Craniotomy surgery is one of the most common types of brain surgery conducted to treat a brain tumor. It mainly aims at removing a lesion, tumor, or a blood clot in the brain by opening a flap above the brain to access the targeted area. This flap is removed on a temporary basis and again put in place when the surgery is done. Around 90 percent of the cases of brain tumors are diagnosed in adults aged between 55 and 65. Among children, a brain tumor is diagnosed within an age range of 3 to 12 years.
Craniotomy procedures are conducted with the help of magnetic resonance imaging (MRI) scans to reach the location precisely in the brain that requires treatment. A three-dimensional image of the same is achieved of the brain in conjunction with localizing frames and computers to view a tumor properly. A clear distinction is made between abnormal or tumor tissue and normal healthy tissue and to access the exact location of the abnormal tissue.
