Percutaneous Radiofrequency Sympatholysis in the Treatment of Primary Palmar Hyperhidrosis: A Retrospective Case-Controlled Study of Rib-Based Anatomical Targeting

PurposeTo 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 MethodsPatients 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.ResultsFrom 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).ConclusionsRF sympatholysis targeting the lateral border of the fourth rib had higher efficacy, better quality of life, and higher patient satisfaction.
