Steven L. Giannotta, MD
Chair and Professor of Neurological Surgery
Keck School of Medicine of USC
Steven L. Giannotta, MD, chair of Neurological Surgery, joined the Department of Neurosurgery at USC in 1980. He earned his medical degree and did his residency at University of Michigan. He is involved in many local, national and international committees and organizations. Dr. Giannotta has gained recognition for his work in cerebrovascular disease of the brain and spinal cord. He has surgically treated over 1000 intracranial aneurysms. In conjunction with his associates, Dr. Giannotta has developed a comprehensive approach to the gamut of cerebrovascular conditions. Techniques utilized in this comprehensive program include but are not limited to microsurgical clip ligation for aneurysms, coil embolization for aneurysms, microvascular excision, embolization, stereotactic radiosurgery using the Gamma Knife for arteriovenous malformations, carotid endarterectomy and extracranial to intracranial bypass procedures for cerebrovascular occlusive disease. Dr. Giannotta also has an interest and special expertise in surgical approaches to the cranial base. He has surgically removed more than 400 acoustic neuromas and along with several colleagues in otolaryngology has developed a team approach to complex cranial base lesions including acoustic neuromas, meningiomas of the cranial base, complex aneurysms that require cranial base approaches and other benign conditions affecting the base of the brain and skull. Complex conditions may require several modes of therapy including surgical excision, embolization, and stereotactic radiosurgery using the Gamma Knife.
