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.

significant number of primary hyperhidrosis patients (more than 70%) were so pleased with the results that they decided to forgo the surgery


At the beginning of our study, thoracic sympathectomy was indicated indiscriminately to all primary hyperhidrosis patients. The authors observed a number of patients who were dissatisfied with the results obtained from this technique, particularly due to the undesirable but frequent side effect of compensatory hyperhidrosis. Hyperhidrosis is a condition that deeply affects the individual's emotional component, and many of them, despite being warned previously, are not psychologically prepared to address this new situation. The authors then included a psychologist in the study and directed the patients for routine psychological evaluations to prepare and better select them for surgery. In addition, the authors began to study a pharmacological formula to medicate these patients for the same purpose. Oxybutynin is an anticholinergic drug that has been used safely at high doses (up to 15 mg/day) to treat micturition disorders, and a side effect observed in these patients has been diminished sudoresis. Studies conducted by our group have documented the clinical benefits of a low dose of oxybutynin (10 mg/day). The authors found that a significant number of primary hyperhidrosis patients (more than 70%) were so pleased with the results that they decided to forgo the surgery [50-53].
