Resection of an inferior pontine cavernous malformation using a far-lateral transcondylar approach.
BACKGROUND
When considering an approach to remove a symptomatic brainstem cavernous malformation, exposure and adequate visualization of the lesion with minimal morbidity should be the primary goals.


METHODS
We describe the use of the far-lateral transcondylar technique to access a cavernous malformation in the lower anterior pons.


RESULTS
This approach accesses the inferior belly of the pons in an inferior-to-superior direction, where the cavernous malformation approaches the surface between the root exit zones of the abducens (VI) cranial nerves.


CONCLUSIONS
We recommend adding this technique to the repertoire of approaches used to resect these technically challenging lesions in selected cases.
