About the Program:

Cranial and Skull PageDr. Samy Youssef MD, PhD, Director of the University of Colorado Skull Base Surgery program, is board certified and fellowship trained with a national/international reputation  in the treatment of complex brain tumor and vascular surgery. 

The University of Colorado Hospital Skull Base Program provides advanced, comprehensive care in the Rocky Mountain region for patients with complex skull base tumors, cerebral aneurysms, meningiomas, acoustic neuromas, pituitary tumors, trigeminal neuralgia, and head and neck cancer. The care for such challenging lesions is founded on close multidisciplinary care. 

Our skull base team consists of collaborative, multidisciplinary providers including neurosurgeons, otolaryngologists, head and neck surgeons, oculoplastic surgeons, oncologists, radiation oncologists, neuropsychologists, and neuropathologists.   Our team-based approach has lead the University of Colorado to treat more patients with brain tumors than any other hospital in the region.  

Our skull base team provides patients with the safest and most effective surgery by combining our expertise with the latest technological advancements in endoscopic cranial procedures, fluorescein-guided tumor resection, image-guided tumor resection, intraoperative MRI, and minimally invasive tumor surgery.  

Dr. Youssef was recently featured for treating cerebrospinal fluid cysts of thalamic origin using state-of-the-art endoscopic cranial procedures.
