Cell body reorganization in the spinal cord after elective surgery to treat palmar sweating

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.

After sympathectomy in rats there is an increase in osteoclast-mediated bone resorption as well as an increase in the number of osteoclasts on the sympathectomized side

Paper: Osteoclastic Activation In Periapical Lesions After NPY Knockout (IADR/AADR/CADR 87th General Session and Exhibition (April 1-4, 2009)): "After sympathectomy in rats there is an increase in osteoclast-mediated bone resorption as well as an increase in the number of osteoclasts on the sympathectomized side compared to the control. These findings suggest an inhibitory effect of the SNS on bone resorption via osteoclasts. Our objective was to determine if an SNS mediator, neuropeptide Y (NPY), affects osteoclastic activity after pulpal exposure."
