Extended pterional transtemporal transtentorial approach
Extended pterional transtemporal transtentorial approach (EPTT).
Through anatomic comparative analysis the EPTT approach provides better exposure and is more appropriate than the subtemporal transtentorial approach (ST approach) for large and giant petroclival tumors predominantly in the posterior cranial fossa with extensive invasion to parasellar structures and the cavernous sinus 1).
