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