transcochlear

A new approach to tumors of the skull base is described. This approach is accomplished by forward extension of the translabyrinthine opening into the cerebellopontine angle. […] We provide the case histories of four patients in whom this approach was successfully used in removal of skull base tumors.

The objective of transtemporal surgery is wide skull-base exposure obtained by precise anatomic management of the temporal bone. […] The transpetrosal surgical routes can be classified broadly into anterior and posterior. The posterior transpetrosal approaches include the retrolabyrinthine, translabyrinthine and transcochlear, whereas the anterior approaches are extensions of the basic middle fossa approach.
