During surgery, the patient is usually put under general anaesthesia for around 24 hours. The patient is usually kept on a heating blanket positioned over an alternating pressure air mattress as the procedure is an extensive one.
The patient’s blood pressure is intentionally kept abnormally low, especially when the main blood vessel, the petrous carotid, is dissected. Usually, past experience with bleeding during surgery will ensure that doctors start fresh frozen plasma and platelet infusions after the patient has gone through at least 4 full units of blood. This practice is usually standard procedure, and has been shown to prevent potentially deadly intracranial bleeding during and after the surgery.
Minimally-invasive or Endoscopic skull base requires a small cut in the nose through which removal of growths by a neurosurgeon is made possible. The neurosurgeon uses an endoscope, which is a very small, very thin tube with a light attached at the front. The operating team usually takes the help of an MRI to make sure that all of the growth has been removed.
Open Surgery requires a large incision, generally behind the hairline. To reach and eliminate the growth, the surgeon needs to remove parts of bone from the bottom of the skull.
Along with endoscopic and open surgery, chemotherapy and radiation therapy si also required for patients with cancerous growths in their craniums.
