OBJECTIVETo explore the predisposing factors for postoperative epilepsy in patients with gliomas.

METHODSA total of 258 glioma patients with complete clinical data receiving cranial surgeries were analyzed retrospectively. With gender, age, predominant symptoms, positive signs, history of preoperative epilepsy, time of epilepsy onset, tumor location, surgical approaches, cortical injury, arterial and venous injury, scope of tumor resection, postoperative edema, tumor pathology, tumor recurrence, number of operation, radiation therapy as the independent variables, the occurrence of postoperative epilepsy was analyzed as the dependent variable using logistic regression to identify the risk factors for postoperative epilepsy.

RESULTSHistory of preoperative epilepsy, surgical approaches, postoperative edema, tumor pathology and tumor recurrence were identified as the risk factors for postoperative epilepsy in glioma patients.

CONCLUSIONSPostoperative epilepsy severely affected the quality of life of glioma patients, and rigorous treatment targeting the risk factors may decrease the occurrence of postoperative epilepsy.
