Figure 2.

Panel A shows an endoscopic view of a red and white tissue mass. Panel B displays surgical instruments manipulating tissue, with an arrow indicating a specific structure. Panel C presents another close endoscopic view of internal tissue. Panel D depicts a rounded, blood-covered tissue mass. Panel E reveals a narrow view of a surgical cavity. Panel F is a sagittal MRI scan of the head showing a boxed area near the pituitary region. Panel G shows a magnified MRI segment focused on the boxed region from panel F.

Simple reconstruction surgery technique diagram. (A) Make a cross-shaped incision through the dura mater at the base of the sella turcica, preserving the supporting structures at the four corners. (B) Following tumor resection, an arachnoid fistula (black arrow) was observed. Intraoperative CSF leakage was classified as Grade 3. (C) Cover the entire diaphragma sellae and the medial wall of the sellar region with artificial dura mater. Black star: Pituitary fossa. (D) Gelatin sponge packing of the pituitary fossa ensures full contact between artificial dura mater and the diaphragma sellae, directly covering the leak. (E) Porcine fibrin sealant sealing and fixation. (F,G) Postoperative pituitary MRI.
