A Denver-based neurosurgery practice has become the first in its region to use radiosurgery technology developer Zap Surgical Systems' Zap-X gyroscopic radiosurgery platform on a patient, according to Zap.
William Lawson of Edwards, CO, was treated at Neurosurgery One of Littleton, CO, for acoustic neuroma, a benign tumor on the nerve between the inner ear and the brain that can cause hearing loss, dizziness, and balance challenges, the company said.
Stereotactic radiosurgery for brain tumor treatment is a noninvasive alternative to whole-brain radiotherapy, Zap-X noted.
