What is a Chiari Decompression Surgery??
This is a subject that I'm not to fond of, but it doesn't scare me. After you read this you may think I'm either lying or just plain nuts not to be scared of this surgery. I have good reasons not to be scared. No one in recent history has died from the decompression, there are some that have died due to other illnesses and complications from them. I know nothing is 100%, but this is very close. That is why I'm comfortable with the surgery.
Decompression is not a 'cure' for Chiari. It could make all of my symptoms go away, make some go, or cause more symptoms. I have thought about the risks of the decompression and they don't compare with my desire to have my life back.
The surgery sounds more complicated than it really is. I'll be placed under general anesthesia and positioned face down. A small area in the back of the head is shaved and prepared for surgery (I'm ready for that right now!). An incision will be cut down the back of my head and neck. A small area of the bone at the base of the skull is removed to enlarge the posterior fossa. The area is opened to expose the membrane covering the brain called the dura. An incision will probably be made in the dura to see the cerebellum and upper spinal cord. The cerebellar tonsils are shrunk using a tiny instrument, called the electrocautery. A patch is then needed to cover the area that is now enlarged to 'house' the cerebellum. There are several different types of patches: your own dura stretched, donor dura from a cadaver and others. None of these will be my patch. Until my neurosurgeon told me what type of patch I will have I didn't know about this one, I'll be patched with the lining of a cows heart (no jokes please!). This is a little strange for me, but I will gladly accept that patch. The incision is then closed with sutures below the skin and sutures or staples, I'll have sutures, on the skin.
The procedure generally takes 2-3 hours. The patient is usually awakened in the operating room and transferred to the recovery room for close observation. The hospital stay is generally from 3 to 5 days. The sutures or staples will come out in 7 to 10 days after surgery.
Recovery from Decompression Surgery.
All of this is up to the patient, the doctors, and the severity of the Chiari. The severity has little to do with the millimeters of herniation. Some Chiarians I have read about have had a speedy recovery of a few months some take a year or so.
I recovered quickly. I did not counting on getting up right after surgery and walking away with little need for help.
Pain in the neck was the worst problem. My neck was very stiff, but that was mostly gone by the one month mark. I have moments where I get a bad headache, but people have headaches everyday. I have not had a headache that was as bad as before the surgery.
