Using Polyglycolic Acid Mesh Prevents Cerebrospinal Fluid Leakage

This study plans to enroll patients with pituitary tumors who need to undergo surgical treatment according to current routine medical standards. After the tumor tissue is removed, the integrity of the spider web or skull base will be thoroughly checked by endoscopy during the operation to confirm whether there is any cerebrospinal fluid leakage. At the end of the operation, use a 100\*50\*0.15mm, green sheet-like Navi tissue repair patch, cut it aseptically to fit the size of the defect for repair (the common case is 2\*3.5cm defect), and place it on the spider web or skull base Tissue repair at the surgical site to prevent cerebrospinal fluid leakage.
