Abstract
The infratemporal fossa type A (IFT-A) and the modified transcochlear approach are
used to remove glomus jugular tumors type C and petroclival tumors extending to the
prepontine cistern, respectively. Anterior rerouting is a key step in IFT-A, whereas
the modified transcochlear approach involves posterior rerouting. The aim of this
study was to analyze facial nerve function after application of the two procedures.
One year after surgery, anterior rerouting was associated with excellent to good outcomes
(grade I to III) in 94% of the cases, while posterior rerouting was associated with
good outcomes (grade III) in 70% of the cases.
