SYMEON MISSIOS, M.D., FAANS
Bio
Dr. Missios is a board-certified neurosurgeon at Long Island Brain & Spine, specializing in both cranial and spinal procedures and with subspecialty training in the surgical and radiosurgical management of brain tumors and in minimally invasive endovascular neurosurgery.
Dr. Missios received his Bachelor’s of Science degree in Biological and Biochemical Sciences from Duquesne University, in Pittsburgh, PA where he graduated Magna Cum Laude. He obtained his medical degree from Dartmouth Medical School, in NH, where he was elected as a member of the Alpha Omega Alpha Honor Society. He graduated medical school with honors and was the recipient of the prestigious Dean’s Medal Award for the highest academic achievement in his class. He completed his internship and residency in neurological surgery at Dartmouth-Hitchcock University Hospital in NH and received his subspecialty training in the field of brain tumors at Cleveland Clinic, in OH, where he completed a fellowship in Neurosurgical Oncology and Stereotactic Radiosurgery. He continued his subspecialty training by completing a second fellowship in the field of Endovascular Neurosurgery and Neurovascular Critical Care at Thomas Jefferson University in Philadelphia.
Dr. Missios’ clinical expertise involves the treatment of benign and malignant tumors that originate in the brain or that have metastasized there. He has extensive experience in the use of advanced intraoperative neuronavigation techniques such as intraoperative tractography, brain mapping and electrocorticography that allow the safe resection of complex brain tumors that occupy critical areas in the brain. He is also an expert in stereotactic radiosurgery, a very precise way of delivering radiation to the tumor while sparing any radiation exposure to the rest of the brain, and is highly effective for the treatment of a variety of intracranial tumors.
Dr. Missios is also a part of the Stroke and Brain Aneurysm Center of Excellence at Good Samaritan Hospital Medical Center, the only Joint Commission Certified Comprehensive Stroke Center in the South Shore of Long Island. He received extensive training in endovascular neurosurgery at Thomas Jefferson University Hospital, one of the largest stroke centers in the country, and his expertise involves the surgical and minimally invasive endovascular treatment of stroke, brain aneurysms and other vascular neurosurgical pathologies.
In addition to his clinical expertise in the management of brain tumors, stroke and brain aneurysms, Dr. Missios’ clinical skills span a wide range including spine surgery for degenerative, traumatic or tumor pathologies as well as surgery for peripheral nerve disorders, brain and spine trauma and neuromodulation for intractable back and leg pain.
Dr. Missios has a very strong academic background and has been involved in more than 80 peer-reviewed publications. He serves as a reviewer for multiple neurosurgical journals. He is a member of the Population Health Research Institute of New York at CHS. His academic projects have won several awards including the Kenneth Shulman Award, awarded to the best research project presented at the annual meeting of the Joint Section of Pediatric Neurological Surgery, and 1st place award in the Socioeconomic Category at the 83rd annual meeting of the American Association of Neurological Surgeons.
