"Bone removal only" decompression, pros and cons?

Posted , 4 users are following.

Hi, Folks - I'm brand new here. Got MRA results back on 8/1/16 saying "fullness in foramen magnum" got 2nd MRI to diagnose CM yesterday. I've got so many of the symptoms. Some have been with me since childhood, others began around 10 years ago, now, at age 50, I'm in bed much of the day and feeling surgery is likely to be my best shot at (hopefully) improved quality of life, and (fingers crossed) signficant recovery.

I read a great debate on another site about the pros and cons of "bone removal only" decompression. Apparently the recovery can be faster with this approach, and complications are said to be fewer. 

Those who think opening the dura is best cite less likelihood of regression, and need for repeat procedures as why the more invasive approach is better.

Do any of you have experiences to share, having had one or the other procedure?

    In my Chiari, I had a 4 cm tonsil on left side and 8 cm on the right side with it completely blocking the spinal canal.  I had the dura opened so they could go in an cauterize the tonsils so they would shrink back up into the skull. I think you have to open the dura if there is something like this that needs to be corrected. 

    So they put a dural patch on it after they cauterized it. 

    Post surgery, I didn't have any complications other than nausea (from the narcotics received in hospital) and dry heaves. I'm 57. So I blame all my other illnesses on the Chiari. 

    Hope this helps and Good Luck!!

    Hi Brinn,

    I just have my decompression  - invasive one, open the dura and cauterize my tonsil - my neuro surgeon Mr Flint, did not put dura as he said its less complications - hence that was 3 months ago, I am drug free (thanks GOD) not even paracetemol - I personally said: ''get the op as soon as you can.'' do not leave it too long

      Congratulations, b2wc97455 - this is great news! Like you, I want the best possible outcome, and as soon as can safely be done. Thanks for educating me about the approach your surgeon took with the dura. Sounds like a very smart way to go.
