As with nerve stimulation this sounds like a treatment that would be best suited to headaches with significant evidence of neuralgia. If other neuralgia treatments haven't done anything though--well, I'm sure that this surgery would only be considered if there's a good reason to believe that it would be helpful.
It's important to remember, I think, that NDPH is a pattern of symptoms, not a specific headache pathology. If Ashley is a good candidate for the surgery then I very much hope that it works. I'm just concerned if you're considering it because there doesn't appear to be any other choice. What lead Dr. Blake to suggest this specific treatment for your daughter's headaches.
My thoughts are with you.
