"I think the surgeons may not be aware of the long term consequences of denervation"

Email response from Dr. Ahmet Hoke of  John Hopkins School of Medicine,  School of Neurology - Specifically I asked him his opinion on three things:

1. What was his opinion of ETS in terms of risks vs benefits
2. His opinion on why Thoracic surgeons would advertise a surgical reversal approach when, as he sees it, it would  have a very low probability of success
3. His opinion on the Davinci Robot Reversal article regarding surgical reattachment of the sympathetic nerves

1. It all depends on the risk benefit analysis, for some patients yes it may make sense as not everyone develops as severe side effects.
2. I think the surgeons may not be aware of the long term consequences of denervation.

The paper you refer to is not a good model of what happens to the patients because they cut the nerve and immediately repaired it. In such immediate repairs, the ganglia does not loose it's neurons and can regenerate. A better model would be to cut the nerves, wait 6 months and then do the repair; I suspect the recovery would be a lot less.
