Dr. McRackan adds, "Other side effects such as headache, weakness of the facial nerve, imbalance (due to treatment rather than from the acoustic neuroma) and visual problems are quite rare when Gamma Knife is performed for appropriate sized tumors." Permanent Hearing Loss a Reasonable Price to Pay Materials and methods: The median tumor margin dose was 15 Gy and the median tumor volume was 5.5 mL. More than 1,500 patients with AVM have undergone Gamma Knife radiosurgery at UPMC Presbyterian. To assess current evidence for gamma knife radiosurgery in the indications of arteriovenous malformations (AVMs), cerebral metastases (CMs) and acoustic neuroma (AN). Patients are not put to sleep for this procedure as it causes minimal pain and discomfort. There is no hair loss, as with some treatments.

Urinary urgency and frequency. careful patient selection and counseling are recommended given the higher risk of side effects. It would seem reasonable that the area of the brain irradiated and the dose of radiation given would be important factors that might influence this side effect, but this . We have used Gamma Knife radiosurgery to treat patients with brain tumors and metastases for 20 years. These complications included hemorrhage (eight cases), delayed cyst formation (eight cases), increase of seizure frequency (four cases), and middle cerebral artery stenosis and increased white matter signal intensity on T2-weighted magnetic resonance imaging (one case of each). Side effects may include tingling or numbness in the face (in up to 20-30% of patients), but this is usually mild if it does occur. The typical or "classic" form of the disorder (called "Type 1" or TN1 . The most immediately apparent effect are burns. MRI revealed a hyperintensity on T2-weighted images in the right temporal lobe 2.2 years after GKS treatment in Patient 1. During the mean post-GKRS follow-up period of 10.2 years (range, 5.4-30.6), 15 (8.3%) of our 181 patients experienced stereotactic radiosurgery-related, symptomatic complications. Patients usually leave the hospital the same day of the procedure. I did whole-brain radiation, then chemotherapy and later gamma knife surgery. The long- and short-term side effects of this procedure, if any, are minimal and transient. GKRS provides a highly conformal and selective therapeutic intervention in a single procedure performed with image guidance, achieving maximal precision.

It is effective. meningioma; gamma knife; GKS, gamma knife radiosurgery; MRI, magnetic resonance imaging; Although more than 90% of intracranial meningiomas are histopathologically benign, they frequently recur if removal is incomplete. Key CyberKnife treatment benefits Non-surgical and non-invasive No head frame is required Good cancer control Reduced incidence of common cognitive side effects Treatments may be completed in as little as 1-5 sessions within 1-2 weeks Most patients can continue normal activity throughout treatment Balance and dizziness issues are very common with acoustic neuroma, both pre- and post-treatment and can be long or short-term.

Long-term Side Effects: Cyberknife Radiosurgery: Despite receiving a dose similar to brachytherapy, long-term urinary effects are not common and rectal injury is rare; 20-30% patients develop erectile dysfunction One-millimeter accuracy protects surrounding tissues: External Beam Radiotherapy (EBRT) Intensity-Modulated Radiotherapy (IMRT) Unilateral hearing loss and tinnitus are common symptoms, and hearing loss can persist after treatment. This latest technology comes with certain advances that mean more patients may qualify as candidates for the treatment, and the ultra-high accuracy minimizes long-term side effects, improving outcomes. Some people may complain of a headache, which can be treated with over-the-counter analgesics.
