About the department

The neurosurgery department at Memorial Sisli Hospital Istanbul deals with diagnosing and treating patients with diseases of the brain, spinal cord and peripheral nerves. Neurosurgical intervention is preceded by diagnostics using the most modern equipment, including computed tomography, magnetic resonance imaging, angiography, and other diagnostic studies. Surgical interventions are performed in operating rooms equipped with the latest technology. Neurosurgeons successfully use advanced neuronavigation systems, neuromonitoring, CUSA ultrasonic surgical apparatus, O-arm intraoperative computed tomography, radiosurgical systems for stereotaxic interventions and many other innovations. This allows doctors to perform interventions with maximum safety and exclude damage to vital structures of the brain and spinal cord. The department employs specialists with excellent qualifications and vast clinical experience, which they have acquired in the best medical institutions in Turkey, Europe and the USA.

Tumours of the brain and spinal cord are one of the most frequent pathologies in the department's clinical practice. Treat malignant neoplasms of the nervous system can be performed for adults and children. The health of the nervous system of young patients is taken care of by a specially trained team of neurosurgeons who have extensive experience in treating congenital and acquired diseases in children. As a rule, the main stages of treatment are surgery, chemotherapy or radiation therapy. Treating injuries and conditions of the spine is also of particular interest to the department's specialists. The department's neurosurgeons successfully perform operations to treat spinal stenosis, myelocele, and congenital anomalies of the spine.
