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.

No compensatory sweating after botulinum toxin treatment of palmar hyperhidrosis

No compensatory sweating after botulinum toxin... [Br J Dermatol. 2005] - PubMed - NCBI: "Recordings were made at 16 skin areas and compared with subjective estimates of sweating.
Following treatment, palmar evaporation decreased markedly and then returned slowly towards pretreatment values, but was still significantly reduced 6 months after treatment. No significant increase of sweating was found after treatment in any nontreated skin area.
Successful treatment of palmar hyperhidrosis with botulinum toxin does not evoke compensatory hyperhidrosis in nontreated skin territories."

not exposing patients to the risk of experiencing the side effects of sympathectomy

The use of oxybutynin for treating ... [An Bras Dermatol. 2011 May-Jun] - PubMed - NCBI: "Treatment of facial hyperhidrosis with oxybutynin is a good alternative to sympathectomy, since it presents good results and improves quality of life, in addition to not exposing patients to the risk of experiencing the side effects of sympathectomy."
