Purpose:
To compare the efficacy, adverse reactions, quality of life, and patient satisfaction of percutaneous radiofrequency (RF) thoracic sympatholysis at different rib-based anatomic targets for primary palmar hyperhidrosis (PPHH).
Materials And Methods:
Patients with PPHH were divided according to the target, namely, the upper edge (Group U) and lateral border (Group L) of the fourth rib; there were 30 patients (mean age, 24.9 years; women, 31, 51.7%) and 60 cases in each group. The Hyperhidrosis Disease Severity Scale (HDSS) and Dermatology Life Quality Index (DLQI) were assessed.
Results:
From before RF sympatholysis to 12 months after, the proportion of patients with HDSS Grades III and IV (100%-26.7%) and the DLQI (19.78 ± 5.08 to 4.98 ± 4.18) decreased significantly (P < .001). At 3, 6, and 12 months after RF, the HDSS grades were better in Group L than in Group U (P = .005, .002, and .004). At 6 and 12 months after RF, the DLQI in Group L was lower than that in Group U (P = .012 and .016), and at 1, 6, and 12 months after RF, patient satisfaction was higher than that in Group U (P = .025, .014, and .009). Adverse events were mild; 8 patients (13.3%) demonstrated compensatory hyperhidrosis at 12 months after RF, and there was no difference between the 2 groups (P = .448); neuralgia and pneumothorax also did not differ (P = .522 and .643).
Conclusions:
RF sympatholysis targeting the lateral border of the fourth rib had higher efficacy, better quality of life, and higher patient satisfaction.
