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.

Eliminates the input of central signals to the pineal gland

N-acetyltransferase Activity

These data indicate that superior cervical
sympathectomy abolishes the N-acetyl-transferase
rhythm by elimination of the input of central signals
to the gland. These signals appear to regulate the
N-acetyltransferase rhythm in the normal rat by
regulation of the release of norepinephrine from the
sympathetic terminals within the pineal gland.
