomas. Part I: historical review of the topographical diagnosis and classification schemes of craniopharyngiomas].
This study reviews the historical evolution of pathological, neuroradiological and surgical evidence that influenced the topographical concepts and classification schemes of craniopharyngiomas. ⋯ A triple-axis topographical model for craniopharyngiomas that includes the degree of hypothalamus invasion is useful in planning surgical approach and degree of resection. The group of infundibulo-tuberal craniopharyngiomas associates the highest risk of hypothalamic injury (50%). The endoscopically-assisted extended transsphenoidal approach provides a proper view to assess the topography of the craniopharyngioma and its degree of adherence to the hypothalamus.
