Dear Jordan110.
I do allow my patients to fly after around 10 days from craniotomy in general. However, each case is different and you should discuss your situation with your neurosurgeon.
thanks
I had surgery to remove a pituitary tumor in a place away from home. I few home just a few days after surgery. At that point, I was still not permitted to lift. If you are concerned, do call your doctor's office and ask!
