Gamma Knife® stereotactic radiosurgery

Gamma Knife® stereotactic radiosurgery is not actually a type of surgery at all – instead of opening the skull to remove a tumour or lesion, it is treated through the skin and skull using gamma radiation beams.This information sheet from Great Ormond Street Hospital (GOSH) explains about Gamma Knife® (also known as stereotactic radiosurgery), when it can be used and what to expect when your child comes to GOSH for assessment and treatment.
