Skull fractures take a few months to heal. When fracturing the skull the healing process takes a lot longer than any other fracture, like a fracture in the wrist or foot. Because of how much was damage and depending on the area of the fracture and the extent of the damage, the healing process could take up to a year, and in some cases even longer. Once you fracture your skull the healing process also includes the healing of the brain itself. You can't just fracture the skull and get on with your life. Depending on the force that fractured your skull you can end up with memory loss, brain damage, and other nerve problems.

I am assuming that craniomoty is intended to mean craniectomy. If this is the case, then the answer is no. By breaking this word into its subdivisional parts, or combining forms (crani/o and -tomy), it means surgical removal of a portion of the cranium (or skull). This procedure is used to eleviate intracranial pressure, to accomodate for swelling of the brain, or both after the occurance of a traumatic event. A depressed skull fracture could be the said event, which causes ICP and therefore indicate the need of a craniectomy.
Arachnoid cysts can cause chronic remodeling and thinning of the adjacent skull. So--while I've personally never seen a case of skull fx directly overlying an arachnoid cyst (general diagnostic radiologist, 6 yrs in practice)--it certainly would seem that the involved portion of skull would be relatively more susceptible to fracture in the event of trauma.
