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.

a watery nasal fluid is formed dur-

A role for the nasal cycle in respiratory defence
R. Eccles

Simultaneous optimal stimulation of the autonomic nerves resulted in vasoconstriction, especially of the capacitance vessels. Hence, nasal congestion may be related more to a withdrawal of sympathetic discharge than to an overactivity of the parasympathetic nerves.
