The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.
Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

Secondary Effects of Sympathectomy - Disturbance of Sexual Function

If a portion of the autonomic nervous system is removed to modify a specific disease process, unrelated physiologic mechanisms will also be affected. The degree to which these other mechanisms may be affected often governs the selection of operative procedures. The results produced by interfering with mechanisms other than those for which the operation is performed might be designated as side-effects or secondary effects. . . .

We disagree that surgery and botulinum toxin are treatments of choice in severe cases of hyperhidrosis

The truth is exactly the opposite. Surgery is only rarely necessary, and the editorial quite properly warns of numerous surgical pitfalls, which include recurrence of hyperhidrosis, almost certain impotence, compensatory sweating, permanent neurological damage from anoxia, and death (their words). Botulinum toxin, which they recommend for axillary or plantar hyperhidrosis, requires 12 injections per axilla and 24-36 injections per foot. Even this horrendous procedure gives only 11 months' relief, and antibody formation may reduce long term efficiency.

Iontophoresis should be tried before other treatments

Iontophoresis is easy to perform, effective in about 90% of patients in two studies with 54 and 30 participants, free of hazardous side effects, and well accepted by almost all patients.

the Kuntz nerve played no part in the success or failure of ETS surgery

If you research the topic of ETS, you will come across various claims and counter-claims
about the importance or otherwise of the Kuntz nerve. The Kuntz nerve is a small nerve
fibre sometimes seen on the second rib not far from the main sympathetic chain. Its
function is not known in humans. Some web-sites on ETS claim success rates of up to
100% for facial blushing because they search for and destroy the Kuntz nerve(s). These
same people also claim to be able to correct failed ETS operations by reoperating and
destroying the Kuntz nerve.
At the meeting of the International Society for Sympathetic Surgery in Germany, May
2003, attended by a majority of the world’s experts in ETS surgery (including us), all but
one of the surgeons present were of the opinion that the Kuntz nerve played no part in the
success or failure of ETS surgery for facial blushing. We share this majority opinion.

diabetic autonomic neuropathy is due to a lesion of the sympathetic nerve supply to the skin

"We conclude that the diabetic anhidrotic syndrome, a form of diabetic autonomic neuropathy, is due to a lesion of the sympathetic nerve supply to the skin."
