Organization profile
Penn State College of Medicine's Department of Neurosurgery is dedicated to providing the highest quality neurosurgical care possible. The department offers a range of state-of-the-art care to referring physicians and their patients, including Gamma Knife radiosurgery, deep brain stimulation, neurotrauma and critical care, neurosurgical oncology, pediatric neurosurgery and more.
The department aims to provide the highest quality, most state-of-the-art, most patient-centered care possible for a number of conditions, including brain, spine and peripheral nerve tumors; concussion; epilepsy; movement disorders; stroke and brain hemorrhage; and traumatic brain, spine and nerve injuries.
As part of its commitment to innovation in the practice of neurosurgery, the department places a strong emphasis on research in developing the next new treatment for tumors of the nervous system, repairing nerve damage and surgical approaches through clinical and basic science research. This includes clinical trials, clinically-based research, preclinical and translational research.
Meanwhile, the department strives to educate the neurosurgeons of the future through electives for MD students and a comprehensive seven-year, ACGME-accredited neurosurgery residency.
