There are many reasons for the development of epilepsy, and one of the major ones is intracranial occupancy, skull fractures, brain contusions and their craniotomy. Some patients with brain tumors may develop epilepsy before surgery, while others may develop it after craniotomy, either immediately after surgery or months or years later, in relation to damage to the surrounding brain tissue structures by the tumor itself or scarring of the brain tissue caused by the surgery. Thus, in theory, any patient with a brain tumor is at risk for epilepsy regardless of whether or not they have ever undergone surgery, but there is no medical way to predetermine which small percentage of these patients will develop epilepsy. Once epilepsy occurs after brain tumor surgery, the following measures should be considered: 1. Firstly, cranial MRI or CT examination should be performed to understand the condition of the operated area, and if there is bleeding, hydrocephalus, tumor recurrence and other conditions, corresponding treatment measures should be taken; 2. The company’s main goal is to provide a comprehensive range of products and services to the public. Most postoperative epilepsy can be controlled.
