With the development of neuroscope technology,the indications for endoscopic surgery through the transnasal approach have expanded rapidly,including extra-sellar tumors and skull base tumors. Compared with traditional craniotomy,expanded endoscopic approach (EEA) has better tumor resection rate and postoperative neurological function. However,the risk of cerebrospinal fluid (CSF) leak after surgery is high,which can lead to dangerous intracranial infection and even endanger the patient's life. Postoperative skull base reconstruction is of great significance in reducing CSF leak. Currently,the use of vascularized nasal septal flaps has significantly reduced the incidence of postoperative CSF leak. This review summarizes the latest advances in skull base reconstruction methods,providing clinical references.
