Brain Surgery Without a Knife
The simple things in life have become quite challenging for Howard Katz. "I basically have only about 20 percent vision in this left eye," Katz says. Katz strains to read, his walking is unsteady, and he even had to give up his favorite pastime -- softball. "I can't hit the ball, and it's quite dangerous to try to catch the ball," he says. A benign brain tumor about the size of an egg is pressing against Katz's optic nerve. Today, surgeons will remove it without ever cutting into his skull. ![]()
First, doctors map the tumor's exact location in the brain. Then, they use a navigation system to guide them to the site. Video cameras allow them to see precisely where the probe is moving inside the skull. Surgeons use thin instruments to go through the nasal passage to the brain. "Once the patient's head is connected to the scan coordinates, then anywhere the probe travels inside the head shows up on the screen with a very high accuracy," Dr. Mayberg says.
Now that the tumor is out, Katz is ready to go home, and doctors say his vision should gradually improve every day.
