What causes difficulty breathing after pituitary tumor surgery?

Postoperative dyspnea following pituitary tumor surgery is usually caused by medications, nasal packing, or similar factors. The main reason for breathing difficulties after pituitary tumor surgery is the use of hemostatic materials such as gelatin sponge to pack the nasal cavity during the procedure, which can lead to nasal obstruction and difficulty breathing. This is a common postoperative reaction that typically resolves on its own after a period of observation. After pituitary tumor surgery, patients should avoid getting the surgical wound wet to prevent infection.
