Table A3.
New recommended approaches in retrospective analysis of the preoperative situations of all eleven patients with a paravermal trans-cerebellar approach in this study. Later HOD refers to the occurrence of HOD on cMRI within 12 month-follow up. Abbreviations: DN = dentate nucleus.
| Age, Sex | Diagnosis WHO° | Later HOD | Tumor Localization | Associated Cyst | Original Operative Approach | New Recommended Approach |
