Houston Stereotactic Concepts
About the Scientific Director
Dr. Philip L. Gildenberg received a B.A. degree in Physiology from the University
of Pennsylvania in 1955, his M.D. and an M.S. in Neurophysiology from Temple
University Medical School in Philadelphia, Pennsylvania in 1959 followed by a
Ph.D. in Neurophysiology from Temple University in 1970.
He is:
•        Director of the Houston Stereotactic Concepts;
•        Clinical Professor of Surgery (Neurosurgery) at Baylor College of Medicine,
       Clinical Professor of Radiation Oncology at Baylor College of Medicine; and
•        Medical Director of Restoration Robotics, a company devoted to robotic hair transplantation surgery.
Dr. Gildenberg retired from the clinical practice of neurosurgery in October, 2001.

He is the Past-President of the American Society for Stereotactic Functional Neurosurgery and is the Past-President of
the World Society for Stereotactic and Functional Neurosurgery. Dr. Gildenberg has had the privilege of participating
as a visiting professor at more than 30 medical institutions worldwide.
A world-recognized authority in minimally invasive neurosurgery, Dr. Gildenberg has
designed several techniques to facilitate biopsy and resection of brain tumors.  He holds several patents concerning (1)
a means of using CT scanning to measure cerebral blood flow, (2) several devices for correlating coordinate systems
between various types of stereotactic apparatus, (3) a system to guide the neurosurgeon in resection of brain tumors by
presenting a virtual reality view, integrating a video image of the operating field with a computer generated picture of
the brain tumor derive from a CT or MRI scan, (4) the use of an audible to guide the surgeon in brain tumor surgery,
and (5) a system to use stereotactic techniques in robotic cosmetic surgery, and has several additional patents pending
concerning semi-robotic suturing.

In addition, he has written extensively in the field of functional neurosurgery, that is, surgery for movement disorders
(such as Parkinson's disease and spasmodic torticollis), pain (particularly cancer pain), and epilepsy surgery. In 1997,
Dr. Gildenberg was honored to receive the Spiegel-Wycis Medal from the World Society of Stereotactic and
Functional Neurosurgery, and in 2003 a Distinguished Service Award from the American Society for Stereotactic and
Functional Neurosurgery.

He is a member of the:
•        American Society for Stereotactic and Functional Neurosurgery
•        World Society for Stereotactic and Functional Neurosurgery
•        American College of Surgeons
•        American Association of Neurological Surgeons
•        Congress of Neurological Surgeons
as well as numerous other professional organizations and societies.

Dr. Gildenberg and Professor Ronald Tasker of Toronto have published the
of Stereotactic and Functional Neurosurgery,
which is considered to be one of the
milestone publications in the field, bringing together authors from the various disciplines
involved in stereotactic surgery to present the most comprehensive book yet published in
that field.

Dr. Gildenberg and Dr. Richard A. DeVaul wrote the book
The Chronic Pain Patient -- Diagnosis and
, which involves patients with particularly difficult long-term pain problems.

He edited an annual series on stereotactic radiosurgery (the use of localized radiation to
treat brain tumors or vascular malformation of the brain). He was the Editor of the journal
Stereotactic and
Functional Neurosurgery
from 1975 to 2002.

Dr. Gildenberg worked for 13 years, beginning as a medical student, with Dr. Ernest A. Spiegel and Dr. Henry T.
Wycis, the doctors who invented the field of human stereotactic surgery just over 50 years ago, and has been active in
the field for almost 45 years. His original contributions to neurosurgery, particularly stereotactic and functional
