Our team approach to patient care brings together highly specialized neurosurgeons and otolaryngologists dedicated to safely removing skull base tumors, pituitary tumors, as well as other types of brain tumors, and lesions through endonasal endoscopic surgery.
This minimally invasive approach enables surgeons to:
- Remove tumors and lesions directly through the nose and sinuses, without incisions on the face or skull
- Access areas of the brain that are difficult to reach with traditional surgery
- Perform surgeries on tumors once considered inoperable
Endonasal endoscopic surgery uses an endoscope, a small telescope-like device equipped with a high-resolution video camera to view and access tumors and lesions through the nose. With the guidance of state-of-the-art medical imaging, the tumor can be dissected and removed with the specially designed instrument.
