Our goal is to improve people's lives through innovation in research, education and patient care.

The Dardinger Microneurosurgery Skull Base Lab is a neurosurgical, educational and research facility that is part of the Department of Neurological Surgery in The Ohio State University College of Medicine. The lab was established in 2006 by Mario Ammirati, MD, MBA, a professor of Neurological Surgery who also directs the lab and serves as director of skull base neurosurgery at Ohio State.

Our vision is to train neurosurgeons in mastering approaches to the skull base by integrating sound anatomical knowledge of the skull base with cutting-edge intraoperative technology. This vision is implemented by providing a research environment where, by dissecting anatomical specimens and using equipment similar to that found in the operating room, the neurosurgeon becomes conversant with established skull-base approaches and is stimulated to think of new ways of operating on skull-base lesions.

The “What if?” question is at the core of laboratory philosophy. What if I would use a different approach or different technology to reach an area of the skull base? Would that solve some of the clinical problems encountered in the operating room? Would it help decrease morbidity? These questions are studied and answered in the laboratory. If laboratory results are satisfactory, they are taken back to the operating room to be evaluated in a clinical setting, completing the translational research cycle.

The laboratory thrives on cross-collaboration among neurosurgeons, radiologists, ear nose and throat (ENT) surgeons, and basic biotechnologist scientists, and also on interactions among undergraduates, medical students and neurosurgeons in a diverse cultural environment.

The laboratory encourages cooperation with industry by sharing knowledge, thus creating an interactive platform where ideas may be generated, discussed and implemented.

Mario Ammirati, MD, MBA

Director, Dardinger Microneurosurgical Skull Base Laboratory

Dr. Ammirati's clinical interests include skull-base surgery, benign and malignant brain tumors, and degenerative spine disease. His research focuses on microneurosurgical anatomy of the skull base and brain-drug delivery systems. He earned his MD at the University of Naples in 1977 and completed residencies in neurological surgery at the University of Naples (1980) and Northwestern University (1987).
