A brain tumor is a mass/growth of abnormal cells inside the brain. A brain tumor surgery is performed for the removal of tumors from the head without causing any major damage. It is the most common treatment for a brain tumor. A brain tumor surgery helps to remove the tumor completely or tries to heal it by partial removal. Many benign (non-cancerous) tumors can be treated only by surgery. Most malignant (cancerous) tumors, however, require treatment in addition to surgery, such as radiation therapy and/or chemotherapy.
To remove the whole tumor
To partially remove the tumor to slow its growth and help with the symptoms
To drain the build-up of excess fluids inside the brain
To help identify and diagnose other treatments required, like chemotherapy
To prevent internal bleeding inside the brainThe procedure carried out for a brain tumor depends on the type, size, and location of the tumor inside the brain.
During a brain tumor surgery, the doctor cuts out a small part of the scalp bone from the skull. The part of the skull removed is called the bone flap. The bone flap is temporarily removed to expose the brain tissue and create an opening that allows the doctor to operate on the brain and remove the tumor entirely, or partially.
A brain tumor surgery is usually carried out in the following way –
On arrival at the hospital, the patient is made to lie down and be given anesthesia before the procedure.
When the patient is asleep, the head is attached to a skull fixation device attached to the table, to help keep the head still during the surgery.
A tube is placed inside the lungs to help with breathing during the surgery.
A line is made on the head to mark the path of incision for the doctor to see.
After this, an antiseptic is used to prepare the area of the incision. Sometimes, a part of the head is shaved off as skin incisions are usually made behind the hairline. Clips may be applied to minimize the bleeding during the surgery and the muscles and are flapped back and secured.
The doctor then starts with the brain tumor surgery with the help of the required medical equipment.Preparations for brain tumor surgery will be instructed by your doctor based on the health condition and the intensity of the surgery.
