Amin B. Kassam, MDAmin B. Kassam, MD is Professor and Chair of the Department of
Neurological Surgery at the University of Pittsburgh School of Medicine, and
Director of the Minimally Invasive endoNeurosurgery Center at the University
of Pittsburgh Medical Center.
Dr. Kassam completed his medical and undergraduate education at the
University of Toronto and his residency training at the University of Ottawa.
He joined the faculty of the Department of Neurological Surgery at the
University of Pittsburgh in October of 1997 and spent the next year focusing
on microvascular surgery. Dr. Kassam has performed over 700 microvascular
decompression procedures for cranial nerve neuropathy and has provided a
unique perspective by using the endoscope to visualize and enhance difficult
regions. Since his appointment, he has also focused on building a
collaborative center to provide comprehensive care for complex pathology of
the skull base. This center builds on the strength of combining the talents of
surgeons from multiple specialties.
This allows for the use of proven conventional approaches in
conjunction with new minimally invasive endoscopic approaches to provide
safe and effective treatment for patients. This has culminated in the
development of the multidisciplinary Minimally Invasive endoNeurosurgical
Center (MINC). Dr. Kassam along with Carl Snyderman, MD, and Ricardo
Carrau, MD, from the Department of Otolaryngology, were directly involved
with the development of the Expanded Endonasal Approach (EEA). This
approach represents an entirely new paradigm to remove complex lesions of
the skull base and brain without incisions.
The center, under the direction of Dr. Kassam, has pioneered and
developed much of the technology and instrumentation used during the EEA
surgeries. With continued research and experience, he now uses the EEA for
most tumors affecting the skull base. Dr. Kassam has performed over 3,000
neurosurgical procedures including over 1,000 minimally invasive endoscopic
procedures. Dr. Kassam remains active in cerebrovascular surgery and has
helped to develop a program to better understand the genetic alterations that
lead to the development of intracranial aneurysms.
In July 2006, Dr. Kassam was named interim chairman of the
Department of Neurological Surgery and on May 1, 2007, Dr. Kassam was
appointed as the department's third permanent chairman. Since then he has
focused on increasing interdisciplinary activities between neurosurgery and
radiology, medical, radiation and surgical oncology, anesthesiology,
neurology, and otolaryngology. It is hoped that these cooperative ventures
will lead to new innovations in care for patients with a variety of neurologic
abnormalities. Dr. Kassam has over 100 publications in the peer reviewed
literature, an additional 21 book chapters currently published or in press, and
is funded by both industry and the NIH. He lectures extensively nationally and
internationally on surgery of the cranial nerves, skull base and on minimally
invasive endoscopic techniques.
William A. Friedman, M.D.William A. Friedman, M.D. A.L. Rhoton Professor and Chairman of the
Department of Neurosurgery, was born in Dayton, Ohio on April 25, 1953. He attended
high school in Cincinnati, Ohio. He graduated in 1970 as a National Merit Scholar and
attended Oberlin College. There he was elected to Phi Beta Kappa before moving on
to the Ohio State University College of Medicine. Before graduating summa cum laude
from medical school in 1976, he was elected to the Alpha Omega Alpha honor society
and received the Maurice B. Rusoff Award for excellence in medicine. In 1976, Dr.
Friedman moved to the University of Florida in Gainesville, Florida. He performed a
surgical internship and a neurosurgical residency, from which he graduated in 1982.
During residency training he did basic neurophysiology research as an NIH
postdoctoral fellow (1 F32 NS0682-02). In 1982, he joined the faculty of the
Department of Neurosurgery, as an Assistant Professor. He received an NIH Teacher
Investigator Award (NS 00682-02), from July, 1982 - July, 1987, which funded further
research into the basic neurophysiology of spinal cord injuries. In addition, this award
supported the development of one of the first intraoperative neurophysiology
monitoring laboratories, subsequently used to monitor thousands of neurosurgical and
orthopedic surgical cases. Dr. Friedman served as Medical Director of the
Intraoperative Neurophysiology Service from 1982-1992.
Dr. Friedman was promoted to Associate Professor and received tenure in
August, 1987. In August, 1991 he was promoted to Professor. He currently serves as
Chairman of the Department of Neurosurgery and the A. L. Rhoton Professor of
Neurosurgery. He is the author of more than 200 articles and book chapters and has
written a book on radiosurgery. He is a member of numerous professional
organizations. Most notably, he has served as President of the Congress of
Neurological Surgeons, the Florida Neurosurgical Society and the International
Stereotactic Radiosurgery Society. He is the Past Editor of Neurosurgery On Call, the
Internet homepage of organized neurosurgery.
In 1986, Dr. Friedman began collaborative work with Dr. Frank Bova, which
led to the development of the University of Florida radiosurgery system. This system
was subsequently patented by the University of Florida. The commercial version of the
system has become one of the most popular radiosurgical systems worldwide. Drs.
Friedman and Bova received the 1990 UF College of Medicine Clinical Research Prize
in recognition of this accomplishment. Dr. Friedman is the leader of a multidisciplinary
radiosurgery team which has treated over 2000 patients, published more than 100
papers and chapters, produced many international meetings, and educated hundreds
of visiting physicians. This team is engaged in many ongoing research projects in the
new radiosurgery/radiobiology laboratory in the UF McKnight Brain Institute. Most
recently, they Drs. Bova and Friedman received an NIH R01 grant to support their
