Amir R. Dehdashti, MD, FACS, FMH is the Director of Cerebrovascular Neurosurgery Research at North Shore University Hospital and Associate Professor of Neurosurgery at Hofstra Northwell School of Medicine in New York. Dr. Dehdashti completed his neurosurgery training under Professor de Tribolet in Geneva, Switzerland, and is board certified in neurosurgery by both the Swiss Board and the Board of the European Association of Neurosurgical Societies. Dr. Dehdashti completed fellowship training in both cerebrovascular and skull base surgery, including endoscopic skull base surgery, at theToronto Western Hospital. He is one of the few dually trained cerebrovascular and skull base surgeons in the country with two dedicated and separate fellowships. Dr. Dehdashti has significant clinical expertise in performing complex intracranial surgery including cerebral bypass procedure which is performed only by a handful of expert neurosurgeons in the country. Dr. Dehdashti has published over 100 papers and has given more than 200 lectures at different national and international meetings on topics relevant to cerebrovascular, skull base tumors, pituitary tumors and cranial nerve disorders including trigeminal neuralgia. He has been involved in several retrospective and prospective studies relating to cerebrovascular neurosurgery. Dr. Dehdashti's clinical expertises include cerebrovascular surgery (aneurysm, AVM, brainstem cavernous malformation, Moyamoya disease, cerebral revascularization), carotid endarterectomy, minimally invasive surgery for aneurysms (mini craniotomy), minimally invasive endoscopic skull base surgery (pituitary and skull base tumors), surgery for cranial nerve disorders (trigeminal neuralgia, hemifacial spasm, glossopharyngeal neuralgia), skull base surgery, craniovertebral junction pathologies and acoustic neuroma surgery. His basic science and laboratory research is focused on molecular biology of brain AVMs. He is actively involved in the executive committees of North American Skull Base Society and Cerebrovascular Section of the AANS.
