Data Collection and Analysis in Brainstem Surgeries

The hypothesis is that the structural documentation and analysis of the data of demographics, neuroimaging, IONM and clinical outcomes can help to further standardize the use of such equipment for detecting the integrity of the corticospinal tracts. We want to confirm that the retrospectively data analysis of neuroimaging, IONM and clinical outcomes does help to understand these methods better in the surgical management of brainstem lesions, and therefore, improve the safety of brainstem surgery.
