Has anyone found a good video that shows and describes decompression surgery?

If so, please post a link... I've found some but there is no sounds or words, so it's hard to tell what they are doing. Some others I have found are not just craniectomy and laminectomy. I just want to SEE and HEAR at the same time what is actually going to happen.

Beeba, thank you for your response, but I have watched several of them, just not exactly what I was looking for. I am scared, as most are, but I am very curious also. In general I like to watch surgeries and stuff like that, it really interest me. I really don't think it would scare me anymore than I already am. Thank you though!
