Roberto Alexandre Dezena (June 8th, 1976, in São João da Boa Vista) is a world-renowned neurosurgeon. He currently holds the position of Associate Professor and Chief of the Neurosurgery Department at the Hospital de Clínicas da UFTM, Federal University of Triângulo Mineiro. Additionally, he is the Supervisor and Founder of the Neurosurgery Residency Program at this institution. Dezena also serves as the President of the Brazilian Academy of Neurosurgery for the period from 2022 to 2024.

Education
Dezena completed his medical degree at the former Triângulo Mineiro Medical School, now known as UFTM (Federal University of Triângulo Mineiro), in 2003, and specialized in neurosurgery at the Santa Casa de Misericórdia de Ribeirão Preto in 2009.

He obtained his Ph.D. in Surgical Clinic from the Ribeirão Preto Medical School at the University of São Paulo in 2011, with a thesis entitled "Pre, Intra, and Post-Ischemic Hypothermic Neuroprotection in Temporary Focal Cerebral Ischemia in Rats."

In his thesis, Dezena undertook an in-depth investigation into the mechanisms of neuroprotection against cerebral ischemia, a clinically challenging condition with significant impact on neurosurgical practice. His study focused on the application of hypothermia at different stages of the ischemic process, aiming to determine its efficacy in reducing neuronal damage. Through an experimental approach using rats as models, Dezena conducted a detailed computational morphometric analysis to assess the effects of pre, intra, and post-ischemic hypothermia. His findings indicate that both pre and intra-ischemic hypothermia demonstrated neuroprotective effects, while post-ischemic hypothermia showed no significant benefits. These results contribute to the understanding of neuroprotection mechanisms in cerebral ischemia and provide valuable insights for the development of more effective therapeutic strategies.

Later, he completed a postdoctoral fellowship at the Federal University of Triângulo Mineiro, which he finished in 2014. After specializing in neurosurgery, Dezena participated in fellowship programs in neurosurgery at Eberhard Karls University of Tübingen (Germany), Hiroshima University (Hiroshima, Japan), Saint Louis University (United States), and Technische Universität Dresden (Germany).

Dezena is a neurosurgeon specialized in various areas of neurosurgery. His expertise encompasses vascular and oncological microneurosurgery, involving surgical interventions on delicate vascular structures of the nervous system and the removal of brain tumors. He also excels in skull base surgery, focusing on addressing lesions located in this complex region. Additionally, Dezena is an expert in endoscopic neurosurgery, utilizing minimally invasive techniques to treat conditions within the skull or spinal column. His experience also includes pediatric neurosurgery, which focuses on the diagnosis and treatment of neurological conditions in children, as well as spinal surgery, where he performs procedures for deformity correction, lesion treatment, and tumor removal. As a neurotraumatologist, he treats traumatic injuries to the central nervous system, and more recently, he has ventured into aerospace medicine, where his work focuses on the health of pilots and astronauts, considering the impacts of extreme environments on the nervous system and cognitive performance.
