Abstrakt:	Introduction: Anatomical individuality is key to reduce surgical trauma and obtain a better outcome. Nowadays, the advances in neuroimaging has allowed us to analyze this anatomical individuality and to plan the surgery. With this objective, we present our experience with the OsiriX software. Technical Description: We present three different applications as example of forty procedures performed. Case 1: Patient with a premotor cortex convexity parasagittal meningioma; Case 2: Patient with a nonfunctioning pituitary macroadenoma operated on 2 years ago in another institution, achieving a partial resection by a transsphenoidal approach; Case 3: Patient with bilateral middle cerebellar peduncles lesions. OsiriX Software was used for surgical planning. Volumetric CT and MRI images were fused and 3D reconstruction images obtained, to analyze anatomical relationships, measure distances, coordinates and trajectories, among other features. Discussion: OsiriX software is a useful, open-source and free software tool that provides the surgeon with valuable information. It allows to study individual patient's anatomy and plan a surgical approach in a fast, simple, inexpensive and safety way. In Case 1 the software let us analyze the relationship of the tumor with the surrounding structures in order to minimize the approach's morbidity. In Case 2, to understand the unique anatomic characteristics of an already operated patient giving us important information regarding pathways and need for extra bone removal, achieving a complete tumor resection by an endoscopic transnasal approach. In Case 3, allowed us to obtain the stereotactic coordinates and trajectory for a not visualizable CT scan lesion. Conclusion: When expensive neuronavigation systems are not available, OsiriX is an alternative for neurosurgical planning, with the aim of reducing trauma and surgical morbidity.
