Just like other specialties, modern Neurosurgery often requires the use of a microscope to properly treat conditions such as slipped disk in the waist and neck, surgery for vascular lesions of the brain (aneurysms, vascular malformations, tumors), and spinal cord surgery. The use of a surgical microscope is now necessary in every neurosurgical unit and is combined with other infrastructures such as the endoscope, the neuronavigation and others. The use of the microscope in combination with percutaneous surgery, endoscopy and neuromonitoring, improves the effectiveness and safety of surgery. At the same time, blood loss, the risk of neurological damage, hospitalization time and recovery time after surgery are drastically reduced.
