Gamma Knife Radiosurgery Cost in Singapore

A. Upon discharge from the hospital after Gamma Knife Radiosurgery in Singapore, the patients are advised to stay in the country for about two to three weeks for recovery. This duration of stay is recommended to complete all the necessary follow-ups and control tests to ensure that the surgery was successful.

A. Apart from the Gamma Knife Radiosurgery cost, there are a few other daily charges that the patient may have to pay. These are the charges for daily meals and accommodation outside the hospital. These charges start from USD 150 per person.

A. After the Gamma Knife Radiosurgery takes place, the average duration of stay at the hospital is about a day. The doctor's team reviews the patient's recovery during this time with the help of blood tests and imaging scans. Once they feel that everything is on track, the patient is discharged.

A. Gamma Knife Radiosurgery hospitals in Singapore are very highly rated. This rating is calculated based on different parameters such as the attitude of the nurses, cleanliness, quality of food, and the pricing policy.

A. Gamma Knife surgery is a noninvasive radiation therapy procedure that treats cancers and disorders of the brain and upper spine using computer-guided planning. Highly concentrated energy beams are delivered to a designated treatment region by the Gamma Knife. The damage to the surrounding tissue is reduced by this kind of radiation.

This operation isn't a surgery, despite its name, and it doesn't use any blades. The name "gamma knife" refers to the accuracy of gamma rays. These are photons, which are electromagnetic radiation particles with high energy. Gamma rays may precisely target a specific region of your brain without making incisions in your body, just like a surgical knife.

A. The radiation used in Gamma Knife surgery is intended to stabilize, reduce, or eliminate a tumor or lesion. Small abnormalities of the brain, can be treated with Gamma Knife surgery like:

• Malignant and noncancerous brain tumors
• Abnormalities in blood vessels.
• Nerve abnormalities

The following tumor types are frequently treated by Gamma Knife surgery:

• Acoustic neuromas (vestibular schwannomas).
• Brain metastases.

Some of the most common conditions that Gamma Knife surgery treats include:

• Arteriovenous malformations (AVM)
• Epilepsy.
• Symptoms of Parkinson's disease or essential tremor.
• Trigeminal neuralgia.
• Pituitary adenomas.
• Acoustic neuroma.

A. Gamma Knife does not suit all types of brain tumors. It is useful for small to medium-sized, well-circumscribed tumors, especially for benign tumors like meningiomas, pituitary adenomas, and schwannomas. It also can be applied to the metastatic tumor with less than 3-4 lesions and in difficult-access areas. However, it is less effective for large tumors greater than 3-4 cm, invasive tumors like glioblastomas, or tumors that are rapidly growing or spreading. Also, multiple large tumors in different brain regions may not be suitable for Gamma Knife. Tumors located near critical structures, such as the brainstem, pose a higher risk when treated with Gamma Knife. Hence, its usage is carefully determined based on tumor size, type, and location, often requiring a consultation with a medical team to assess its suitability.

A. Although there are usually few risks associated with the operation, of Gamma Knife surgery.

• A headache.
• feeling tired.
• Nausea and vomiting.
• Skin discoloration and bruises at the pin implantation locations.
• tingling or numbness on the scalp where the pins were inserted.
• loss of hair (only if a tumor is near the scalp).

Among the severe (but rare) side effects are:

• Brain swelling.
• Seizures.
• Bleeding (hemorrhage in the brain).
• Difficulties breathing.

A. Treatment with Gamma Knife usually lasts 1-2 hours. There are no surgical interventions; the patient leaves the hospital after the procedure. The treatment includes a few stages:

• Preparation (30-60 minutes): The patient is positioned using a head frame placed over the head. The frame is secured to the cranium with local anesthesia to minimize discomfort while attached.
• Imaging (15-30 minutes): MRI or CT scans are made to map the tumor location and size precisely.
• Treatment (30-60 minutes): The patient is placed under the Gamma Knife machine, where the radiation is delivered through multiple focused beams. This is typically 30-60 minutes, depending upon the size and complexity of the tumor.

Overall, the actual treatment is very short, the whole procedure from preparation to imaging usually spans 1.5 to 2 hours. Usually, the patient can go home the same day.

A. The success rate varies with the type, size, and location of a tumor or condition for radiosurgery using Gamma Knife. For benign brain tumors, including meningiomas and acoustic neuromas, the success rate in controlling the tumor is typically reported between 80% and 95%. For malignant tumor cases, such as metastatic brain cancer, the local success rate for tumor control may range from 50% to 80%. Some studies showed a better response for trigeminal neuralgia, with a successful result of 80-90% in the improvement and reduction of pain following treatment for only one session. An AVM success varies between 60% and 90%, depending upon the size and location. Gamma Knife is very effective for smaller tumors and those conditions in sensitive areas of the brain, though its efficacy may still decline for larger or more complicated cases. Long-term effectiveness will depend on the tumor's response to radiation.
