Treatment Options For Glioblastoma

Craniotomy

To access the tumor, surgeons have to first perform a craniotomy. During this surgery, the surgeon removes a portion of the skull bone so they can see the patient's brain. The removed section is referred to as the bone flap. After the surgery, the flap is put back into place and secured. In some cases, the surgeon might use CT scanning or an MRI to guide them through the procedure. This is especially important when they need to get to a particular part of the brain to provide treatment.

To use imaging with this procedure, the surgeon uses either markers placed superficially on the scalp or a frame. The combination of surgery with imaging might be used to get a biopsy to assess the tumor or to differentiate between healthy tissue and the tumor. Surgeons will also do this surgery as part of a tumor debulking or removal surgery. There are different craniotomy types, and the best one ultimately depends on tumor location.
