I do not have personal experience. My surgeries on my c-spine were not done endoscopically but the web-sites I went to talked of following benefits:
The benefits of endoscopic surgery are threefold. Since the size of the incisions are smaller, the recovery from surgery is much quicker. There is also less pain and less damage to the surrounding tissues.
If you are wanting to know more or ask if someone that had this done would let you know if it was successful for them I suggest re-posting your question with a little more info. Good Luck and God bless.
