The interpeduncular fossa approach for resection of ventromedial midbrain lesions

Written by

The complex anatomy of the brainstem, and the presence of important structures in close proximity to one another, mean that operating on lesions in this location provides a particular challenge to neurosurgeons. The anterior mesencephalic (or perioculomotor) entry zone has previously been described in surgery for lesions of the midbrain. The perioculomotor entry zone lies between the PCA and SCA, and in the medial fifth of the cerebral peduncle lateral to the oculomotor nerve. The authors of this article describe an approach through the interpeduncular fossa for tackling more medial lesions in this area.
