Objective
There is controversy on whether lowering or restricting the level of sympathectomy can reduce compensatory sweating (CS). This study compared the results from sympathectomies performed to treat severe palmar hyperhidrosis using two distinct levels of T2–4 and T3–4.
Methods
One hundred and sixteen patients with primary palmar hyperhidrosis were randomly allocated to undergo either T2–4 sympathectomy treatment (T2–4 group) or T3–4 sympathectomy treatment (T3–4 group). Follow-up data were collected using a telephone questionnaire to assess efficacy, side effects, overall satisfaction, and factors affecting CS and the degree of satisfaction.
Results
There were no significant differences with respect to either CS or severe CS between the two treatment groups at 1, 6, or 12 months of follow-up. The total scores of the quality-of-life questionnaires after surgery were remarkably decreased compared with those before surgery in the two groups. However, no significant differences in quality-of-life scores were found between the two groups before surgery, or at 1, 6, or 12 months of follow-up. Age was predictive of severe CS at 6 months of follow-up (P = 0.045). Severe CS was inversely associated with patient satisfaction at 1, 6, and 12 months of follow-up.
Interpretation
The issue of whether lowering or restricting the level of sympathectomy reduces CS is controversial and needs more supportive evidence. Age may be a predictive factor for severe CS at 6 and 12 months of follow-up. Severe CS is the only known factor that affects patient satisfaction, and family history may also be associated with patient satisfaction.
