The occipital transtentorial approach resulted in a significantly lower extent of resection when compared to the supracerebellar infratentorial approach (p = 0.04), even after multivariate analysis (p = 0.006). There was no significant difference between the location of residual tumour relative to the superior colliculi between the two approaches (p = 1.00). There was a significant incidence of radiological occipital lobe ischaemia from the occipital transtentorial approach (p = 0.04). Within our series, we did not demonstrate a consistent location of residual tumour relative to the surgical approach chosen. Whilst there was a significant difference with regards to the extent of resection between approaches, in the context of small comparative groups this is difficult to draw far-reaching conclusions from.
