Abstract: With the increase of experience in expanding nasal endoscopic approaches and the updating of instruments and equipment,the application of endoscopy is developing towards larger and more complex skull base surgeries.These also lead to larger skull base defects,posing challenges for skull base repair.The larger skull base defects significantly increase the probability of postoperative cerebrospinal fluid leakage.These also promote higher requirements for skull base reconstruction technology.The review summarizes various methods and detailed treatments for skull base reconstruction,in order to clarify the repair techniques and optimal choices for skull base defects in nasal endoscopic surgery.

Key words: endoscopic surgery, nasoseptal flap, skull base reconstruction, cerebrospinal fluid leak
