Weill Cornell Medical College offers state-of-the-art diagnosis and treatment of tumors affecting the skull base. The skull base is the area located at the floor of the cranial cavity. Because of the complexity of this area, skull base surgery is one of the most challenging procedures for a neurosurgeon to perform. The skull base surgery program at Weill Cornell Medical College crosses many disciplines, including those of the skull, head and neck, and brain. We have a multi-disciplinary team of specialists that works together to develop comprehensive treatment plans for patients with skull base tumors and other disorders. The College's team of specialists includes neuro-oncologists, radiation oncologists, neuro-otologists, neurosurgeons, neurologists, ophthalmologists, head and neck surgeons and psychologists. Neurosurgeons at Weill Cornell Medical College diagnose and treat skull base disorders using advanced 3-D imaging equipment, which provides extremely clear pictures of tumors. This allows for safer and more complete resections of tumors and resolutions of other disorders, and thus improved outcomes for patients. With the most advanced technology in radiosurgery and comprehensive services in radiation oncology, we provide the best care for a broad range of tumors in the ear and base of the skull. We have extensive experience in gamma knife radiosurgery, which is a safe, non-invasive, high precision device that treats many types of lesions, including deep-seated brain tumors and AVMs (arteriovenous malformations). In addition, our team of medical professionals has created and designed many treatment paradigms now being used routinely around the world. With access to intraoperative magnetic resonance imaging (MRI) and stealth image guidance, our surgeons perform minimally invasive procedures that ensure complete excision of tumors. Weill Cornell Medical College participates in ongoing clinical trials to advance treatment for skull base tumors. Our multidisciplinary team also continues to create innovations that will contribute to new treatment paradigms for complex skull base tumors.
