There were no operative mortalities, minor complications occurred in 22%. Initial success rate was 88%. Median follow up was 93 (24-168) months, response rate to the questionnaire was 85%. Sixty-nine per cent of patients continued to have relief of initial symptoms, whereas patient satisfaction rate was 56%. CS was present in 42 patients (68%). Long-term satisfaction rates per initial indication group were 42% for facial blushing and 65% for hyperhidrosis (n.s.), and CS was present in 79% vs 61%, respectively.
CONCLUSION:
ETS appears a safe treatment for upper limb hyperhydrosis with acceptable long-term results. For excessive blushing, however, long-term satifaction rates of ETS are severely hampered by a high incidence of disturbing compensatory sweating. ETS should only be indicated in patients with unbearable symptoms refractory to non-surgical treatment. The patient information must include the long-term substantial risk for sever CS and regret of the procedure.
