Upper dorsal thoracoscopic sympathectomy for palmar hyperhidrosis: improved intermediate-term results.
OBJECTIVE
The purpose of this study was to examine the immediate and mid-term results of thoracoscopic upper dorsal (T2-T3) sympathectomy for primary palmar hyperhidrosis.


METHODS
From June 1993 to October 1994 we performed 106 sympathectomies on 53 patients with palmar hyperhidrosis. Thirty-four female patients and 19 male patients ranging in age from 15 to 44 years, (mean 23.1 years) were studied. Both sides were operated during the same surgical procedure. The T2-T3 ganglia were resected by electrocuting with a hook and were removed for histologic examination. Follow-up for a mean of 19.25 months was obtained on 52 patients (104 operated limbs).


RESULTS
All limbs were completely dry at the end of the procedure, and hyperhidrosis did not recur during the whole follow-up period. Short-term postoperative complications (mainly atelectasis, pneumonia, pneumothorax, and hemothorax) occurred in six (11.3%) patients. Long-term sequelae were observed in 43 (81.1%) patients and included Horner's syndrome (9 patients, 17.3%, one side only in each patient), neuralgia (7 patients, 13.5%), and compensatory hyperhidrosis (35 patients, 67.3%). These sequelae were not permanent in all cases, and the degree of severity was variable. Six (11.5%) patients, three of whom regretted being operated, were dissatisfied with their results: one because of Horner's syndrome, one because of persisting neuralgia, and four because of compensatory sweating.


CONCLUSIONS
Despite the large number of postoperative long-term sequelae, 88.5% of patients expressed subjective satisfaction from the procedure. Obtaining 100% of dry hands on mid-term follow-up makes this approach rewarding.
