Brainstem surgery

When the lesion involves or points toward the floor of the fourth ventricle, a standard suboccipital approach through the vermis suffices. Lesions presenting in the cerebellopontine angle or the lateral pons may be safely approached through a standard retromastoid craniectomy. A more direct (perpendicular) access can be obtained by a standard subtemporal-transtentorial approach when the lesion is high and lateral, by a combined subtemporal-suboccipital approach when the lesion extends more inferiorly, and by a combined subtemporal-presigmoid approach for the more anteriorly located lesions. Anterior or anterolateral lesions of the highest aspect of the pons or of the mesencephalon can be readily accessed by the pterional-anterior temporal approach or by a standard subtemporal approach. Dorsal mesencephalic lesions require a supracerebellar/infratentorial approach or, when they extend more inferiorly, an occipital transtentorial approach. When the ventral aspect of the lower brain stem is involved, the lateral suboccipital approach works well 1)
