How I do it: the frontal basal interhemispheric approach for craniopharyngioma resection

The frontal basal interhemispheric approach (FBIA) provides wide access to the chiasmatic cistern, retrochiasmatic space, and lamina terminalis for craniopharyngioma removal. We introduce in detail the anatomical structure related to the FBIA, the surgical techniques of craniotomy, and how to prevent the surgical complications. The FBIA provides a satisfactory surgical corridor for craniopharyngioma resection.
