Endoscopic brain surgery is a minimally invasive procedure which involves using narrow endoscopes and surgical tools (often developed by the surgeons themselves) inserted through the nasal passage to remove tumors as large as baseballs. In endoscopic brain surgery, an endoscope is put through the nasal passages and an incision is made in the back by an otolaryngologist (an ear, nose and throat doctor) and then handed off to a neurosurgeon to remove tumors at the base of the brain. This endoscopic technique to operate on the brain is also called "minimally invasive endonasal surgery". It was pioneered and refined in adults over the last decade by surgeons at UPMC and the University of Pittsburgh School of Medicine and is now a viable option for tumors in children and in many instances for tumors that were once deemed to be inoperable.
