Transthoracic endoscopic sympathectomy for primary palmar hyperhidrosis in children.

Primary palmar hyperhidrosis often starts in childhood. It usually causes academic and social disabling at the age children begin primary school. This study included 65 children (44 girls and 21 boys, mean age 13.5 years) who underwent one-stage bilateral transthoracic endoscopic sympathectomy. The proper sympathetic segment was visualized in almost all cases and electrocautery ablation was performed. The immediate postoperative course was uneventful in all cases and no major morbidity was encountered. Horner's syndrome did not occur in any case. All patients were discharged the day of surgery or after an overnight stay. The duration of follow-up was from 6 months to 3 years. Although compensatory sweating was found in 40% of the patients, long-term satisfaction was reported in 63 cases (96%). This procedure is effective, simple, and is recommended as the method of choice for surgical treatment of severe upper extremity hyperhidrosis in children.
