Detailed Description of Business Dr. Louis is currently the Director of the Skull Base and Pituitary Tumor Program at Hoag Memorial Hospital in Orange County, Southern California. His expertise also includes endoscopic and minimally invasive treatment of benign and malignant brain tumors, sellar and parasellar tumors and skull base tumors. Through the use of cutting-edge neuroimaging and neuro-navigational equipment, he utilizes the concept of keyhole neurosurgery, minimizing the damage to surrounding brain, vascular and soft tissue structures. Dr. Louis believes that most brain and skull base tumors can be resected through small openings or by utilizing naturally occurring orifices. This approach has been demonstrated to decrease post-operative pain, minimize neurologic complications and shorten the length of hospitalization, resulting in better outcomes for his patients.
