The average life expectancy after craniotomy is related to the primary disease as well as the physical state of the patient, and the patient may gain the same life expectancy as a normal person, or may die within a few hours.
1. Factors of primary disease: for example, benign brain tumor, which goes well during and after operation, usually does not significantly affect life expectancy; while malignant brain tumor, even though craniotomy is performed, it may still recur or metastasize after operation, which affects the prognosis. In addition, in some special cases of acute diseases, such as massive cerebral infarction, massive cerebral hemorrhage, etc., even if craniotomy is performed, the patient may die in a week or so. 2. Factors of the patient’s physical state: if the patient is old, with many foundations, poor cardiopulmonary function, serious coagulation disorders, etc., the risk of performing craniotomy is high, and there is a possibility that the patient will die during the operation.
Therefore, life expectancy after craniotomy, is affected by multiple factors and needs to be assessed according to the individual’s condition in accordance with medical advice.
